I highly recommend Gary's Transmission to anyone looking for an honest assessment and quality transmission work. I brought my truck in expecting I'd need a rebuild--or even a full replacement. Instead, Gary took the time to properly diagnose the issue and told me it only needed a transmission fluid service. The difference was immediate: it now drives like new. Gary is extremely knowledgeable, straightforward, and the work was completed quickly. I'll definitely be returning every 50,000 miles to have the transmission serviced on both my cars and trucks. Thanks again for the excellent service! read more

Had Gary rebuild a transmission on a 2019 Chevy Silverado. The work was done within the time frame given and the truck appears to be working fine now. The price ended up being exactly what was quoted and the receptionist was great with customer service. I would recommend Gary to my friends. read more

Gary took the time to answer all my questions concerning the transmission rebuild. The shop was easy to find and customer service is excellent. Overall great experience and highly recommended Gary's Transmission Service for transmission work. Vehicle runs great now and no issues with shifting, but it may take time to have the repair completed since they are always booked up but well worth the wait. Sometimes if you want want it dome correctly you have to wait awhile little bit longer and I give them 5 stars. read more

Gary and his team went above and beyond in the service they provided to me. I had my transmission rebuilt with them previously and it drove great for the entire term of the warranty... after a bad battery caused problems which unfortunately affected my transmission, Gary worked with me and ate the labor costs despite my truck being outside the warranty terms he provided me on the previous rebuild. Not only that, but the total cost was less than the ballpark he quoted me. Shoutout to Cl and St for dealing with my persistence with grace. I will be recommending you to friends and family read more

Got my baby back! #Syngap1mobile New Transmission and PAID OFF TABOOT! $2,000 less than Ford and a brand new one, not rebuilt! Great people! Honest and recommend quality work! read more

Gary's Transmission Service, Inc. - Auto Repair Near Me - Katy, Texas

I took my 2005 ram 3500 dually truck to have the transmission (rebuilt not replaced with a less desired one) and I got it back in terrible condition. Gary drives the identical truck to mine and I believe they kept my good transmission to be used in their truck I in order to achieve better fuel mileage and shifting advantages. The transmission I now have causes me to get terrible fuel mileage, it downshifts hard, and it chatters when I back up in reverse with any size load. My truck also has much less pulling power and I need the pulling power to pull tree debris in my trailer back-and-forth to Houston. I had to spend about $4000 or more to repair my engine because I found in the end that I now have old aftermarket sensors on the fuel rail that caused my truck to rev up uncontrollably. I replaced all of my fuel injectors, trying to figure out why the truck was overloaded with fuel, but it was because someone replaced my factory parts with old parts. I wonder who did that and I wonder who replaced my ashtray with a broken one that has been used for smoking in the past . I really don't like my truck anymore and I used to love my truck. I already know that they will deny it and ask me to bring my truck in to be examined. There is no way I would bring it back even when it was under warranty I wouldn't bring it back when I realized what they did. It's very depressing and hard for us to recover and keep our business going at this point. read more

Gary's Transmission Service, Inc. - 2005 RAM 3500 4WD parts swap? - Auto Repair Near Me - Katy, Texas

I have used Gary for several of my vehicles. I drive a lot and run my vehicles to 200K+ miles. He has rebuilt a couple transmissions for me and when I thought my latest vehicle was having transmission problems, he correctly diagnosed it and toils me what I needed. I have found, it's rare to find honest people in the automotive repair industry. Gary has always been honest and has provided great service. I highly recommend him and his business.

Took my son's truck in for a new transmission, lasted 6 months. Gary fixed it free of charge but this time it only lasted one month. Again, Gary admitted they had made a mistake but advised that we should check the transmission fluid every time we get gas. This time the transmission lasted a year. Problem was that my boy was at school in Arkansas. Gary, being a good sort, did say that if I could get him the truck, he would take care of us. Not practical, so we took it to a transmission shop in Arkansas. There it was replaced and we never had any transmission problems again. My son drove it for 10 more years and when we sold it, the transmission was still good. Maybe just bad luck, but even though Gary seemed honest and likeable, I cannot recommend this place. read more

Older well maintained 5.4L F150 indicated subtle trans slippage during freeway speed variations, especially on inclines. Fluid replacement was considered the best option. However, the subtle symptoms became more pronounced under the same driving conditions. Upon return, Gary determined the engine was misfiring due to multiple coil failures. In a perfect world, the problem would have been identified the first time but I was satisfied with the end result. I will continue to use and recommend Gary's Transmission Service to family and friends. read more

Trustworthy, economical and fast. I can't believe I finally found a reliable mechanic! I was quoted $1,200 by a large company in Katy, but Gary's did it for $420. He is a specialist and knew exactly what was needed. A real Godsend! read more

I searched for a trusted transmission shop in Houston. Gary's is the only one that showed up on the west side, near Katy. I brought in my 2011 Ford Explorer with 206K miles having transmission issues. Gary diagnosed the issue and determined changing the transmission fluid was all that was needed. Any other shop would have told me I needed a new transmission. Gary's deserves the high rating on Yelp and they will always have my trust. I highly recommend anyone on the west side of Houston to see Gary for transmission repairs and service. read more

