Description
Automotive Field Theory explores the forces that shape automotive repair, including the ones measured with a meter or oscilloscope and the ones that cannot be found on a wiring diagram.
Hosted by automotive diagnostic specialist, shop manager, and instructor Matt Fanslow, the podcast begins in the automotive aftermarket but rarely stays inside its traditional boundaries. Diagnostics, electricity, technology, leadership, psychology, economics, game theory, history, music, movies, family, and human behavior may appear unrelated. Look closely enough, however, and connections begin to emerge.
A vehicle may arrive with a technical fault, but the work surrounding it is rarely technical alone.
Information is incomplete.
People make decisions under pressure and uncertainty. Incentives shape behavior. Standards gradually drift. Good intentions produce unexpected results. The official process may say one thing while the system quietly rewards another.
Automotive Field Theory is an attempt to understand those interactions.
Drawing from real diagnostic work, shop management, industry conversations, personal experience, and an occasionally inconvenient level of curiosity, Matt examines not only how things work, but why they work that way, how they became what they are, and what apparently unrelated subjects might teach us about repairing vehicles, leading people, running businesses, and improving the automotive industry.
Some episodes begin with a failed component. Others begin with Metallica, quantum physics, professional wrestling, a historical disaster, a round of golf, or a question that refuses to leave Matt alone.
Eventually, they all enter the same field.

Thanks to our partners Promotive, WickedFile, and OverdryveShould the employee who helped grow your shop pay the same price as a stranger? If profits double because the owner hired a new marketing company, who gets the credit? And what happens when the agreed price triples the day an attorney looks at it?Recorded live at AAPEX in Las Vegas, Hunt Demarest, CPA with Paar Melis & Associates, sits down with Matt Fanslow, diagnostic specialist, shop manager and host of Automotive Field Theory, to talk about sweat equity and selling a shop to a key employee. Fourteen years ago, Matt joined a three-person shop and begged the owner for one month running the front counter. That month changed the business. He later told his boss he worried about building a shop he could never afford to buy. Today, that question is on the table.Hunt explains why handshake succession deals go wrong: nothing gets written down, and each side pictures a deal the other never agreed to. He covers why a fair deal leaves both people a little unhappy and why fewer key employees are buying shops as outside buyers pay more. He also shows why payment terms matter more than price. If the shop brings in $60,000 and the payment is $50,000, the deal works. At $30,000, no price will fix it. Paying a retiring parent a salary sends a big share of the money to payroll taxes, and a better structure can cut the buyer’s cost in half. Matt closes with the parable of two sisters and an orange: ask what the other person needs, and a 50/50 split can give both sides everything they came for.Whether you’re the owner planning your exit or the right-hand person who helped build the place, this episode will help you start the conversation before it gets harder to have.What You'll Learn…00:00 Intro03:05 Insider price vs. outsider price05:32 Why handshake deals fall apart06:32 One month to prove it11:07 Why a fair deal feels unfair16:40 Fewer key employees are buying23:26 Who earned the growth?25:23 The attorney who tripled the price26:53 The cash flow test31:06 Why paying dad a salary backfires33:50 Two sisters and an orange35:02 Why 53/47 beats 50/50If you’re ready to find out what your key employee really expects, test whether your shop’s cash flow can support a buyout, and have the succession talk before it turns into a standoff, this episode is essential listening.Matt Fanslow, Diagnostic Specialist and Shop Manager at Riverside Automotive, Red Wing, MN (https://www.riverside-automotive.com/)Podcast Name: Automotive Field TheoryWebsite: https://mattfanslow.captivate.fm/YouTube: https://www.youtube.com/@automotivefieldtheoryFacebook: https://www.facebook.com/AutomotiveFieldTheory/Spotify: https://open.spotify.com/show/0asT3Cu6Df5hCbkuabVXLuApple: https://podcasts.apple.com/us/podcast/automotive-field-theory/id1591616103Thanks to our partner, PromotivePromotive has over 40 years of recruiting and automotive experience.

