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.

“ATS is truly dedicated to their customers having excellent experiences with their products. I had an issue a few years in with the Allison conversion in my 2019 Megacab and they replaced everything with no questions asked. Truck is back to running excellent again. The Allison conversion is more than just a beefier/higher quality transmission, the custom TCM tuning (raised shift point RPM's) was more of a seat-in-the-pants improvement than another other mod I've done. The 5-Star billet converter also allows me to back my 30' boat up my lengthy garage approach incline with minimal effort. Transmission runs considerably cooler than the 68RFE as well. Thanks ATS Team!”

“Fit and finish were perfect; obviously larger flow area compared to factory manifold. Clear instructions. Bolted right up with no clashes and exhaust blanket for factory manifold fit just fine. Turbo spools quicker. Drive pressure and EGT's are both down from before with same load on same roads. Return customer because customer service and support and product materials and workmanship has always been outstanding for me at ATS.”
