United Transmission is there for us with quality service, quickly and reliably. In one word, they are excellent!

Jorge R.

Maintenance Supervisor

We would not think of using anyone but UTX. When one of our trucks is down, we depend on them for reliable service. They have the experience and knowledge and do a great job for us. I can depend on – and trust – UTX to come through for us.

Peter J.

Fleet Manager

UTX gets the job done right, and quickly, so we can put the truck back on the road and it works. They have the expertise and helpfulness – that’s whey we’ve been using them for over 20 years.

Charlie H.

Head Mechanic

Donnie was stellar and awesome in helping my wife and myself diagnose our transmission issue. He helped me in a time of need and guided me in how to solve my problem. They offered me whatever I needed to fix my issue. I will never forget the customer service. Go to UTX if you can!
