Transmission Repair near Ballwin, MO

“I don’t usually write reviews for major mechanical work until I’ve had time to make sure everything holds up, and this shop absolutely deserves one.
Last November, they replaced the transmission in my vehicle. This was no small job—they tracked down the correct transmission for my car, had it shipped all the way from California, removed the old transmission, installed the replacement, and had me back on the road in about three weeks. From start to finish, they kept me informed and made a very stressful situation much easier to deal with.
A few weeks ago, I had another scare when my check engine light came on. Naturally, I brought it right back because they’ve earned my trust. They diagnosed the issue and found that the code was related to an electronic component that had been transferred over from the original transmission—not something they had caused. They explained everything clearly and recommended that my first step should be to have Infiniti update the TCU. They even told me that if the update didn’t solve the problem, they would be happy to work with me afterward to find the next best solution.
What really amazed me was what happened next. Since they knew I would likely have to pay another diagnostic fee at the dealership, they completely waived theirs. They didn’t have to do that, but they did, and that level of honesty and customer care is incredibly rare.
This wasn’t my first great experience with them, either. When I originally needed the transmission replaced, they saved me nearly $2,000 compared to another quote I had received while still doing the job the right way.
The entire team has always treated me like a person instead of just another ticket. They understand how stressful major car repairs can be, and they genuinely care about helping their customers instead of just selling repairs.
Because of how they treated me, I stopped back by the shop with pizza and drinks for the crew. It was the least I could do to thank them for everything they had done. That’s the kind of impression they leave on people.
I can honestly say they’ve earned a customer for life. I’ll continue bringing my vehicles here, and I’ll confidently recommend them to my friends and family. If you’re looking for a shop that’s honest, knowledgeable, fair, and genuinely cares about its customers, I can’t recommend them highly enough.”

“Really amazing experience for a mechanic shop. Anthony was great, friendly, and charged a reasonable amount for the work done, which was fast and has my car running quietly again. It's an old car, so they mentioned a few things that could be addressed but didn't push anything, which I appreciated. Next time I have a more complex issue, I feel confident that they would fix it well and not overcharge!”

“The people and service at Telle are great! I came in for a safety and emissions test and was out the door before I could barely sit down. They provide really good customer service and get you on your way in a timely manner. I’ll definitely be having future services here when/if needed.”

“Always a great experience- very trustworthy! They have gone above and beyond to help with various car situations I have had in the last few years. Highly recommend.”

“We couldn’t figure out what was going on with my wife’s truck! Took it to Tosti’s and they figured it out. Staff is super friendly with great communication. 10/10 recommend”

“Great service!!!!! Great people!!!! While in Eureaka a tire started going flat. Teller Tire got me right in and took care of the problem. Staff is professional, knowledgeable and friendly. Would use them again and will tell others!!!!”

“I recently had an outstanding experience with Custom Auto Center, where my vehicle was expertly repaired. Ken, the owner, and his skilled auto technician provided kind hospitality and meticulous body repair work. This shop’s dedication to providing great customer service is reflected in their reasonable prices. The perfectly matching color and carefully cleaned exterior were added bonuses, as was the quick repair time. I dropped off my car on a Tuesday, and it was fixed and ready by Friday. I will undoubtedly recommend Custom Auto Center to friends and family in need of top-notch auto repairs.”

“We’ve always had a great experience every time we’ve brought our vehicles here. The customer service is professional and the work is trustworthy. Highly recommend”

“Was able to book appointment easily online and received confirmation. Everyone was friendly. Service was completed efficiently. Everything went smoothly. Highly recommend.”

“Economy was able to look at my car the same day and went the extra mile to ensure everything was working correctly. All of this and for a reasonable price. I highly suggest Economy!”

“Very impressed with this repair shop. They diagnosed and completed repairs on my car quickly and efficiently, and at a reasonable price. The employees are professional and courteous. Highly recommend.”

“I've taken one of our vehicles here a couple of times when our usual auto shop hasn't been an option. So far, this has been a great alternative and will use them more often.

I was happy to finally go to an auto shop that provides pictures, video, descriptions, and estimates (via a linked text) for me to review of various recommendations they have after taking care of the primary reasons for my appointment. This makes it much easier to review and sort through which issues I may (or may not) want to fix at that moment. Way more efficient and overwhelming than going to a place and they rattle off 1/2 a dozen things over the phone with a total cost of hundreds of dollars. Leaving the customer wondering what actually needs to be fixed and what is just unnecessary extras, and without any visual references to what is going on under the hood.

