What Rob McElhenney Taught Me About Shop Management [E222]
2026/02/04
Thanks to our Partners, Pico Technology and Autel
Watch Full Video Episode
A random YouTube Shorts interview turns into a surprisingly sharp lesson in leadership. Matt shares a story from Rob McElhenney about working with Danny DeVito—and how DeVito’s humility and audience-awareness reveal something shop owners and managers can use immediately: collaboration beats ego, and if you want to reach a demographic (customers or employees), you’d better listen to them. Process matters. Culture matters. And the best people in any field tend to be the most open to input.
Matt talks about:
Rob McElhenney (It’s Always Sunny in Philadelphia, Wrexham co-owner, Ryan Reynolds connection)Working with Danny DeVito (also Taxi, Twins)The key moment: DeVito asks Rob what to say during an improv gap because:DeVito knows what’s funny to his generationBut Rob knows what’s funny to the target audienceSo DeVito wants direction to serve the project, not his ego
The Big Takeaways
Process matters more than outcomeThe “how” shapes culture, quality, retention, and long-term success.Great collaboration can be surprising—but it shouldn’t beEven top-tier people can be genuinely curious about your perspective.If you’re targeting a demographic, listen to that demographicMarketing, messaging, shop vibe, even hiring… all improve when you seek input from the group you want to attract.Openness is a leadership signalApproachable leadership reduces fear of dismissal/condescension and increases idea-sharing.Ego-check is good business“What’s best for the shop?” beats “what do I prefer?”Retention + recruiting bonusWhen employees feel heard and respected, they stay—and they tell others.
Memorable Lines
“You hired me to be the old guy… but you’re not going for my generation.”“Be a leader, not a dictator.”“Lesson number one: pay attention to YouTube Shorts… don’t just mindlessly scroll.”

Mr. Baseball [E221]

Watch Full Video Episode
Matt uses the movie Mr. Baseball (Tom Selleck as Jack, an aging Yankees player traded to Japan) as an analogy for life in the automotive repair world—especially for veteran mechanical/technical specialists whose bodies start breaking down and whose production (and pay) can drop as a result. The core theme: your role can evolve from “hour-cranker” to leader/mentor, but that requires radical honesty, ego-checking, and intentional changes—from physical maintenance to skill expansion to management systems that properly reward wisdom.
Key points & takeaways
The “Mr. Baseball” analogy
Jack believes he’ll dominate, but reality shows a hole in his swing and a body that’s not keeping up.His old talent used to hide the problem—until it doesn’t.The turnaround begins when he accepts reality, retrains, and recommits.
Auto repair parallel: age vs. mileage
It’s not always “age”—it’s the mileage, injuries, wear, and accumulated strain.As bodies degrade (knees, backs, shoulders, hips, neck), production drops, and pay plans tied heavily to output can punish experience.
Ego check: redefining value
When you can’t “crank hours” like you used to, value doesn’t disappear—it changes.Veterans often become natural leaders even if they don’t recognize or accept it.Leadership, mentoring, and stabilizing the team have real economic value—if the organization is willing to see it.
Management responsibility
Shops can’t afford to “cast blind eyes” to what veterans contribute beyond billed hours.The goal is optimizing the whole organization (the unit), not just individual output.If compensation and structure ignore mentoring/leadership value, the industry risks driving out the people who make everyone else better.
Action steps for the veteran specialist
Take care of the body: whatever works—massage, chiro, yoga, tai chi, mobility work, sleep/mattress upgrades, recovery habits.Expand skill sets into areas that are less physically taxing but high value (systems, diagnostics, workflow support, training others).Be honest and matter-of-fact about your limitations and your value—ask for role adjustments when needed.
Culture shift
Checking egos at the door isn’t weakness—it’s how...
Bubbles Everywhere: Cavitation and the Cooling System [E220]
2026/01/21
Thanks to our Partner, Pico Technology
Watch Full Video Episode
Matt goes down a rabbit hole on the science of bubbles and comes back with something surprisingly practical: cavitation is a major source of cooling-system component damage, especially in and around water pumps. The “bad guy” isn’t the bubble forming—it’s the bubble collapsing, releasing intense localized energy, micro-jetting, and shock waves that pit and erode metal surfaces over time. The takeaway: approach cooling-system maintenance as anti-cavitation prevention, not just “keep it from overheating.”
