Transmission Repair in Tualatin, OR

“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 recommend Marsh Tranmission to us. He has used them for years and feels they are the best in the valley.
Paul went above and beyond our expectaions in the entire process. We will use them in the future and will definitely recommend them”

“I recently traveled from South Texas to Oregon to assist my son with his relocation back to Texas. During my visit, I encountered a check engine light on my Mercedes. Being far from home and needing to drive back, I was eager to find a reliable service center. I discovered Star Motors in Tualatin, Oregon, where Nathan and Jonathan provided prompt and exceptional service. They ensured my vehicle was safe for the journey ahead. I highly recommend Star Motors to anyone in need of automotive service; they are genuinely honest and professional.”

“Mike was absolutely a pleasure and legend to be able to talk to and work with. After being screwed over by unknown costs by other shops and screwy people running stores, Mike was honest, kind, and extremely straight forward with all of the work and they were going to do for with my car. As well as this I am a student and working a minimum wage job so getting a large sum of money is hard to come by, which Mike again was understanding and patient of my situation. Nonetheless great people, great work, these guys absolutely deserve all these five stars and compliments.”

“Update: November 2025! I'm still going to Sherwood Auto Repair and if I can help it I will never take my vehicles anywhere else. Not only are they amazing at communicating on my level, Katie and Alden helped me understand that my partner's car needed a muffler mount replaced and that it made more sense to have it go to a specialty shop because it would be more cost effective! I am so impressed that I will continue to drive from Gresham to make sure that my cars are serviced right. Fours cars over the years and no one but Sherwood Auto Repair will be touching them unless they tell me to go to a specialty shop!

I've been bringing my cars to Sherwood Auto Repair for the last four years. I love their model. The very first day I brought the family mini-van in they asked me what my goals were for my vehicle. We were paying off debt and getting everything in order, and I told Scott, I want to run it until the wheels fall off. They treated that vehicle like it was a priceless sports car. The wheels have fallen off, and I bought a new van. I will be taking it to Sherwood Auto, and if I have anything to say about it, my kids will be customers. I can't describe the value and peace of mind I get knowing that my family is safe and that the folks at Sherwood Auto don't cut corners. Thanks so much from the Rulmyr family!”

“They made a custom driveline to replace the destroyed one. They knew exactly what they were talking about and I couldn’t be happier with this new driveline!It fit perfectly too. I will them with anything I need in the future. Keep up the great work guys!”
