"January 2023 I had my truck towed home from this place July 2022 I drove the truck there and put it down payment on to have the transmission rebuilt they could not sync the motor with the transmission when they were done trucks there from September to January with nothing being done I was given excuse after excuse truck was towed home had three shops in the area said they wouldn't work on it because it came from this shop only good experience what was the lady in the front office does her best I would not recommend this shop to anyone and yes he said bring it back after I fix the motor which they put into limp mode brakes did not work when I had the truck towed home Drove the truck there towed it home"

"I dropped off my TH400 transmission out of my long dormant '72 Suburban and asked if they could rebuild it to it's former glory, with importance of keeping everything numbers matching. Every interaction here was so friendly and kind, and they recognized how important this project was to me and made sure everything was done correctly and to my liking. No matter the transmission need moving forward, this is the only place I will trust with my business."

"I highly recommend this business. We had just bought a used car, and two days later we heard a rattling sound. No shop would see us to quickly look at the car. We assumed it was the transmission and found ATEC online. Robin was incredibly professional and helpful and agreed to squeeze us in the next morning. They looked at the car, and while we were fully expecting to need a new transmission, it was just a loose bracket. They fixed this bracket at no cost to us. They are so helpful and honest, and we had a great experience. I would give them more stars if I could."

"Highly recommend this business. Very professional and honest owner. We were traveling from KS to CO and noticed a sound we thought was a transmission problem. We called and requested an appointment to run a diagnostic before we traveled home to KS. We were accommodated without an appointment on a Saturday morning! A great big “Thank you” goes out to Automotive Transmission Engineering Corporation for the professional courtesy we received and the informative explanation from the owner, Donald Ramer, regarding what was causing the sound. We were reassured that we were most likely safe to drive home to KS. When it was time to leave we asked how much we owed them for the diagnostic and they insisted there was no charge. Our experience renewed our belief that there are honest people out there still. I would absolutely recommend this business!"

"I had to have an Odyssey transmission rebuilt. It’s a costly and major repair that my wife and I dreaded. I googled, called 4 shops and stopped by 3 in the greater Denver area and eventually selected Automotive Transmission Engineering Corp. in Northglenn. I believe most other shops do a fine job as well. But ATEC stood out and the impression I got made my decision to choose ATEC over the others a no-brainer. From the beginning to the end of the process of the rebuild my belief that I chose the right shop was reinforced. I’d recommend ATEC for transmission work to anybody who has such a need. More specifics: Pluses: * I started feeling comfortable working with the owner Don immediately after my first call with him. I feel he is honest, upfront about the process and good at communicating and setting my expectation. Meeting him face to face gave me the impression that he’s more an engineer, than a business man. He also gave me a tour of the shop which was very helpful. We even talked about the negative reviews online and I think Don was honest about them as well. There was a hiccup when the work was almost done - a leak in the 1st gear which took a couple more days to fix. Don did a good job communicating the setback clearly and honestly. * The price range Don gave me on the phone was more attractive than the other two shops I checked out. The final price was within the quoted range even after an additional mount was replaced. * ATEC offers a 3-y warranty which is the best among the shops I called. Don and I talked about the details of what’s covered and what’s not. I feel the warranty is fair and good to have. I sense Don is serious about helping his customers through the warranty. I feel strongly that they’ll honor the warranty and in the unlikely event that the transmission fails again within 3 years (even though I hope it would last another 100k miles w/o issues) they will cover all the cost for labor and parts. But more importantly it gives me the confidence that they’ll stand by their work, and they’ll do quality work from the beginning. * Jerry worked on my transmission. He showed me the the laid out parts after it was opened up, and explained to me how the transmission works and what would need to be replaced. Bill helped with the repair as well and showed me a cracked mount to be replaced. Being able to see the damaged parts and the inside of the transmission with my own eyes, and meeting and talking to the guys who actual does the work and hearing from them about the specific was very helpful in building up confidence and trust. I feel both Jerry and Bill are honest and trustworthy people and know what they are doing. * I like the two-week later checkup as a good idea in building up confidence and trust, and proof that ATEC is serious about the warranty as well. Minuses: * The time it took to complete the transmission rebuild was just shy of 2 weeks which was longer than my initial expectation of 1 week although this was due to mostly a storm caused power outage, and a glitch. I wasn’t in a rush and this was understandable. I give them 5 stars. Below picture is my transmission."