Also, friendly and quick service were two extra pluses.”

“My brother told me about this place. I needed work done on my truck so I checked them out. Loved the price. Another shop quoted me more than double the price that I paid here. Mechanic was very nice and explained exactly what he was doing. He did a thorough job. I even tipped him because of his work etiquette. I'll return in a heartbeat. ????”

“Ive taken two of my cars here. Great Prices, very nice and got the work done quickly. They just did a good amount of work on my girlfriend’s car and i haven't had a single issue after. Thank you Roys Auto Repair. Will continue to take my business here.”

“My wife and I have a 2003 GMC Savana full-sized conversion van. The transmission was slipping for a while and less than a week before we were planning to go on a family vacation, there was a clunk and it would not engage reverse. We had it towed to CP and were not surprised to hear the tranny needed to be overhauled. They weren't able to promise that the work could be completed before we left for vacation, but they said they understood our situation and would try their best. Amazingly, they performed a complete rebuild and had our van back to us in plenty of time to test it out on our trip to the lake. The price was competitive and included a warranty that shows they have confidence in their work. Everything performed smoothly on our trip and beyond. We are very happy to have been referred to this shop by Roy's in Manchester. We highly recommend CP Transmission for their great service and high quality work.”

“Berry was fantastic. He quickly and clearly diagnosed my car's oil leak and offered actionable advice. I will be bringing all my cars here in the future. No upsell, no pressure, and very easy in and out. Great experience all around!”

“Had transmission issues with my 2017 GMC Sierra, 67,000 miles, previously diagnosed by another vender. Allen Transmission rebuilt the truck's transmission in just a few days. The truck runs better and quieter than it did after it left the showroom floor in 2017. In addition the service was excellent., from the shop manager, Glenn, to the mechanics, all eager to answer my questions and concern.”

“I rarely leave reviews, but my experience with AAMCO was so exceptional that I felt I needed to share it.

When my Jeep broke down, I was stressed, overwhelmed, and worried about how I was going to get it repaired. To make matters worse, I didn't have towing coverage through my insurance, and getting the vehicle to a shop was going to cost me a fortune before I even knew what was wrong with it.

This is where Josh and the team immediately stood out from every other repair shop I've ever dealt with. They helped arrange a tow for my Jeep and got it to the shop when I wasn't sure what I was going to do. They didn't have to do that, but they did, and it set the tone for the entire experience.

Once my Jeep arrived, Josh kept me updated every step of the way. He explained everything clearly, answered every question I had, and made sure I understood exactly what repairs were needed and why. I never felt pressured or taken advantage of. Instead, I felt like someone was genuinely looking out for me and helping me make the best decision for my vehicle.

What surprised me most was learning that AAMCO does so much more than transmissions. The repairs performed on my Jeep were extensive and included replacing both front CV axles, a rear axle, a rear lateral link, a rear trailing arm, a control arm and ball joint, and then properly adjusting the camber during the alignment to ensure everything drove correctly.

I also want to specifically recognize James for the work he performed. The Jeep drives better than it has in years. The ride is smoother, the handling is tighter, and I can tell the repairs were done correctly. It is obvious he takes pride in his work.

Another thing that impressed me was that they didn't just hand me a repair estimate and leave me to figure it out on my own. Josh took the time to go over financing and payment plan options and worked hard to help me find a way to get my Jeep repaired. That kind of customer service is almost impossible to find anymore.

Throughout the entire process, I felt respected, informed, and valued as a customer. Every promise was kept, every question was answered, and every concern was addressed.

I've dealt with dealerships, independent shops, and national chains over the years, and I can honestly say this was the best automotive repair experience I've ever had. It wasn't just the quality of the repairs—it was the way I was treated from the first phone call until I picked up my vehicle.

If you're looking for a repair shop that genuinely cares about its customers, communicates honestly, performs high-quality work, and goes above and beyond when you're in a difficult situation, I highly recommend AAMCO.

Thank you to Josh, James, and the entire team for helping me through a stressful situation and getting my Jeep back on the road. You have earned a customer for life.”
