Marsh Transmission

Paul was awesome and the staff is extremely friendly. Super knowledgeable, trustworthy and helpful. They put my mind at ease. Don’t think I’ve ever given an automotive shop 5 stars in my life. Truly deserved!

Amazing service and more than accommodating. My Silverado had a stutter while driving and I had it checked over by the dealer I purchased it from and they said I needed a whole transmission. They quoted me $6500 and shoved me out the door without another question answered. Then on thanksgiving week I dropped my truck off at Marsh (who I had originally taken my Ranger to) and even with the holiday they took amazing care of me and my truck. Good service is incredibly hard to find these days and I’m beyond happy! I cannot thank y'all enough!

A mechanic friend recommended that we try Marsh Transmission in Tualatin. (We live in Central Oregon). We had it towed to them and within a short time of looking at our car, they diagnosed the problem. It was a cracked transfer case. Paul sent us a video of the damage. The dealership in Central Oregon has always serviced our AWD vehicle and they were the last to service my transmission. He sent them the video and and worked with the Service Manager to let them know the issue. I wish Marsh could have fixed our issue, however, due to the dealership's insurance rules, it has to be towed back to Central Oregon for repair. Paul did not charge us for the diagnosis and is working with the Central Oregon dealership to have the car towed back here. I now know why our mechanic friend highley recomm

I went to Marsh Transmission for a new clutch and a trans rebuild on my R32 Skyline GT-R. What was originally supposed to be a simple synchro replacement and new clutch turned into a whole new gearset with a few upgrades. The guys at Marsh handled the work with no problems and went above and beyond to make sure it came out absolutely perfect. I can't say enough how impressed I am with their work. Their friendly nature, amazing work, fair pricing and straight forward honesty has made me a customer for life.

Amazing service. Brought my 2018 Chevy Silverado in after it was jerking. A few other shops wanted to replace the whole transmission for 10k. A friend recommended Marsh and I'm really glad they did because it's running like new after working on the valve body. Very quick. You can tell that these folks are not trying to screw anybody over. Great communication. Affordable. Seriously great service. 10 out of 10 would recommend Marsh. Genuinely can not speak high enough about this place!
