Serving Washington County since 1979, our family-owned and operated transmission shops service and repair all makes and models of cars, trucks, and RV's. We focus in automatic and standard transmissions, clutches, 4X4, rear ends, drivelines, axles, and transfer cases. Your vehicle's check engine light can come on for many different reasons. Reliable Transmission offers a FREE multi-check and scan where we can help identify your vehicle's problems.

This FREE service includes, a test drive where a technician checks the shift points, and a visual examination that includes: checking fluid levels, an examination of the modulator and U/CV joints, and also checking the vehicle for leaks.
Services
A transmission service is different than a "flush", which only changes the fluid and often clogs the filter with the impurities from the old oil. Our transmission service consists of a road test, removing the transmission pan, a visual inspection, draining the fluid, changing the filter and pan gasket, and adjusting the bands and linkage.

So after reading all the wonderful Google reviews I decided to take my car into reliable transmission and I had to do it over the weekend because I used my car for client transportation with work. I dropped it off on a Friday and had to come pick it up by Sunday and it still wasn't even looked at. I called on Saturday and The guy I talked to stated he put it on the machine and by the time he was done doing something else the transmission was too warm to test it again.

I then called on Sunday to see if it was done and ready yet and he said he had a car come in that should have taken 20 minutes that he went to go look at and it ended up taking several hours with the other car so he never got back to my car :- my transmission is still not fixed and I still have no clear answers as to what's wrong.

My car started slipping really bad and I assumed my transition needed replaced. I was referred to Reliable Transmission and they found my transmission was leaking fluid and just needed a small repair. I was so lucky and grateful that they were honest and didn't take me for hundreds (if not, $1,000) of dollars.

Took my 1998 f150 in for shudder at 35mph. Turns out wasn't a transmission issue but a miss fire took it next door for me and had the work done. Great service

Absolutely recommend this shop. The owner, Jason, is great to deal with. Thought the transmission on my Tahoe was going out. One dealer did not have a transmission tech. The second one I called couldn't take me for 3 weeks. Took a chance on Reliable after reading the reviews & glad I did. Called, & Jason said bring it in right then. An hour later, he called & said all I needed was a fuse, which he replaced for free.

He advised I get the fluid changed. Vehicle was ready the next day. They gave me AAA discount on the service. All in all it was a great experience. Will never use another transmission shop.

I'm blown away by the integrity of Reliable Transmission. In a world of dishonest business, they told me my transmission didn't even need service and explained a couple possible mechanical issues for me to pursue. I'm very grateful for Reliable and Jason for the help! You can trust these folks!

Reliable transmission performed a transmission flush for less than the dealer. Very knowledgeable in what they do, and were quick to answer any questions I had. Would definitely recommend to anyone in the area who wants quality work done on their vehicle. Service: Transmission

My 1998 4Runner started developing a "floor" vibration over a year ago that you could feel when you got up to about 60mph. I took it to the dealer a couple of times and they re-balanced the tires but it didn't fix the problem. I dealt with it through 2020 since we didn't drive much but starting early this year I started driving and after a few months, the vibration started lower and lower in the speedometer in that in the last month, I started feeling it at 40mph.

I took it to Les Schwab last month and they re-balanced the wheels again, but again to no avail. However, before I left Les Schwab, the manager said that if I'm feeling the vibration more on the floor and there's no steering wheel shake, then it's most likely something to do with the transmission area. So I looked around and found Jason at Reliable in the Hillsboro branch.

I was anxious because all I know about transmission repair is that it is expensive. I dropped off the truck in the morning and in the afternoon, I got an update that the rear yoke on the transfer case was loose and they tightened it up. Jason wanted to keep the truck another day to see if there's something else going on like a warped rotor rubbing against the brake pads.

The next day, late afternoon, I got a call from Jason who let me know that they've eliminated the vibration! I went over there and he re-explained what they found and they also did say that I should get the rotors checked anyway later on but the vibration should be mostly gone. I asked Jason what I owned for his miracle cure and he said "Nothing. It took me 5 minutes to tighten the bolt and the test drive is free so it wouldn't feel right charging you." -- what?

Who gives free service these days? So after talking shop for a few more minutes and getting to know the other businesses around there and getting other recommendations for vehicle repairs, I left and drove my truck to the freeway. O M G. She drove smooth as butter! Now I can take the truck on longer drives without it rattling my teeth off. THANK YOU JASON and Reliable Transmission. You guys are a rare gem in the auto repair business.

Nice to have an honest mechanic to diagnose and perform what needs to be fixed at a fair price. Could have easily claimed more to fix and charged way more ans I never would have known. Honesty and integrity is rare in this vertical and nice to see. I will gladly do business with them again as they would be my first call. Service: Transmission
