Who we are

Dayton's trusted source for transmission service and repair, PLUS complete automotive service, for over 15 years. Ken Shirly, owner and operator, is a transmission expert. His staff is experienced and trained to handle all of your vehicle's needs.

Why choose us?

Transmission repair is one of the biggest expenses you'll encounter with your vehicle, and one of the most complex. And engines, suspensions, brakes and everything else? Let's be honest, automotive repair isn't cheap. You need service you can trust.

We Are Trustworthy

You need an honest and trustworthy mechanic. One who will give you sound advice, truthful opinions, and a fair and reasonable price. You deserve reliable and reasonable transmission and automotive service.

That's why you should call Transmissions Plus.

Transmission Experts

We have decades of experience repairing car and truck transmissions. It's our specialty! Our staff are experts in servicing and repairing automatic transmissions and transfer cases, as well as manual transmissions. Foreign and domestic vehicles are welcome. Cars and trucks with all drive types: rear, front, all or four wheel.

In order to provide the best possible service and warranty, we prefer to manage the entire process. We will pull the unit, performing the necessary service or repair or replacement, and reinstall it. Not only does this produce the best possible result, it can also save you a lot of hassle and, in the long run, money.

Of course, if you've already pulled your tranny or picked up a used one, we are happy to rebuild it for you, swap it out or install it. We will do whatever we can to help.

Car & Truck Service

Transmissions Plus does more than just transmission repair. We also perform all types of car and truck repairs. Engines and engine components, brakes, suspensions and so forth. Plus routine maintenance such as tune ups, oil changes, coolant flush, a/c service, etc. We do it all. No matter what type of service or repair you need, we can probably handle it and get you back on the road.

Do you have something else that has a motor, maybe some wheels, etc? Bring it in! We'll have a look and tell you honestly if we can help, and if we can't, we might know someone who can.
