So I have an 2007 Dodge 2500 with a 5.9 L Cummins. After looking around, I decided to go with the Ats Allison 1000 swap kit. They shipped it out to me. I installed it within a couple of days. It did have some issues to begin with once I got it installed. I contacted Ats and they began to help me troubleshoot the problems immediately we worked diligently for about 2 1/2 months to try and resolve these problems. At this point I talked with my contact at Ats and decided that the best course of action was to bring it to them. So I drove out to Denver. They had the truck for two days and now It works perfect. From what they explained to me, it has been very difficult to source quality parts from OEM manufacturers since Covid which entirely makes sense anybody who’s been involved in the Auto industry is well aware of these problems. From the moment I walked in to their facility, they went absolutely above and beyond to make it an amazing experience. they were nice enough to give me a complete tour of their facility, which was amazing. The tech that worked on my vehicle while I was there communicated to me the entire time. Not only did they fix the couple of issues I was having, but they also took the time to take care of a few other small issues and even hook me up with some upgrades on my truck and some free swag. Highly recommend picking up one of the hoodies, very comfortable. They even checked up on me over the next several days to make sure everything was working perfectly. if you are considering doing an Allison 1000 swap on your third GEN or any vehicle for that matter I highly recommend bring it to them not only will they make sure that it is perfect before it leaves but they will also make sure that you’re taking care of while you were there.

Cody went above and beyond to ensure warranty issue was resolved and handled communication in a very clear manner. Knew I had a 5 hour drive home and exceeded original estimate of time by over 5 hours. Very pleased with the customer service. Would recommend!

Terrible customer service and a terrible experience. First all the first transmissions came without the flex plate. They blamed it on having a new shipper. And the transmission arrived on a palette that was hardly intact and 3/4 missing. I had to source a new one to return the core. I had to have three different transmission to me one after another because the first two were bad right off the gate. In addition they love to use helicoils way too much and their brand new product was contaminated with metal debris. I could literally go on for hours on explaining every last detail and have a mile of paper trail containing emails between us many of which they didn’t respond. Lastly I am supposed to be reimbursed for the last transmission fluid and labor costs for doing it a third time in a row. This has back in December. After several calls and emails I finally reached them and they just said sorry we didn’t see your emails and I must wait another three weeks for my reimbursement. What ever you do go to a different source for your transmission. I am kicking myself that I didn’t spend a tad more and go with a smaller solid company that better cares about their customer service. This has been a major headache that I have been dealing with for literally months almost a year. Attached are just a few pictures of my experience

Absolutely amazing! I have a 2018 Ram 2500 6.7L. Had ATS put on their VFR3000 turbo, pulse Flow Exhaust Manifold and Allison stage three transmission. Roughly two months and 7,000 miles ago. Cody and Makinzie both went above and beyond with service and always responding to emails, texts and calls. Really felt like everything was getting extra attention. Made me feel like my dream truck I ordered straight from Ram was getting taken care of the way I wanted. Went in with a date set for a pickup and on my way down to deliver my truck I started having other problems. ATS was still able to fix all the additional problems and put on the extra parts I ordered within that same time line. When a part was two or so weeks out, Cody thought outside the box and got me a part that same day without compromising anything. I will be back for more stuff even though they're 1400 miles away. They're all great people there loved working with them. P.S. Love the sound and performance of the new turbo. Also the amazing feel of the Allison transmission kit. Really grabs and shifts like it means to grab a gear and go.

Cody was great, got my truck in quickly, communication was on point, and when I could not pick up during business hours he and the shop manager made special arrangements. Also appreciated the full inspection, pointed out a few issue that I’ll need to address, but did not pressure me to have the service done immediately. Thanks Cody and the rest of the ATS team.

ATS saved our family vacation!! We were 1000 miles from home when our truck started having transmission problems. I called Cody at ATS and explained our situation. He was able to get us in and his team diagnosed the issue immediately. We needed a new valve body. What I thought would take over a week, was finished in 3 days! Cody and the rest of the ATS team were absolutely amazing and had us back on the road. I 100% recommend ATS Diesel! They totally went above and beyond to help my family out. Thank you Cody!!

My 18 Ram 5500 was having all sorts of issues and my truck bounced around from mechanic to mechanic with no end in sight. Thankfully I went over to ATS, from the very start Cody was always super communicative and informative of what was going on with my truck. I now have a brand new transmission and a couple other things that were done and I couldn’t be happier with my truck and the service from Cody and the crew at ATS. I will be going to ATS for all future mechanical work!

