Thought I had a transmission issue, but Trans Medic diagnosed it as an engine misfire—saving me big. Mike explained everything, gave part suggestions & sent me off with no charge. Honest, knowledgeable & highly recommended!
Gary R.
Took my Nissan Frontier to Trans Medic for a clunk noise. Initially told it needed a full rebuild, but a simple torque converter fix was done free of charge. Honest & reliable service!
Joshua P.
Got my 2005 Explorer fixed at Trans Medic—solenoid and torque converter replaced in under a week. My buddy’s engine was rebuilt there, too. Cars are running great—best in town and reliable service!

Communication was great during the whole process, truck was fixed in more than a timely manner. 2 year warranty was the selling point for me. 5 🌟

After a subpar rebuild, Trans Medic installed an upgraded 68RFE transmission overnight—delivering dramatic performance, reliability, and quick turnaround. Highly recommend Nash and his team!

Came in for a transmission service just to get fluids changed and make sure everything is up-to-date. He’s straightforward. I came in and told him what I needed. He did it. I had the truck the next day. It was ready day of, however. He was Professional and I will definitely be coming back.

Amazing! Great service, honest, friendly, have already referred people.

Dropped my truck off last week on Friday to put a new built up 48re in it. They were very prompt and accurate on their timeline and the service was excellent. I hope I don’t need much transmission work in the future but if I do I will totally be using Mike and the guys at Trans Medic. Thank you guys!

My stepdad introduced me to this shop 25 years ago. I had a positive experience then and have over and over throughout the years.
Today I picked up my truck from repair and it either had dead battery's or faulting glow plugs. It took some time to get it started but the guys in the shop stuck with me in helping getting it started. Even going as far as adding oil at no charge to make sure it had the right engine pressure to start as it's a diesel. Could not be more impressed, appreciative and willing to refer them to anyone I know.
Cindy M.
They worked on our small motorhome transmission and everything was great. Super nice people to work with and a fair price for transmission rebuild. Work was completed in a timely manner as well. We highly recommend transmedic in Gresham for your transmission needs.
Beth W.
I was refered to this shop when I got some not so great advice from a different mechanic and I'm so happy that I did. They were kind and explained the whole process and got my jeep in and out within the day. Can't recommend them enough!
Chris C.
Nash is honest, personable, and responsive. After a minor pan issue and some miscommunication, he personally set things right. He explained the transmission replacement and upgrades on my 2016 Ram 2500. Trans Medic stands by their work.

Trans Medic showed their knowledge, expertise, craftsmanship along with honest open communications in providing me with a superb experience. The price was right and upon completion I was able to make an uneventful 4 hour drive back to Seattle from Portland. There isn’t a better tranny shop in my opinion. Thanks Trans Medic Transmissions for doing a superb job!! Glen

Larry F.
2 cars 2 transmissions best service ever had in my life. The staff was very professional. They give you a quote and a timeline and for the most part stick with it Unless they run into parts they have a problem getting. I was referred to transmedic through a friend of mine and I would not hesitate to refer a friend of mine. Thank you very much Transmedic.
Marpa M.
I had been fighting my car for months trying to figure out the issue. I finally narrowed it down to the transmission, so i tried this place out. Absolutely fantastic work!! I ended up needing it rebuilt, which is what I had initially assumed. They were upfront about costs and timeline and it ended up way cheaper and faster than expected! Definitely check these guys out!
Alex V.
From the beginning transmedic was easy to get a hold of and very communicative. I called them on a Wednesday, dropped the vehicle off on a Thursday, and got our truck back by Monday morning! The transmission shifts great, the price was beyond fair, and I got a product better than the original.
