Transmission internals on the bench

We tell you what’s
actually wrong.
Even when it’s less
than you were told.

Brakes, engines, diesel, transmissions and everything in between. We find out what’s actually wrong, then you decide what happens next.

What comes
through the bays

Full service shop. Diesel and transmissions are where we go deepest, but most of what rolls in here is everyday work.

Work underway on the lift

Nothing gets touched
until you say so.

How we
do business

The part most shops leave you to find out after they already have your keys.

You pay for the diagnosis, not the quote

Finding the actual fault takes a tech, a scanner and time on the lift, so there's a diagnostic fee for that. Once we know what's wrong, the estimate to repair it is free and you're not obligated to leave it here.

You get the number before we start

Written estimate, itemized. If we open it up and find something else, you get a phone call. Nothing gets added to your bill without you hearing about it first.

You pick the repair

Most problems have more than one fix at more than one price. We lay them out, tell you which one we'd do on our own vehicle, and then it's your call.

Bring us somebody else’s quote

We'll verify it either way. If they were right, we'll tell you they were right.

Anything else you want to know before you bring it in, just ask.

The shop

Who you're
handing the keys to

"I got tired of seeing people overpay for repairs and services they didn’t need.

I was born and raised in Clarksville and have spent 30 years in the automotive industry. Nine years ago, I opened A+ because I knew there was a better way to do things.

We’re a five-person shop, and that keeps it personal. Your vehicle isn’t another number in a huge service department. Every job gets the same care and attention.

I want you to leave knowing you were treated fairly, your vehicle was taken care of, and you’ve got a shop you can trust."

They did the work pretty quick. He fixed my oil leak, transmission fluid leak, and fixed my motor mount. Guy was very nice and communicative. He told me to come back the next week so he could check his own work free of charge. I will continue to use this shop in the future.

Best diesel mechanics in town! They fixed my AC, installed lift pump, Edge digital gauge, changed oil and rotated tires. Owner kept me updated every step of the way and even showed me how to use my new gauge to maximize performance.
I will never take my truck anywhere else!

Don't let the couple of bad reviews scare you away from this amazing shop. My transmission went out at only 90k miles. They not only helped me find a good deal on a gently used transmission, but they also repaired it within a week of my transmission being delivered. They did an amazing job and even checked for free 1 week later to make sure there wasn't leaks. They gave us the best quote and did the best job. My van is running better than before!!
