ATS Diesel Transmission

About ATS Diesel Performance

Few names carry as much weight in the diesel performance world as ATS Diesel Performance. Founded by Clint Cannon in 1993 as a general automotive transmission repair facility, ATS has grown into one of the most respected manufacturers of diesel truck performance products in the country. From its roots in transmission work, the company evolved into a full-scale engineering and manufacturing operation, building a reputation that diesel truck owners from coast to coast rely on.

Headquartered in Arvada, Colorado, at the base of the Rocky Mountains, ATS benefits from a uniquely demanding testing environment. Year-round temperatures that swing from well below zero to over 100°F, combined with elevations that can exceed 12,000 feet within a short drive of the facility, give ATS engineers real-world conditions that stress-test their products far beyond what many competitors can replicate. Everything is designed, engineered, and manufactured in-house — a commitment that ensures consistent quality and allows rapid iteration on new product designs.

ATS Diesel Performance has remained a family-owned and operated business throughout its history. The brand is best known for innovations like the patented TripleLok® Triple Disk Torque Converter — long regarded as an industry benchmark — as well as billet transmission builds and the TRANSlator™ CAN-Bridge integration system. Their product catalog covers a wide range of drivetrain and performance categories for Cummins, Duramax, and Powerstroke-powered trucks, including Allison conversion packages, turbochargers, fuel system components, electronics, and exhaust manifolds.

On the drivetrain protection side, ATS manufactures differential covers cast entirely in-house from aluminum, featuring external cooling fins and expanded fluid capacity for superior thermal management. For those upgrading or rebuilding their automatic transmissions, ATS offers both automatic transmission flexplates machined from billet material and purpose-built automatic transmission oil coolers designed to keep fluid temperatures in check under heavy towing and performance demands.

Whether you push your diesel truck through mountain grades hauling a fifth wheel, run it at the track, or simply demand more reliability out of a daily workhorse, ATS Diesel Performance has built its entire product line around the idea that diesel trucks deserve better than factory spec. With over three decades of engineering expertise, in-house manufacturing, and extreme-environment testing, ATS continues to set the bar for what a diesel performance part should be.