Key topics covered
Why cavitation damage is often misattributed to electrolysis (and what’s actually happening)
The real destruction mechanism:
Bubble collapse → extreme localized heat (doesn’t “cook” the system, but signals energy density)Micro-jet stream through the collapsing bubble “donut” → pitting/erosionShock wave effects (ties into why ultrasonic cleaning works)
How bubbles form even in a pressurized cooling system
Localized low-pressure zones behind an impeller bladePressure drops along surfaces and restrictions (design or contamination-caused)
Why “radiator cap” is a misleading name
Better term: degassing capIt maintains system pressure (key to preventing local boiling) and “burps” gas/vapor out
Coolant chemistry isn’t just freeze/boil protection
The inhibitor package forms a protective barrier on internal surfaces that absorbs cavitation attackOver time that protection depletes → cavitation damage shows up
Water quality matters more than most people think
Minerals/impurities can create deposits → restrictions → pressure drop zones → bubblesContamination can also become nucleation points for bubble formationDistilled/RO water or properly formulated premix is the safer play
“Universal coolant” skepticism
Use proper coolant type for the application—chemistry and inhibitor packages matter
Practical takeaways for shops
Start treating cooling-system service as evidence-based prevention
Testing and inspection that should be part of regular maintenance:
Degassing cap pressure test (rated pressure matters)Coolant concentration (ideally with a refractometer/hydro refractometer)li...
Common Cause and Special Cause [E219]
2026/01/14
Thanks to our Partner, Pico Technology
Watch Full Video Episode
Comebacks. Rechecks. Catastrophic parts failures. The stuff that makes everyone’s stomach drop. Matt makes the case that a big part of management’s day-to-day job is not “policing people,” but acting like an investigator—leading with genuine curiosity to figure out what actually happened and what should change.
Using Dr. W. Edwards Deming’s framework, Matt breaks problems into two buckets:
Common cause: Variation that’s built into the system (processes, tools, training, information flow, software, vendors, documentation, workflow chaos, etc.). These problems are repeatable—and if you don’t change the system, they’ll happen again.Special cause: A true one-off—rare, hard to predict, not systemic. Sometimes the correct response is support, not a giant policy overhaul.
The goal: build trust, reduce fear, and improve the shop over time through “constancy of purpose”—not knee-jerk blame.
Key Talking Points & Takeaways
1) Management’s role when things go wrong
Be an investigator, not a prosecutor.Start with: What happened? Why did it happen? What made it easier to fail than succeed?
2) Deming’s lens: common cause vs. special cause
Most problems are common-cause (system-driven), not “someone screwed up.”Mislabeling causes creates chaos:Treating common-cause problems like special-cause ones = scapegoating, fear, repeated failures.Treating special-cause problems like common-cause ones = overcorrecting, unnecessary rules, wasted effort.
3) Examples of common-cause “system” failures (shop edition)
Torque wrench out of calibration.Scan tool software out of date / tooling gaps.No real shop management system (handwritten tickets, misreads, manual re-entry).Process interruptions / constant context switching.Cheap unknown parts sources creating avoidable risk.Lack of SOPs, training, or accessible info.
4) What a real special-cause looks like
A normally reliable part fails unexpectedly (the one “bad water pump” out of hundreds).A rare freak mistake by a trusted specialist with no obvious systemic trigger.Response: support the person, document it, monitor trends—don’t build policy off a unicorn.
5) The trust factor

The Part-Time Performer (And The Full-Time Lesson) [218]
2026/01/07
Thanks to our Partner, Pico Technology
Watch Full Video Episode
This episode uses professional wrestling’s “part-time performer” phenomenon—stars who leave, come back, and instantly get the spotlight—to explore something that happens in auto repair, too:
When a specialist has a reputation that brings cars through the door, the right move is to lean into it—not resent it.