Honest and prof professional! I have a 2011 Lexus SUV with "lifetime transmission fluid" that started having engine codes for the transmission solenoids sticking. Dealership wouldn't even diagnose or service, only change out for a new trans for $8000. Gary diagnosed the issue quickly, performed a simple service and got me back on the road for a great price. read more

Gary gave our son first-class and honest service when he was stranded with a bad transmission problem while on a drive from California to Florida. Our son limped into Katy Texas, found Gary's, and Gary took care of his F-150 truck's transmission problem in record time. Most other shops would have taken advantage of the situation and overcharged for the service but Gary did not. His price was lower than expected and our son is back on the road with his transmission working great again. Thank you so much Gary!! Jerry & Nancy Bransford read more

Outstanding service at reasonable prices. Family business with years of experience. I definitely recommend Gary's Transmission Service.

Our 2012 Kia with manual transmission stopped changing gears one day. Ugh. Transmission issues, not fun. I called a few places and explained the issue and wasn't getting a good feeling about taking my car there to get fixed. I found Gary's Transmission online and talked to Gary about the issue. Right away he knew what it was and what was required to fix it. Very knowledgeable and really fast service. Definitely recommend for your transmission repairs. read more

2 other mechanics could not figure out why my transfer case was leaking fluid through the output shaft. Gary's not only figured it out but had it fixed the same day at a fair price. Need an honest transmission shop this is the place. It's a clean shop and not fancy so they don't charge you fancy prices. read more

NO COMMUNICATION!! The transmission in my car stopped working properly on a Thursday. It took until the next Tuesday (12 days later) to get my car back. I could've, and would have, forgiven the time taken. However, received ONE phone call that whole time (which happened early on...maybe that first Friday just to give us a price). We had to make every single other call to get updates. Then, we called again yesterday and were finally told the work was done and the car would be ready the next morning. When we got there, we found out (1) they do not accept personal checks and (2) there is a 3.99% charge for credit card payments. WTH?! This would've been great to know before we got there. The clerk/receptionist claimed Gary documented telling us, but he didn't. Instead, we were stuck paying it because my husband took me on his way to work. We are blessed to have to money, but we had to split it between cards. We will NOT go back to Gary's. read more

I had an axle seal go out in my car and it wasn't shifting right. The mechanic we have been going to for years does not do transmission work. He told me to take it to Gary's. Turns out the bushing was bad. Gary fixed the problem at a very reasonable price and my car is running great. If you need transmission work this is an honest shop that will take good care of you. read more

Excellent customer service, very knowledgeable, and best price in town. Would highly recommend to anyone needing transmission repairs.

Gary's shop was recommended to me by a friend who's big into the offroad 4x4 scene. You figure if a shop can make tough transmission for those rigs, they can make a lightly modified one for a street car, and you'd be right! Gary is a pleasant, well spoken guy that's enjoyable to talk to. His shop is pretty clean considering the mess that comes with working on a gearbox. I was pleasantly surprised to get my transmission wrapped up in a thick plastic bag so it won't have a chance of messing up my cargo area. And the end result is that I got a transmission that shifts better than what the factory gave me! The price was spot on, probably very similar to the major chain stores. But what really matters is that Gary's shop didn't treat me like a pinata, they told me what it would cost, made a great transmission, added a part that I wanted later on (a different pan) and the price didn't change. There were no surprises! read more

My mechanic recommended Gary and now I know why! Took my 20 year old pickup in as I thought the torque converter was going out. It was acting similar to when it went out about 10 years ago, so I thought i might be catching it early. Gary ran some tests and told me he didn't think anything was wrong and my concern may just be miss-fire (coils are definitely overdue). This is honesty. He didn't make a lot of money off of me, but he earned my trust. Thanks Gary. read more

I had also previously complained about the fact they don't accept cards without a fee. I even left a bad review about it. But as a business owner, I get it. I recently had a client stiff me so I also had to modify by payment acceptance policy. However, I think Garys should have it stated on the paperwork the customer signs when dropping off the vehicle. Other than the payment issue, the transmission has worked flawlessly since the rebuild. Also, we and a linkage issue due to the age of our truck and Gary walked my employee through the repair so the employee would not be stuck at the side of the road. We put around 50K miles on the truck annually and the rebuild transmission works like new. read more

He did a great job on my 1987 Corvette transmission... it has been over 18 months since the repair ... he also fixed a broken mounting bracket.... that was causing a thud ... I brought it in to him at 1 year all was ok... no leaks no problems .... the repair price was very reasonable .... Use this guy ... He cares and will do the right job ... Thanks !!! read more

So I recently received horrible news from the dealership. "You need a new transmission", right away all I could think about is the price tag. They also told me that I shouldn't do a fluid change because it will ruin my transmission and that they found fragments of my transmission in the fluid. They were charging me 6k+. So I began shopping around for rebuilt transmissions, because there was no way I was going to get it directly from the dealer. I came to yelp looking for transmission shops and found Gary's Transmission. I got in touch with them and dropped off my car. They ran their test on my transmission and said that everything was ok. They found no fragments in my fluid and told me that my pan wasn't even removed by the dealer. All I needed was a fluid change and to fix a leak. I serviced the transmission for a couple hundred bucks and my car has been running amazingly. The dealership told me that changing the fluid will for sure mess my transmission up. All I can tell you all, is that I dodged a bullet. I am servicing all my cars with Gary and his crew from now on. read more

