About ATS Diesel Performance:

From our humble beginnings as a general automotive transmission repair facility in 1993 to our industry-disrupting product releases in 2021, ATS Diesel Performance has remained a family owned and operated business. ATS Diesel Performance designs, engineers, manufactures and installs upgraded transmission components, exhaust manifolds, electronics and turbochargers for Cummins, Duramax and Powerstroke powered pickup trucks.

Founded by Clint Cannon in 1993, ATS Diesel Performance has earned a reputation for industry leading design and manufacturing processes. Beginning with our groundbreaking Triple Disk Torque Converter design, the TripleLok® Torque Converter, which quickly became the industry benchmark, to our cutting edge TRANSlator™ CAN-Bridge integration system, ATS Diesel Performance has been a constant innovator in an industry that is fueled by competition.

ATS Diesel Performance is located in Arvada, Colorado, at the base of the Rocky Mountains. Our location allows us to test our products under extreme conditions; year round temperatures range from -10° to over 100° and elevations can exceed 12,000 feet above sea level within a short drive of our facility. This combination of factors ensures that we are able to measure performance and functionality in the wide range of conditions that our customers will encounter in real world use.

“I have installed 2 of the units on friends trucks. In both cases the transmission temperature dropped 20 degrees. So I just bought 2 more for my 2 trucks. Easy to install/ follow the instructions. The work great. A very inexpensive transmission life extension”

“Quality of the covers appears to be excellent. Fit was good and I don’t have any complaints. A spec sheet with torque specs would have been nice but I was able to download from the ATS site. I guess I am too old school to think this way. Also, if you have put on larger diameter tires I am pretty sure clearance will be an issue.”

“Great customer service! I called at closing, no answer. Shortly I received a call from Fabian that they missed my call. He helped me with a discount for Black Friday which was a bonus. If you need the item soon to get your truck back on the road , just pay the extra shipping charge. UPS took several days longer.”

“I had to call about shipping. My pan was shown on tracking to be stuck at ATS. When checked into it was sitting on a bench. Paperwork was finished but pan was over looked for shipping. I called twice and they did get it shipped😀. It took longer than I thought (2 weeks) but worth the wait. Don't let my story stop you from ordering. This pan is worth waiting for. You can probably fine a cheaper pan but I bet you won't get the quality. Thanks ATS and sorry I don't remember the ladies name that helped me. I spoke with her twice so she must work in customer service and she's was very nice to me and got the pan shipped. Thank you.”