Key Talking Points & Takeaways
1) The Seth Rollins Quote Sets the Tone
“If you’re not learning, then you’re stagnant… and the business isn’t progressing.”Matt frames growth as a requirement—not a nice-to-have—for both the individual specialist and the shop.
2) Wrestling 101: “Protecting the Business” vs. “Understanding the Draw”
Matt revisits early WrestleMania and the idea of kayfabe (protecting the illusion) to explain a bigger concept:
The “outsider celebrity” (like Mr. T back then) wasn’t about pride—it was about bringing eyes and money.Selling offense (“selling” = making it look like it hurts) is part of making the other person look legitimate.
3) The Modern Version: The Part-Time Star Problem
Matt runs through the familiar cycle:
A star goes to Hollywood or appears occasionally (Rock, Cena, Undertaker, Lesnar, Goldberg).They return and get major wins/titles.The full-time grinders feel slighted—until they see the business reason:Those names are draws. Draws bring revenue.
4) The Auto Repair Translation: The Specialist Who Brings Work In
Here’s the pivot:
In shops, you sometimes have that person:the alignment specialistthe drivability/diagnostics specialistthe transmission/differential rebuilderthe ADAS/calibration personthe accessory/TPMS/trailer/camper personCustomers don’t just ask for the shop… they ask for that specialist by name.Matt’s point: Don’t let ego or envy sabotage something that helps everyone.
5) “Lean Into It” (Instead of Getting Weird About It)
Matt argues you should:
Promote that specialist more, not less.Treat their reputation as an asset to the entire shop.Recognize what it actually
A Lesson from Parkway Drive: Diamonds That Choose to Stay Coal [217]

Episode summary
Matt Fanslow pulls a lesson from an unexpected place: a Parkway Drive studio story involving Killswitch Engage’s Adam D. The band tried to force a new sound—clean vocals mixed with screams—and it just wasn’t working. The fix? Stop trying to be a different band and lean into what already fits.
Matt ties that directly into shop life: not every shop needs to work on every vehicle type or take every job, and not every person needs to be great at every kind of work. Whether it’s building around strong mechanical specialists, strong technical specialists, or choosing a narrower service lane, specializing on purpose can be the difference between surviving and thriving.
What you’ll hear in this episode
Why the “do everything” mindset can quietly punish shops (and people)A real example of pivoting back to core strengths (and winning bigger because of it)The difference between mechanical specialists and technical specialists—and why both are hard to findWhy “I can buy the tools” doesn’t automatically equal “we can do the work well”Checking ego at the door: success doesn’t require being everything to everyoneA nod to “reverse benchmarking”: build your identity around what others don’t do well
Key takeaways (shop + career)
Specialization isn’t weakness. It can be the most rational way to deliver consistent quality.Tools and information don’t replace capability. They support it—if the people and processes are there.Staffing reality matters. If you don’t have the right mechanical specialist or technical specialist, forcing the work in-house can be painful.You can evolve later. Being “not that shop” today doesn’t mean “never”—it can mean “not yet.”Identity beats imitation. Trying to match someone else’s “genre” can pull you away from what you’re actually great at.

What is the Most Misunderstood Concept in Auto Repair? And More: December 2025 Mailbag [E216]
2025/12/24

Watch Full Video Episode
Matt digs into listener-submitted questions—starting with a deceptively simple one that “freaks him out”: what’s the most misunderstood concept in auto repair? From there, the episode becomes a guided tour through the gray area between knowing what’s true and knowing what’s useful.
He revisits a frequent offender in the misinformation world: catalytic converter diagnostics, particularly the old “switch rate” concept, and why it’s fundamentally flawed, even when it appears convincing on a scan tool. From there, Matt zooms out into bigger “how-the-universe-works” territory—magnetism, electric fields, and why some of the most fascinating truths about energy flow will probably never help you fix a car (but are still worth thinking about).
The back half of the episode shifts into personal updates (family health), a few fun holiday questions (favorite Christmas movies), an unexpectedly intense movie rant (Thor’s Endgame arc), and a grounded-but-honest take on the future of EVs and hybrids.
