I just got off the Phone with the Lady at Transmission Clinic. She was very friendly and professional. I just had a gm rebuilt transmission with warranty through gm. I called them and several other shops to get a quote for a trans cooler or thermostat delete and they were the only honest company that said if any shop other than GM install anything of those, IT WILL VOID THE TRANS WARRANTY! Thank you SO much for your honesty. You have earned my future business!!

This transmission place had been recommended by my mobile mechanic Steve. There was a leak in the rear main seal, which required taking out the transmission. A Transmission Clinic serviced my Honda in A+ manner and also very timely. Kathy kept in touch giving me details of the service and cost as things were uncovered by their team. The car drives like BRAND NEW! I am so happy that I didnt have to purchase another car. I will gladly promote this family-run business, given the great results of their work.

It is hard to find trust worthy people when it comes to mechanics. I brought my Tacoma to A Transmission Clinic with a transmission problem. The Dealer couldnt diagnosed, The shop owner found the problem and fixed it. Save me lots of cash. Very honest people. Your vehicle will be in good hands.

Angel does good work, he takes pride in what he does very happy with the work he did replacing my rear main seal, nice clean work highly recommend.

These guys are awesome! Fernando and his son Angel really know their stuff! I strongly recommend this shop to everyone! I had them replace my transmission in my Chevy Blazer ZR2 4x4, and install a heavy duty transmission cooler! If you are looking for a professional, honest and reasonably priced transmission shop, these guys are the best!

Extremely helpful. I called them for advice and they gave me so much information on how and what to look for when buying a used truck. Will definitely be going to them for future work. Other shops just blew me off because I didnt have the vehicle yet but they were very honest

I paid last year for a transmission job, they gave me 1 year guarantee, guarantee expired on September 2020, February the car star having transmission problems again I took it back to transmission clinic so they can tell me what the problem was or how much will be to repair it, they told me to bring the car at 8:00 am on Saturday I took it on time when I called at 12:00 pm to asked for an update they said they didnt had time to check on my car, very unprofessional place, they dont have word, they only want to charge you for a job and they are not going to fix it properly, dont waste your money in this place take your car somewhere else.

Been waiting on a call for me to take in my car. Has been almost 2 months. No call back or follow up

Awesome!!!!!! Fernando the best. Transmission guy you could go for if your trany went bad..... Good service. And very fast.also for a cheap price... Thanks guys from A transmission clinic......

Came here with a truck that had a transmission that I had no time to fix. Honest people, fair pricing. Even did a complementary OBDii scan on the way out. Over 3 years of abuse later everythings still running strong.

Excellent service.! Highly recommended.

Fernie is the man!! I will not go any where else !! He will look out for you !!

Fair prices, family owned and honest. Ill be back.

Great, no BS service. Fernie knows transmissions!

Thanks for a good deal and a job well done
