Full Pull Diesel Performance is a trusted dealer and installer for all ATS Diesel products.   ATS Diesel backs their transmissions with a 5 year/500,000 mile warranty, and you won’t find that anywhere else.

By increasing the capability of the torque converter, clutch surface area and line pressure, the transmission can hold 200% more torque than stock. The result is a setup strong enough to handle aftermarket fueling, turbo(s), tuning and the intensity of drag racing, sled-pulling or dyno competitions. Yet, it is still smooth enough to tow and daily drive.

The Stage 2 features the addition of the ATS Co-Pilot Transmission Controller. The controller dynamically raises line pressure electronically, for additional clamping force on the clutch packs. This prevents slip under high horsepower / high torque situations, such as drag racing, sled pulling or low-speed trailer towing. Shift firmness can be adjusted with the push of a button, so the driver can adjust shift feel in a matter of seconds. The Co-Pilot is designed for trucks at any power level, but becomes crucial at 600+ hp at the tires.


The ATS Stage 2 Allison features:

  • ATS Five Star billet torque converter, featuring five lock-up clutches, a billet 12 bolt cover, mixed flow stator and custom stall speeds


  • ATS Co-Pilot Transmission Controller


  • ATS C1-C5 custom CNC?d steels and proprietary clutch pack material


  • Modified transmission pump to increase line pressure


  • Modified A&B Trim Valves

  • ATS Deep Transmission Pan featuring a 5 quart capacity over stock, finned design for heat dissipation and a magnetic drain plug