Topics Covered
The hardest balance in teaching and learning: accuracy vs. applicabilityWhy most misinformation in training/resources is usually unintentionalCatalytic converter misconceptions:Why “post-cat O2 switch rate” is a bad diagnostic foundationWhy scan tool graphs can mislead you even when they “look right”What really matters before condemning a converter (fuel control, exhaust leaks, sensor accuracy, updates, airflow modeling inputs)Why OEM catalyst monitoring relies on oxygen storage capacity (OSC)—and why it’s not the same as true conversion efficiencyA brief detour into physics for the curious:Magnetism as an effect tied to moving charge (and why special relativity can explain part of it)The “energy comes from the field” idea—and why it’s fascinating even if it doesn’t help bay workEGR follow-up: throttling losses, flame speed, and thermal efficiencyPersonal Q&A: updates on Matt’s dad’s recovery and implanted defibrillator; Danielle’s long recovery arcHoliday lightning round: favorite Christmas moviesMovie plot that frustrates Matt most: Thor from Ragnarok → Endgame (and why “Fat Thor” was mishandled)EV future: energy density limits, why hybrids may remain the practical middle ground, and where hydrogen might fit
Key Takeaways
“What looks true” on a scan tool isn’t always what the monitor is actually judging.Catalyst diagnostics are more systems-based...

Watch Full Video Episode
In this episode, Matt shares a post he wrote after seeing yet another wave of “Who’s the most affordable?” questions in a local community group. He breaks down the hidden cost of chasing the lowest price, explains the local multiplier effect, and uses behavioral economics and game theory to show why short-term savings can create long-term pain—especially in auto repair. Matt also makes the case for educating employees on how small businesses really work, why ethical profit matters, and how small choices can preserve local options for your future self.
Key themes
Why “most affordable” has become the default question in local recommendation threadsThe idea that every purchase has two prices: the invoice amount and the impact on the local systemLocal businesses as a “local multiplier”: wages, suppliers, sponsorships, taxes, and reinvestment staying nearbyThe trap of short-term savings: hyperbolic discounting, loss leaders, and loss aversionAuto repair reality check: low prices can shift costs into warranty travel, time loss, and future headachesGame theory framing: a repeated prisoner’s dilemma—individual “defections” (price-chasing) add up to fewer local optionsThe skilled-trade value problem: cars depreciate while homes/buildings appreciate, shaping perceived worth of the work“Profits aren’t evil”: ethical profit as doing what you said you’d do, for what you said you’d do it forThe case for educating employees on business economics so they understand pricing, margins, and sustainabilityPractical compassion: offering to cover card swipe fees and understanding why local goods can cost more
Memorable lines
“Every purchase has two prices: the number on the invoice, and the impact on the system you live inside.”“The long-term consequences are invisible… until they’re painful and hard to reverse.”“Time—by far our most valuable asset.”“Residents and local businesses behave a lot like a repeated prisoner’s dilemma.”“Profits aren’t evil. I believe in ethical profit.”
Audience takeaway
If you always optimize for the cheapest option, you may “win” today but collectively lose tomorrow: fewer trusted local providers, fewer skilled jobs, and less community resilience—especially in specialized services like auto repair.

Watch Full Video Episode
In this episode, Matt shares a personal Thanksgiving story that turned into a real medical emergency. A long-time family friend suddenly becomes unresponsive at the dinner table, and Matt walks through the moment he had to decide whether to act, despite not being “formally” current on CPR.
He talks candidly about what it felt like to drag her to the floor, check for breathing, make the call to start chest compressions, hear ribs crack—and then watch her come back. From there, he connects the experience to life in an automotive shop: CPR and first-aid readiness, AEDs, fire extinguishers, panic, freezing, and why “somebody will know what to do” is not a plan.
It’s a conversation about preparedness, stress, and how our greatest weapon really is the thought we choose when everything suddenly goes sideways.
Episode Highlights
Opening with the quote: “Our greatest weapon against stress is our ability to choose one thought over another.”
