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 ATS Stage 1 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 C1-C5 custom CNC’d steels and proprietary clutch pack material
  • Modified transmission pump to increase line pressure
  • Modified A&B Trim Valves
  • New gaskets and seals
  • ATS Deep Transmission Pan featuring a 5 quart capacity over stock, finned design for heat dissipation and a magnetic drain plug