I have a 2019 Ram 2500 with an ATS Allison transmission. I bought the transmission about 2½ years ago and had it installed by a local shop in Dallas. From day one it felt decent, but being an Allison, I always felt like I wasn’t getting the full experience I expected. I finally reached out to ATS Diesel Performance and spoke with Theo. After explaining what I was feeling, he told me to drive the truck up to Denver so they could look at it themselves. From that point on, my main contact was Cody. Cody’s communication was excellent from start to finish. He kept me updated the entire time and explained everything clearly. Once they inspected the truck, they found several small but important things that had been done incorrectly by the previous shop. Instead of cutting corners, ATS decided to pull the entire transmission and go through it completely. They opened it up, checked every detail, upgraded the clutches, and updated the transmission so it was fully up to date to ATS standards. When I flew back to pick up the truck, I honestly couldn’t believe the difference. It is night and day compared to how it drove before. I now realize how much I was missing out on for the last 2½ years. What impressed me most is that Cody and the entire ATS team did all of this at no cost. That level of integrity, pride in their work, and customer service is rare. ATS stands behind their product 100%, and it shows. If you’re running an ATS Allison or considering one, I can confidently say this is the only place I’d trust with it. Huge thank you to Cody, Theo, and the whole ATS team.

My wife got me the thermal bypass and doomsday device after I talked with Cody about it. Cody took the time to walk me through the install even though both were very simple. I was told the importance of them both and while towing for work. I now have some peace of mind. Every thing helps. I’m extremely grateful for the knowledge that was provided to me.

These guys are awesome! Left my truck with them for two weeks to get a Stage 5 transmission rebuild - couldn’t be happier. Cody kept me informed every step of the way and made sure my truck was ready in the agreed timeline. They also checked out some other stuff for me that I needed done. Cannot speak highly enough of their customer service and the quality of service and parts!

Great company to do business with. I purchased the Allison conversion for my Ram and had them install it. Everything was done in one week! That was over a year ago. Last week I had a noise coming from the transmission, dropped it off and it was fixed within the week, no charge. Cody did a great job of keeping me informed of the progress while it was there. These guys do great work and stand behind the warranty!

Process was simple every step of the way. I had my new transmission shipped and returned the core without any issues. Communication was excellent, and the new transmission works great. I highly recommend ATS Diesel for their professionalism and overall quality of service.

Had to get my 2015 gmc 2500 towed into ATS bc it kept slipping and not shifting into gear . I spoke with Cody on the phone about what was happening and he told me that it was most likely the transmission. Once I got the truck to the shop Cody was very informative of all of the possible things that could be wrong and said that they would get it figured out no matter what. Yes it was the transmission and I’m grateful that it was fixed properly and in a timely manner. Cody maintained contact throughout the whole process, and I personally want to thank him for not treating me like I was a dumb woman that didn’t know what I was talking about. Made me feel comfortable and actually heard. A very refreshing feeling from a very reputable shop. I highly recommend ATS and Cody Thank you

Theo with ATS got me set up with an appointment to replace my transmission in my 2017 Ford powerstroke in a very short manner knowing I had to have it back quickly. He set me up with Cody who definitely has some of the best customer skills I've ever seen. Even after trailering my truck 520 miles and showing up 4 days before my appointment Cody made sure the truck was taken care of and actually had the install complete a day early knowing i had already purchased a plane ticket to go get it. Cody stayed in direct contact with me and if I had a question all I had to do was call and ask him! Great service overall and the product works fantastic!! Thanks Cody and the rest of ATS!!!

I purchased their Allison conversion in 2022. The first transmission lasted about 5000 miles and completely failed. I will say they were good about their warranty and rebuilt it, however I was still out towing and the cost of pulling and reinstalling the transmission. Additionally, it took a couple months to get the replacement transmission back. That transmission has lasted roughly 50,000 miles and is getting ready to come out and go to a local transmission shop to be rebuilt. I simply cannot afford two months without the truck. I went with the Allison conversion because I thought it would be more reliable than the 68RFE. However, I have zero confidence in trying this a third time with ATS On a good note, the install is clean. Their custom Bell housing works well and their translator seems to do a good job talking to the ECM