Matt fighting a cold and joking about his “Nat King Cole” voice.
Thanksgiving at his parents’ house: Family and close friends gathered, including a 75-year-old family friend (“Jane”) who’s been part of the family’s holidays for years.
Jane says she’s really dizzy; Matt gets up to escort her to the living room.Her chin suddenly drops to her chest, she becomes unresponsive, cold, and clammy.The decision point:Matt checks for airway, tries to feel for a pulse, listens for breathing—only hears gurgling.Admits he doesn’t fully trust his own ability to feel a pulse with his heart pounding.The mental calculus: If you can’t be sure, what else is there to do but chest compressions?
Starting chest compressions:
Dragging her to the floor and focusing completely on her while the rest of the room “disappears.”Locking his elbows, using the beat of “Stayin’ Alive” as a guide.First compression: feeling and hearing the sternum/ribs crack—and taking that as feedback that he’s at the right depth.Before the second compression, her eyes fly open and she lets out a sound.
The immediate emotional whiplash:
First feeling isn’t relief, but anger and self-doubt: “Did I just overreact?” “Did I crack her ribs for nothing?” “Was this some dramatic hero move I didn’t need to make?”Reorienting to the reality that she was unresponsive and now is awake, talking, and oriented.

No Spoon: Breaking the Matrix [E213]
2025/12/03
Thanks to our Partner, NAPA Autotech Training and Pico Technology
Watch Full Video Episode
In this episode, Matt uses The Matrix—especially the line “there is no spoon”—as a metaphor for the invisible cages we build in our own minds. He connects the film to social constructs, substance use disorder, self-limiting beliefs, and the hard, messy reality of change.
Matt unpacks what it really means to “take the red pill”: leaving the comfort of your personal matrix, enduring an initial season of discomfort or even suffering, and slowly rebuilding your ability to cope, grow, and demand better—from yourself, your relationships, and your career.
Key Topics Covered
“There is no spoon” and social constructs
The Matrix as a metaphor for our personal belief systems, not just a sci-fi simulation.How ideas like “I can’t,” “they won’t let me,” and “this is just how it is” form our own private matrix.Money as a clear example of a social construct: it only works because we all agree it has value.
Substance use disorder & the red/blue pill choice
Reframing the Matrix pods and simulation as a stand-in for addiction and coping mechanisms.Drugs (or other coping tools) as a “cure” that works incredibly well… until the bill comes due.The “red pill” as the decision to leave a destructive coping mechanism and face reality.Why life often gets worse at first when someone chooses recovery—gray, flat, painful—before it gets better.
Atrophy, discomfort, and rebuilding capacity
Neo’s physical atrophy as a metaphor for emotional and coping atrophy after long-term use.Many people aren’t using to “get high” anymore—they’re using just to feel normal.Relearning how to feel feelings at full intensity without a chemical buffer.
Self-imposed limits and hidden capacity
The Matrix training scenes: bending the rules as a metaphor for challenging self-imposed limits.The “70% wall” idea from Navy SEAL training—quitting when there’s still gas left in the tank.How often we defeat ourselves before we even truly try.
The Kung Fu (David Carradine) lesson
Flashback scene with the “acid pool” that turns out to be water.Believing in the danger so completely that you fail before you start.How often we do the same thing with exams, careers, and life decisions.
Technicians, tests, and career ceilings
“I’ll never pass A6” / “I’ll never get that cert” as a self-fulfilling prophecy.Questioning whether your limits are real, or chosen.Practical self-inquiry: What can I do to change this belief? What actions can I take?
Relationships, work, and what we tolerate
Staying in unhealthy relationships (romantic, friends, employers, clients) because “this is the best I can do.”Starting with your own role: being a better spouse, friend, or employee and expecting better treatment in return.The trap where employers say, “If they acted like good employees, I’d treat them well,” and employees say, “If they treated me well, I’d act like a good employee”—and nothing changes.
Dutch Silverstein’s perspective
It’s important to treat people the way you want to be treated.But for sure: never treat someone the way you don’t want to be treated.
