Verified CustomerDecember 31, 2013

They do a fabulous job at explaining what needs to be done. They are very honest. They have repaired my car several times and I am very satisfied.

Verified CustomerDecember 28, 2013

They give a good deal. They are professional. They are personable.

Verified CustomerDecember 20, 2013

It's the only place I trust. I've just been going to them for several years and they don't suggest things that I don't need. Their service is quick.

Verified CustomerDecember 19, 2013

I've only gone a couple of times, but every time the owner was very honest about what needed to be fixed. It's just very nice to feel like I'm not shadowed, you know, I'm in the loop. It's nice to know that he lets me know what's going on. I'd definitely say the customer service is great. The service is obviously very well done, and it's just a good way to go.

Verified CustomerDecember 19, 2013

I took my car in and they gave me an estimate. The cost was a little less. They do not try to take advantage of me. I am satisfied with their service.

Good customer service and friendly staff. They did what they said they were going to do.

December 10, 2013

The service is fast and they can accept most credit cards which is convenient for me. They're honest people and I've dealt with him several times. The opening hours are very convenient because they open very early. I can go in very early so it's convenient for me. The cost is reasonable, so when you fix your car it's very reasonable. They also can give a ride if you want to go home or anywhere else. So, you just give them the car and one of them can give you a ride anywhere you want.

Verified CustomerDecember 09, 2013

I think they do good work. I like the fact they offer a discount if you pay cash. They are easy to get a hold of.

Verified CustomerNovember 26, 2013

They have been very polite, very correct in what they're doing, and I have a lot of trust in them. It was an easy location to get to for me and no hassle. This is the third time I've had work done there and each time I grow more confident in my strength of trust in their honesty there. I just felt it was fair. What he quoted me was very close, it was not exact, but it was very close, so I felt good.

I would say highly recommend, but not extremely recommend.

Verified CustomerOctober 29, 2013

I just think they're very knowledgeable and reliable. I think they're honest, I don't think they're going to fix something that doesn't need fixing.

I've had repairs done there multiple times and he always gives me fair prices, and he's quick on his service. He's a small business and I like the small business for my business.

I think that they charge too much, they're too expensive.

Trans Unlimited is AMAZING! Joe Garcia and his staff are exceptional! They for sure have the BEST prices in Portland Metro / Washington County! I have been there MANY times an NEVER been disappointed. Their RATES I cannot find anyone less. These techs truly are knowledgeable patient and caring. Thank GOD for Trans Unlimited! Ever since they saved me over $2000 when everyone else said I had a Transmission problem, and I walked out not even paying anywhere close to that--$500. Incredible! Seriously, if you have an auto/car issue then bring your vehicle to Transmissions Unlimited in Hillsboro Oregon!!! THEY ARE THE BEST!!! Thank you again Joe!