Watch Full Video EpisodeContent advisory: This episode discusses child sexual exploitation, coercion, self-harm, animal abuse, and suicide. It contains strong language.We give our kids access to the internet. But how often do we stop to consider that we’re also giving the internet access to our kids?In this episode of Automotive Field Theory, Matt Fanslow steps outside automotive diagnostics to address a threat every parent, caregiver, and educator should understand: 764 and other violent online networks targeting children.What began as research into online scams became a deeply personal discussion about grooming, sextortion, fear, and control. The FBI has warned that these networks manipulate victims into increasingly harmful behavior, with motivations that can include status, belonging, sexual gratification, and a desire to cause chaos.Matt discusses how an online friendship can become a trap, why embarrassment and fear can keep children silent, and why a strong relationship with your child still needs ongoing conversations about online safety.The message is straightforward: learn about the threat, pay attention, and make asking for help feel safe. If your child comes to you frightened, your response matters. As Matt puts it: “You’re flying the plane. Fly the damn airplane.”In This EpisodeHow Matt’s research into scams led him to 764.Financial sextortion and exploitation driven by control and harm.How predators use gaming, social media, and messaging platforms to establish trust.Why shame, threats, and fear of disappointing parents can prevent disclosure.The role of parental involvement, monitoring, and honest conversations.Recognizing changes in behavior that deserve a calm, caring check-in.Why awareness needs to extend to schools and communities.Making sure children know they can ask for help, even after something has happened.Resources and ReportingFBI: Understanding 764 and other violent online networks: Official information about targeting, coercion, and warning signs.NCMEC: Sextortion guidance: Help for victims and caregivers. Preserve messages and account information; do not delete evidence. The person exploiting the child is responsible for the abuse.NCMEC CyberTipline: Report suspected child sexual exploitation.Take It Down: A free service that can help limit the spread of nude or sexually explicit images taken before age 18 on participating platforms.FBI Tips: Report threats or suspected criminal activity. For immediate danger, call 911.A message for young people: You deserve help and protection. You do not have to handle threats alone.Share this episode with a parent, caregiver, educator, or anyone responsible for helping keep children safe.Thanks to our Partners, Pico Technology and AutelAre you chasing elusive automotive problems?

A routine software update on a 2021 Jeep Grand Cherokee turns into a diagnostic curveball when the drivetrain control module loses communication, then returns with new trouble codes and a calibration that won’t complete.Matt walks through the case, explains how a factory STAR case bulletin provided the missing information, and shares why access to original equipment service information can prevent unnecessary parts replacement.In This EpisodeDiagnosing a service four-wheel-drive message and DTC C1463-94, related to unexpected front axle disconnect operation.Losing communication with the drivetrain control module during a software update.Recovering communication and completing programming, only to encounter new codes and a failed calibration.Finding a factory STAR case bulletin addressing trouble codes that can appear after the update.Discovering an undefined transfer case classification value and locating the required code on the transfer case.Completing the classification programming, ECU reset, and calibration to resolve the issue.Recognizing how a difficult programming experience can make module replacement seem more justified than the evidence supports.Key TakeawaysNew trouble codes after programming don’t automatically mean a module has failed. Missing configuration information can create problems that require additional setup.Factory service information can fill critical gaps. In this case, Matt found the bulletin he needed in TechAuthority after it was unavailable in the aftermarket resource he checked.An inexpensive, readily available part can still be an unnecessary replacement. Checking the relevant service information helped Matt resolve the concern without replacing the drivetrain control module.Shops need a clear path to purchasing information. Matt encourages technicians and management to establish access to factory resources and track when those resources provide information missing elsewhere.Timestamped Topics00:23 — The Jeep case begins: Customer complaint, original fault code, software update, and loss of module communication.07:15 — New codes after programming: Failed calibration attempts lead to a search of factory service information and a relevant STAR case bulletin.13:37 — Completing the fix: Transfer case classification programming, ECU reset, successful calibration, and road test.19:24 — Information access and shop support: Preventing unnecessary repairs, funding factory information access, and documenting gaps in aftermarket resources.25:09 — Closing thoughts: How often does missing service information affect a diagnosis without anyone realizing it?Tools and Resources DiscussedwiTECH, TechAuthority, ALLDATA, a TOPDON battery maintainer, and factory STAR case bulletins. Matt also discusses GM Preliminary Information bulletins and Ford Special Service Messages as examples of additional diagnostic resources.This case describes one vehicle’s repair experience. Programming recovery and setup procedures vary by vehicle; consult the applicable factory instructions.Watch Full Video EpisodeThanks to our Partners, Pico Technology and AutelAre you chasing elusive automotive problems?

