Transmissions Repair and Service Shop In Beaverton, OR

“My Corolla left me stranded on the corner of Allen and Murray. I called a nearby garage and explained the issue I was having and the garage immediately recommended Aatco Transmissions.
Tim and his crew are prompt, thorough -- and (most-importantly) they do the job right the first time! They went above and beyond by driving out to my car, saving me from being towed, and got my car to their shop. They even fixed my driver-side sun visor without me even asking. THANK YOU, TIM!”

“Had my 2016 GMC canyon (diesel) transmission replaced. Price wasn’t the absolute cheapest but it wasn’t far off and way better than the dealership! Plus no surprise fees. It’s been a few months of steady driving and no issues. Happy to recommend”

“This is the first time I’ve written a review, and I was compelled to do so because of the experience I had recently at Tim’s Aatco. The business was highly recommended to me, and I went in for an assessment of my Honda, since I’ve been getting a warning prompt on my panel that there is a transmission system problem. Tim checked it out in about 20 minutes and found that the transmission does indeed need to be overhauled. He went to the added trouble of checking if there was a recall on the problem, since the vehicle has fairly low mileage. He found that there is an extended warranty for the issue and advised me to go to the dealer for the repair. He didn’t charge me for his time, and I found him to be very helpful and straightforward. I appreciated his kindness, candor and no BS approach. If it turns out that the dealer will not or cannot fix the issue, I will not hesitate to take my car to Tim for the repair. Five stars all the way!”

“Tim is always great to work with. We've been bringing our company pickup trucks to him for 30.”

“Did did a great job fitting in my son’s ford ranger for a clutch job. Honest price and work.”

“Tim did not actually work on our 1993 Mitsubishi Diamante wagon, but he sent us straight to somebody who could. It’s an honorable move to send work elsewhere and quality referrals are golden.”

“Tim and his staff were amazing they were able to figure out my problem with the transmission axle for the front end and Tim was informative and didn't try to upsell me unnecessary items. I felt comfortable as a female going there by myself I was informed and educated he even gave me a ride home thank you very much Tim for working with me and thank you for your staff for being courteous and kind.”

“Tim took excellent care of my 1964.5 Mustang. I had tried to replace the transmission pan gasket three times and could not get it right. So I took it to Tims Aatco transmissions, and he explained everything that needed to be done in excellent detail. I parked my car yesterday at 4 o’clock in the afternoon in my garage with a clean drip pan underneath the car. … And this morning there was No leaks whatsoever. I will strongly recommend Tims Aatco transmission to all my friends and family and especially Friend here in Hillsboro that has a 1956 Ford Thunderbird that needs a transmission service. Thanks, Tim!!!”

“Waiting for my 10 day check up. But so far OMG. I work at a dealership and know the ins and outs as a tech. Tim was amazing. From explaining it like I knew nothing( doesn't know my background) and treating me with respect and most importantly, HONESTY. His estimate was right what he quoted me since no further gear damage was found. My car runs flawlessy and like brand new for having almost 200k ! Thank you Tim. I was scared to get my trans work done since I didn't have the knowledge, you made this very easy on me!”

“I came in with a CEL for a transmission issue for my ‘01 4Runner just hitting 190K miles a few months ago. Tim & crew ran some diagnostics and determined the bad news. Didn’t try to sugarcoat the issue and was upfront that it needs a full transmission rebuild, quoted me a reasonable price (I priced around) and I got it done in a timely manner. Highly recommend his shop for all your transmission work! Even after a few months he still helps me out whenever I have other non transmission related issues and also recommends other shops if he can’t provide a solution for that issue and his shop crew is top-notch!”
