Gary's Transmission Service

I can’t recommend Garry’s Transmission in Katy, Texas highly enough! I had my transmission rebuilt right before Christmas week in 2024, and he made it happen in time for the holidays — which meant so much to me. Now it’s January 2026, and my transmission is still running good and strong with zero issues. That kind of reliability speaks for itself. You can tell Garry takes pride in his work and does the job right the first time.

I'm super impressed -- Gary took time out of his day to talk me through my options, even though he knew he wouldn't be working on my vehicle because my situation requires the dealer to get involved. I wish I could have him do it instead! He gave me referrals and recommendations. Gary is incredibly knowledgeable and strikes me as a man of integrity. I hope he continues to be wildly successful as the owner of an independent shop.

I called Gary’s Transmission Service about an issue with my car, and even though he didn’t look at it in person, he took the time to explain what was really going on. He was upfront and told me that even a temporary fix wouldn’t solve the problem long-term — which shows real integrity. It’s rare to find a mechanic who’s this honest without trying to make a quick sale. I respect that he was straightforward and didn’t try to give me false hope. I’ll definitely keep Gary in mind for any future work — someone who values honesty like this deserves credit.

Gary's transmission shop is hands down one of the best in Katy. I took my car in 2016 Toyota Camry SE and they took care of my transmission fluid change. Easy to book, great price and a professional team. Gary and his team are very knowledgeable and true professionals. Highly recommend. Thank you kindly Gary

Jun 3024 - OUTSTANDING! I highly recommend this business. Gary and his technicians KNOW transmissions. I dropped off a 2017 Surburban with 137k miles throwing off 4 engine/transmission codes and running BAD! Gary was up front and shot me straight on the necessary repairs, cost, and time it would take to fix. He said 5-7 days doing it in 3 because he had parts in stock and was highly experienced in this vehicles repair needs because they see these vehicles frequently. The tru k is running like a top 👌. The newly rebuilt transmission shifts smooth, does easy take offs, and stops with no issues. It's feels like it's a new truck. These guys KNOW their craft. I highly recommend their services if you're within 40 miles of Katy for all your transmission needs. Thanks, Gary, for doing it right!