Taking the red pill in real life
The “red pill” as a choice, not a daily supplement.Expecting the initial result of that choice to feel worse before it feels...
Stop Searching, Start Becoming: The Right Shop Philosophy [E112]
2025/11/26
Thanks to our Partner, NAPA Autotech Training and Pico Technology
Watch Full Video Episode
In this episode, Matt takes a relationship quote and flips it into a perspective shift for shop owners, managers, and specialists: instead of obsessing over “finding the right” customers, employees, or employers, focus on becoming the right shop and the right person—over and over again. He explores how this mindset applies to attracting younger clients, building a place top technical and mechanical specialists want to work, and evolving with changes like EVs, culture, and work–life balance.
Key Talking Points
The quote that kicked it off:
“Love isn’t about fate and magic bracelets and destiny. It’s about finding someone you can stand to be around for 10 minutes at a time,” and the idea that it’s less about finding the one and more about becoming the right one again and again.
Translating relationship advice into shop life:
Stop fixating on “finding the right clients,” “the right shop,” “the right boss,” or “the right employee.”Shift the focus to becoming the right shop, manager, owner, or employee.
Becoming the right shop for your current and future clients:
Many shops are currently tailored to an older clientele (boomers) and have great rapport with them.Younger clients often care deeply about your why—your purpose, values, and what you stand for.Start projecting an image and message that resonates with the clients you’ll need in the future, not just the ones you serve today.
Becoming the right employer:
Think about the types of technical specialists and mechanical specialists you’d love to attract.What are they after now, and what will they value most in the near future (purpose, time off, culture, tools, training, environment)?Make tangible changes in the shop that align with those values and make sure those changes are visible.
Creative ways to “show, not tell” as an employer:
Hosting training classes in your shop so other shops’ staff and owners can see your facility.Letting others experience climate control, lighting, equipment, computers at every bay, etc.Letting your current team’s honest feedback become a powerful, organic recruiting message.
Culture vs. pure production:
As shops hit their production targets more consistently, culture starts to matter more.High-output but toxic people can drag down the overall environment.Sometimes the right fit is someone who might produce a little less but makes the team function better and reduces animosity.
What it means to be the right employee:
Contributing to ethical profit and strong production.Being a good teammate who doesn’t undermine the system.Helping with what the shop needs: clients, employees, reputation, and growth.Being able to demonstrate your value beyond hours billed—teamwork, leadership, culture.
Evolving with technology and the market (EV example):
Understanding your shop’s stance on EVs and being able to discuss it intelligently.Looking at the local EV car park, investment needs, safety, and training.Positioning the shop to succeed ethically and profitably as the car parc changes.
Seeing the shop as an ecosystem:
Front of house, back of house, management, and employees as symbiotic systems.Shared goals: profit, stability, and long-term perpetuation of

Watch Full Video Episode
In this episode of Diagnosing the Aftermarket A to Z, Matt Fanslow uses a famous Michael Jordan quote, a heartbreaking Minnesota Vikings loss, and a rant from Jeff Compton of The Jaded Mechanic Podcast to dig into a big question:
When did we get so impatient with young people—and what is it costing our industry?
Matt reflects on how we treat new, entry-level mechanical and technical specialists in our shops, how “common sense” isn’t actually common, and why our own backgrounds make it easy to forget what it’s like to start from zero. He draws parallels between sports, restaurants, and auto repair, and makes the case that if we want to “grow our own,” we must build patience and structure into our businesses.
Along the way, he talks about failure as a prerequisite for greatness—using Michael Jordan, Larry Bird, Muhammad Ali, and even win–loss records and batting averages to remind us that the “greats” failed a lot before anyone called them great.
