From full-time RV users who travel nonstop, to high horsepower competition based vehicles, ATS has the answers.


Clint Cannon and Ranee Elder founded Automotive Transmission Specialists in 1993. At that time, the company specialized in transmission repair for all types of vehicles. In 1997 the company "Performance Torque Converters" was founded and they started doing torque converter rebuilds in house. Bringing the capability of building torque converters in house gave them more flexibility to service their racing customers. As the popularity of diesel trucks grew and more people became aware of the power upgrades available for their diesels, problems with diesel transmissions emerged.

Clint started research and development into a more robust torque converter to address the transmission issues. It was discovered that a clutch pack design was the answer to providing a robust torque converter. The development of the TripleLokĀ® Torque Converter and a company focus on Diesel Performance products resulted in a rename of the company to ATS Diesel Performance.
