It’s built to meet the needs of serious truck owners who push their rigs every day, whether for work, play, or a little of both.

Built for Heavy Loads, Big Power, and Long-Term Reliability

This package goes beyond just upgraded hardware. It includes ATS’s Co-Pilot Transmission Controller, giving you more control over shift quality and torque converter lock-up to improve drivability under load. A billet input shaft adds extra strength where it’s needed most, helping the transmission handle the increased stress that comes with tuning or heavy towing. This combination of parts works together to boost reliability and performance without sacrificing everyday drivability. ATS also makes the shipping process easy with a $500 flat rate for round-trip freight, covering both delivery and core return.