Gary gave me an honest opinion of my situation without charging me hundreds of dollars. Just $85 for the evaluation of my transmission and a straight forward result! Thank you Gary! read more

I didn't know what was wrong with my car. I just knew there was an issue with the transmission. I found Gary's Transmission on Google Maps. It was close to home and had only 5 star reviews so I decided to give it a try. I spoke to Gary on the phone. He explained there would be a $65 evaluation fee and no work would be done until he spoke to me first. The good news came when Gary told me my transmission was working perfectly and the the issue was something else. He even referred me to a local shop to do the repairs. Any other shop would have tried to rip me off but Gary didn't. It's hard to find people you can trust these days. I will definitely refer anyone to Gary's Transmission. read more

Your one stop shop for all your transmission needs. A complete stranger to Gary's Transmission and he went way beyond his duty to help my husband and I out of a bad situation. This is A #1 stand up guy. Big Thank you Gary and staff. Thanks for making us feel like a family member, he's a RAM 5500 EXPERT ... The Fangue- Davy... read more

I've been going here for years. Longer than I can remember actually. They do the best work, and they are honest, and friendly. Not much else to say. They have all of the qualities that matter. read more

Breaking down over a 1000 miles from home always leaves you vulnerable to those that would prey on your misfortune. That is when you pray for a fair and honest repair shop. I was on a 2+ week vacation around the country with my wife and kids when we broke down near Katy, Texas. Gary was that answer to prayer. He moved us to the front of the line and gave us an honest assessment (at a better than fair price), even though he knew it meant his shop would not get the needed repair job. Additionally, he went beyond the call of duty in providing guidance and some local information that allowed us to continue our trip back towards Virginia on that same day. He was a bright spot in what was otherwise a very difficult situation! It's not often that you leave a mechanic's shop thankful that you were there. Thanks Gary! It is my pleasure to highly recommend your shop! read more

Needed U joints replaced on my 2000 4Runner. Started the job myself and after getting the drive shaft off the vehicle and removing the first joint I decided, this would be much easier for a trans shop to do with the right tools. Called up Gary's and low and behold Gary picks up the phone. Quickly explained the situation and what needed to be done. Gary fit me in that day and got the work done quickly. Brought in the parts and Gary pressed out the last blown U joint and pressed in the two new parts. Great price, great work, great experience. My 4Runner has 171k on the clock and as a DIY kind of guy I really appreciate finding a shop that can lend a helping hand when I'm short on time, tools, or just plain in over my head. Gary just became my go to transmission shop! read more

It is always nice to speak with the owner of a repair shop. Gary and his team performed a transmission refab for our Jeep that was reasonable. The service was great. When we had a follow up issue, they were able to repair it at no charge and very quickly. We will go back if we need too. read more

You hear about people being ripped off by auto repair shops and dealers all the time. It's hard to find a reputable shop specially a transmission shop. I was given Gary's transmission shop information in Katy, Tx to take my car over there with a transmission issue I was having. Gary is a straight up reliable person and WILL NOT BS you about what will it take to fix it or the issues he finds wrong with your car or truck. I was so please not only by the service but he does go out of his way too make sure a customer is taken care of. The Mechanic who did the job forgot to mention he broke the negative post on my battery. I called Gary and he said just bring over and I'll fix it. He fixed it during his lunch. No charge and made sure I was happy b4 I left... Do I need to say more??? I will not hesitate at anytime I've got a transmission issue or service due on my car and have them do the work... read more

Still can't get over the wonderful service and fantastic support I received from Gary and his techs. Was expecting the worst and was filled with gratitude that the honest and quick service saved me soooo much. Instead of just taking advantage, he did an honest diagnosis and replaced a cable, instead of selling me a new transmission. No words to express how happy and relieved I am to have found an honest auto repair person. (Though this wordy review might say otherwise on the "no words" part). lol Can't see me recommending any place else. And will be the first I call, no matter what happens with my car, as I would trust who he recommends. :) Thank you Gary, for taking care of this for me. Proof to me that prayer is answered. read more

Excellent service , Gary is Honest and fair with his prices. I tried his company a couple of years ago for one of my fleet vehicles and he figured out that we did not need to replace the transmission . We have used his company since for all our transmission issues on our entire Fleet . Would strongly recommend this company . read more

Gary and his guys know their stuff. I took in my truck, and it turns out it just needed to be topped off with fluid! He wouldn't even charge me for the fluid he put in! They are honest and friendly. read more

Gary's transmission was thorough and helpful in the assessment of what was wrong with my vehicle. They didn't work on it until I knew exactly what was wrong, how much it would cost and how long it would take. Gary was also helpful in his advice moving forward and never tried to "hard-sell" me. I would recommend Gary's to anyone who appreciates honest, informed work. read more
