Will use them again without hesitation

They could have said that the whole transmission needed to be replaced. I would have never known the difference. Instead, they did a free diagnostic and found that it was only a sensor, which they replaced and then serviced the transmission. We came out owing much less than we thought. In talking to another 'car guy' about our experience there, he said that what we received was right on the mark and for a great price.

I have heard horror stories of transmission places and so I was apprehensive to go (not that I had a choice). But luckily I was referred here. I will be coming back any time I have a problem without hesitation.

A guy you can trust!

I have been taking my autos to Tim's for over 10 years. Being a single mom taking my only auto to be checked out was somewhat nerve racking but Tim and his crew made it easy. I thought my tranny was not shifting correctly. He put it up on the lift and checked it out at no cost! Luckily my tranny was in good shape! He could have told me it needed work and I would have believed him.

Since then I have taken him all my cars, my kids cars, and my boyfriend took his truck in when it was stuck in 4 wheel drive they fixed it for nothing!

When my oil changing company tells me I need tranny work I say ""Thanks for the info!"" and head over to Tim's to get the real scoop. If he tells me I need a flush then I have it done by him.

Thanks Tim!

transmission professionals!

Tim and his staff did an outstanding job with my transmission work! I could not be more pleased with the service that I received. They even made a quick adjustment not related to the tranny work. Thanks Tim!

Best bet for your auto and your wallet

I had previously been to this shop for transmission service and was happy with the work they did and the prices charged. I felt they did a good job and did not sell me services I didn't need or overcharge me.
I found myself again with problems and guessed it was transmission. I called the shop and told them the trouble I was experiencing and Tim agreed the transmission was not acting right and recommended that I have AAA tow the car rather than drive it in.
My car was puzzling to diagnose but they stayed with it and eventually replaced the computer. I was very grateful for the time and effort they put in. My car is running great now.
I have many times paid for repairs that didn't cure my problems. Guesswork can be costly when it comes to auto repairs.
I have complete confidence in this shop. I only wish more auto repair places were this honest.

Fantastic service

I've had 2 transmissions rebuilt at Tim's and have been having my other transmissions serviced by him for 5 years. I'm overjoyed with his service. He's charged what he said he would and the jobs were done when he said they would be. When I'm having a problem his technicians will take the time to figure out what's wrong and won't just recommend replacing the tranny. I've recommended this shop to several friends and they've been pleased with the work as well. Thanks.

Best transmision shop in Beaverton area

I own the general repair shop, but when I have transmission problem I always call Aatco Transmission, because they are honest and stand behind their work. They have very experience crew working overthere, Dan ( the shop foreman ) is very good at what he does, he spend time to test drive with customer and explain the what wrong with it. The owner Tim very nice man, I have problem eventhough not their fault, their still take care of me, without question ask. Highly recommend to anyone in the Portland Metro Area

Tim's AATCO has provided me honest and affordable transmission and clutch servicing for over 15 year

You won't find a better transmission and clutch shop around! Some may be cheaper, but are not as honest. Tim will give you ""straight-forward"" evaluation of your transmission and/or clutch condition, then do quality repair and/or servicing to keep your vehicle on the move. He also stands behind his work and will fit you into a busy shop schedule if you have servicing that is untimely, such as an emergency or late repair prior to a vacation. Preventative maintenance is the key though, so every vehicle owner needs to follow their owners ""maintenance manual"" servicing schedules to avoid costly repairs. You know... the one in your glove box with all the dust on it! And No, other than transmission or clutch servicing, I'm not his buddy. But he is a personable character and he knows his stuff... which I highly respect and that is why I took the time to provide this review VOLUNTARILY.

So give him a call... you'll be glad you did. Hopefully you will be his customer longer than the 15 years I've been. Happy motoring- Rob

I went into Tim's Aatco in Beaverton on Wed. for a transmission repair. Being a woman I was quite nervous but the men there were very kind and very knowledgeable. My car was done on time, it was slightly cheaper than they quoted me too. I would highly recommend this shop, even though they were busy, they were very friendly and timely.