Modern automotive repair demands intelligence, creativity, and technical skill. So why does the old stereotype of the auto mechanic still linger?Inspired by the movie I.Q., Matt Fanslow examines how public perceptions of automotive careers affect technicians, parents, students, and the industry’s future. He discusses the growing need for specialists, the value of school outreach, and the responsibility shop owners share in helping people understand the profession.From career days to shop visits, Matt offers practical ways to showcase the problem solving behind vehicle repair and help the next generation see it as a career worth considering.Key TakeawaysChanging a job title only goes so far. Calling someone a technician or specialist means more when people understand the expertise the work requires.School outreach reaches parents, too. Career days, demonstrations, and job shadowing can challenge assumptions held by both students and adults.Shop owners can make participation easier. Supporting employees with paid time for outreach treats recruiting and industry advocacy as long-term investments.Show the work. Diagnostic waveforms, electrical testing, and major mechanical repairs can make the profession’s complexity visible.Stop downplaying the skill involved. Dismissing difficult work as something “anyone could do” undermines technicians and the profession.Put It Into PracticeConnect with a local school about a career day, classroom demonstration, or shop visit. Give students and parents a clear view of the work, and support the employees who help tell that story.Watch Full Video EpisodeThanks to our Partners, Pico Technology and AutelAre you chasing elusive automotive problems?

Watch Full Video EpisodeWhat happens when a customer decides to take their business elsewhere? Do you make it easy for them to leave, or do you make sure they never want to come back?In this episode of Automotive Field Theory, Matt Fanslow shares a frustrating experience switching internet service providers at Riverside Automotive. What started as a fairly straightforward decision to upgrade the shop's internet and phone service turned into an unexpected lesson in customer relationships, business strategy, and understanding the game we're actually playing.Along the way, Matt discusses the challenges of building a reliable shop network, the importance of upload speeds for modern automotive training and communication, and how a properly designed network helped solve years of connectivity problems.But the bigger question isn't about internet service. It's about what happens when a business takes a customer's decision to leave personally.How do we respond when a customer decides our repair estimate is too expensive? What happens when they choose another shop? Are we preserving the possibility of a future relationship, or are we so focused on the immediate transaction that we destroy it?Drawing on game theory and the concept of infinite games, Matt explores why the way we handle these situations can have consequences far beyond a single repair order.Topics discussed:Why Riverside Automotive switched from cable internet to fiberShop networking, Wi-Fi access points, and the value of reliable infrastructureHow a routine service cancellation became a lesson in poor customer relationsWhy customer retention isn't always about discounts or lower pricesHandling customers who choose a competing repair facilityThe difference between losing a transaction and losing a relationshipHow negative experiences influence word of mouth and future businessFinite versus infinite games and why the distinction matters in businessWhy the same principles apply to employees who decide to leaveThe bigger takeaway:Not every customer will stay. Not every estimate will be approved. Not every employee will spend their entire career with your business.But how you handle those departures can determine whether the relationship remains an opportunity or becomes a permanently closed door.In an infinite game, the objective isn't to win every transaction. It's to build a business capable of continuing to play.Connect with Matt:Have an episode idea or want to join the conversation?