Highlights & Topics Covered
Michael Jordan’s failure quote and what it really says about successA recent Vikings–Bears game:JJ McCarthy’s rough day, clutch fourth-quarter drive, andHow special teams and defense actually lost the gameThe internet meltdown: instant calls to replace a young quarterback who’s essentially still a rookieA short video rant from Jeff Compton (The Jaded Mechanic Podcast) about having patience with young peopleThe core question: When did we get so impatient—and were we always this way?Generational shifts in handling criticism, shame, and feedbackWhy “common sense” isn’t common:How background, upbringing, and exposure shape what feels obviousGrowing up around farms, equipment, and shops vs. growing up with screensHomemakers, latchkey kids, and how changing family structures change what kids bring into the workplaceThe reality of today’s entry-level hire:No mechanical backgroundDoesn’t know a hex from a Torx… yetThe shop’s responsibility if you want to “grow your own”:Structuring the business to shoulder an apprentice who isn’t producing much at firstDefining basic expectations (showing up, being on time, not repeating the same mistake endlessly)Skill decay and repetition:Lab scopes, training classes, and how fast proficiency fades without regular useHow we criticize: sharp scalpel vs. rusty spoon; cutting people apart vs. building them upRemembering that apprentices didn’t choose their childhood or start point—but are choosing this careerThe sports angle on failure and greatness:Michael Jordan getting cut from his high school teamPat Riley’s quote about last shot vs. “save my life” shot (MJ vs. Larry Bird)Muhammad Ali’s losses, UFC careers, and the obsession with “perfect records”Baseball batting averages: greatness at 30% successA teaser for a future episode: how this profession can play a role in the “war on young men”
Key Takeaways
Failure is part of greatness. The people we call “the greatest” in sports failed repeatedly. Expecting perfection from a first-year tech is delusional.
Common sense is built, not born. What feels obvious to you probably came from years of exposure, mistakes, and stories you grew up around. Your apprentice didn’t get that same download.
If you want to grow your own, structure for it. Shops that bring in entry-level mechanical/technical...

We unpack what “boundaries” actually are—and aren’t—in shops and life. Margaret draws clear lines between rules vs. boundaries, protective vs. containing boundaries, and gives scripts you can use with customers, colleagues, and leadership. Matt adds his trademark honesty (and jokes) about self-regulation, “saying it like it is,” and swapping “but” for “and.”

Key ideas & takeaways
Rules vs. Boundaries:
Rule: “You’re not allowed to yell at me.” (trying to control others)Boundary: “If you yell at me, I will leave the room.” (what I will do)
Two Types of Boundaries:
Protective: Guard yourself from others’ behavior (leave the room, pause the call).Containing: Guard others from your behavior (take a break before you escalate).
Simple Shop Scripts
Advisor to escalated customer: “I’m happy to help and if the yelling continues, I’ll have to ask you to leave. I’m happy to help when we’re calm.”Advisor protecting self: “If voices rise, I’m going to step to the break room for five minutes and then return to help.”Employee to manager (after-hours texts): “I’ll handle this when I’m back at work.” (Boundary = your response, not their texting.)
Use “and,” not “but.”
“I hear you overslept and I need you here on time.”Removes the “disqualifier” feel of but, holds two truths at once, reduces power struggles.
Broken-record technique for heat
Repeat your boundary + offer: “I’m happy to help, and if the yelling continues, I’ll need you to leave.”
Professionalism ≠ light switch
Containment and communication are skills that need coaching, not just warnings. Managers can (and should) teach, not only discipline.
Reasonable Expectations
Some things are rules of employment (e.g., start times). People can be upset and the expectation still stands.
Curiosity First
Lead with, “Are you open to feedback?” “Tell me what would work better.” You can hear it without agreeing to change your decision.
Culture Over Chaos
We don’t need reality-TV drama in a professional shop. Boundaries + coaching = fewer blowups, better results.
Practical Playbook - Train mechanical specialists and technical specialists to:
Spot their escalation early (breathing break, lap around the building).State boundaries in first-person (“I will…”) not second-person commandments.Swap but → and in feedback and estimates.
Train advisors on three phrases:
“I want to help, and we’ll...

Matt Fanslow opens with “Resistance is futile” and tackles a common belief: “Resistance always makes current go down.” He walks through why that’s mostly—but not always—true, and shows how electric motors (especially starters) can draw more current when unwanted resistance slows them down by reducing counter-EMF. Along the way he ties Ohm’s Law to real diagnostics, shares a Rust Belt cable-smoker story, and closes with a heartfelt reminder about seeking help for the “stuff” we all carry.
