If you’ve run a transmission shop long enough, you’ve probably found yourself wearing more hats than you ever expected.

Some days you’re a builder. Other days, you’re a parts manager, service writer, salesperson, marketer, recruiter, accountant, or therapist. Most days, you’re all of them before lunch.

When I owned my shop, I took pride in that. I thought being involved in every detail was what made a successful owner. Looking back, I realize I spent too much time working in the business and not enough time working on it.

That’s not to say hard work is a mistake; it’s definitely not. But there are lessons I learned the hard way that I’d approach differently if I were opening a shop today.

Every Process Has a Cost

When most shop owners evaluate a job, they look at parts cost, labor hours, and profit margin. But what often gets overlooked is the cost of managing the process itself.

Take building transmissions in-house. You need a skilled builder, and good builders aren’t cheap. Then someone has to tear down the unit, identify the failure, source the parts, place the orders, track shipments, verify everything arrives correctly, and schedule the build around the work already on the bench. And every one of those steps takes time.

As owners, we tend to view that work as “just part of the business,” but it’s worth asking a simple question:

Would that time be better spent elsewhere?

The older I got as an owner, the more I realized that time and attention were just as valuable as money. Every hour spent managing a process is an hour that isn’t spent developing employees, improving customer relationships, building marketing programs, or planning for growth.

Being busy and being productive aren’t always the same thing.

Protect Your Mental Bandwidth

One thing nobody tells you about ownership is how difficult it can be to truly disconnect.

Picture this: you’re on vacation with your family or sitting in the stands watching your kid’s game. Your phone rings. It’s the shop.

A transmission that left last week is coming back.

Immediately, your mind starts racing.

How much is this going to cost? How many hours are we going to lose? What jobs are now delayed? What is the customer thinking?

It doesn’t matter whether you’re on a beach, at a ballgame, or sitting at the dinner table. Mentally, you’re right back at the shop.

That’s the part of ownership people don’t talk about enough.

The stress isn’t always tied to the dollars. It’s tied to the responsibility.

The more operational risk you personally carry, the harder it becomes to ever fully step away from the business.

As owners, we have to protect our mental bandwidth just like we protect our cash flow. If every issue requires your immediate attention, the business eventually starts owning you instead of the other way around.

Don’t Build Your Business Around Your Ego

This lesson took me the longest to learn.

Like a lot of transmission shop owners, I took pride in knowing everything. I wanted to know every common failure point, every update, every rebuild kit, every converter, and every part number. Being the transmission expert was part of my identity.

But if I were starting over, I’d spend less time proving I could do everything and more time asking whether I needed to.

Customers come to us because they trust us to solve a problem. They’re not evaluating whether we built the transmission ourselves, stocked every part in-house, or memorized every SKU in the catalog. They’re evaluating whether we fixed their vehicle and took care of them.

Sometimes I think shop owners confuse capability with necessity. Just because we’re capable of doing something ourselves doesn’t mean it’s the best use of our time, our people, or our resources.

That’s not a knock on craftsmanship. It’s a reminder that we’re running businesses, not just performing repairs.

What I’d Do Differently Today

If I opened another shop tomorrow, I’d build it around efficiency instead of tradition.

I would still build certain units in-house where it made sense. But I wouldn’t feel compelled to build everything.

I’d focus on creating systems that reduced complexity and made growth easier. I’d rely more heavily on trusted vendor partners. I’d carry less inventory. I’d simplify my operation. And I’d think much harder about hiring.

Finding talented transmission professionals has always been one of the biggest challenges in this industry. Finding general technicians is significantly easier.

Knowing what I know now, I’d create a model where a smaller number of transmission specialists support a larger group of technicians. That structure is easier to scale, easier to sustain, and often easier on the bottom line.

I’d probably add more general repair work as well to keep lifts productive and smooth out the peaks and valleys that every transmission-focused shop experiences.

Most importantly, I’d stop trying to be everything to everyone.

The Goal Isn’t More Work

One of the biggest traps shop owners fall into is believing that success means carrying more responsibility.

I’ve learned the opposite is often true.

The most successful owners I know aren’t necessarily the best builders or the smartest diagnosticians. They’re the people who have built businesses that don’t rely on them to solve every problem personally.

That’s what working on the shop looks like.

It’s creating systems. Building teams. Developing partnerships. Eliminating unnecessary stress. Making decisions that allow the business to grow without requiring more of your time every year.

If I could give one piece of advice to my younger self, it would be this:

Your time is your most valuable asset. Spend it where it creates the most value.

Because at the end of the day, the goal isn’t just to build transmissions. It’s to build a business that gives you the freedom to enjoy the life you’re working so hard to create.