Key Topics
The “always/never” trap in electrical claimsOhm’s Law in real life: fixed voltage vs. changing conditionsWhy motors misbehave: counter-EMF as dynamic “resistance”Starter example: inrush current, RPM drop → current riseHigh-resistance cables that increase current (and make heat)Where the energy goes: heat in brushes/cables vs. mechanical workInstantaneous truth of Ohm’s Law: accurate at a moment in time, not across changing dynamicsPractical tell-tales: slow crank + rising amps + hot/smoking cablesMental health note: removing stigma and getting professional help
Practical Takeaways
Motors are dynamic loads. If RPM drops (binding, poor supply, worn pump), counter-EMF falls and current can increase even as “resistance in the circuit” rises.Heat = the clue. Elevated current with slow rotation often means energy’s being dumped as heat (cables glowing, insulation softening, brushes cooking).Measure what matters. Combine voltage drop, current measurement, and temperature/thermal observation under load to find where the power is going.Interpret Ohm’s Law correctly. It holds at an instant; across changing conditions, re-evaluate with the values at that moment.
Case Study Highlight
Chevy Suburban (late ’80s/early ’90s): Slow crank, ~400 A draw when ~150 A expected; braided negative cable glows red under a 10–20 s crank. Root cause: high-resistance path + reduced counter-EMF → higher current and wasted power as heat.
Tools & Concepts Mentioned
Current probe / ammeterVoltage drop testingStarter relative compression patternsCounter-EMF (a.k.a. back-EMF)Old-school VAT-style analyzer (Snap-on digital variant)
Quotes / Moments
“It’s rare we can say always or never.”“Ohm’s Law isn’t broken—it’s instantaneous.”“If it isn’t turning it into work, it’s turning it into heat.”

Matt riffs on a surprisingly quiet moment from Rocky—the late-night scene where Rocky admits he can’t beat Apollo and Adrian simply asks, “What do we do?” From that question, Matt draws a blueprint for technicians and shop owners: set realistic, self-assigned wins and stack them. Instead of living and dying by big, binary outcomes (“fixed/not fixed,” “hit benchmark/missed benchmark”), build momentum with attainable goals that compound into competence, confidence, and better shop results.
Big Ideas
“What do we do?” beats “You can do it!” Swapping empty hype for practical next steps creates traction.Redefine winning: Rocky doesn’t win the fight; he wins by “going the distance.” Translate that to your day: hit achievable targets that move you forward.Stack small, durable improvements: The path to 40+ billed hours or top-quartile shop productivity runs through many smaller, consistent wins.Perfection limits joy: Ambition is good; impossible standards starve you of pride and progress.Benchmarks aren’t commandments: Continuous improvement may matter more than someone else’s KPI.
Practical Takeaways for Techs
Scope reps, not scope heroics: Use the oscilloscope on easy cars and routine checks—pair voltage with time until it’s second nature, then add a second channel and a low-amp probe where it makes sense.Thermal imager habits: Pull it out on brake inspections, wheel-bearing complaints, and on known-good vehicles to calibrate your eye for “normal.”Micro-goals to build hours: If you’re billing ~20 hrs/week, aim for 25 (≈+1 hr/day). Then 30. Ask: Where can I reclaim two hours? (economy of motion, fewer tool trips, better setup).
Practical Takeaways for Shop Owners/Leads
Aim for +10–15% improvements first: If techs are ~60% productive, target 70%, not 100% overnight. Design the system to enable the next step.Design wins into the week: Encourage daily scope/thermal reps, short debriefs, and “wins boards” that recognize process improvements—not just hero fixes.Coach with the Adrian question: When someone says, “I can’t hit that,” respond with: “What do we do?” Identify the next two concrete actions.
Memorable Lines
“We can define our own successes—it doesn’t have to be everyone else’s.”“Set wins somewhere earlier in the process, not only at the final repair.”“I hope you’re proud of yourself—and that you let yourself feel it.”
