Product Details

The ATS Diesel Trim Valve Kit is a precision-engineered performance upgrade designed specifically for 2001-2005 GM 2500/3500 trucks equipped with the Allison LCT1000 5-speed automatic transmission and 6.6L Duramax diesel engines (LB7/LLY).

The control center of a transmission is the valve body, controlling transmission operation, torque converter control, shift feel and ultimately, transmission reliability. ATS re-engineered Allison valve bodies and trim valves from the ground up, resulting in a comfortable, yet confidence-inspiring shift and increased holding capacity.

Key Features:

  • Engineered for Allison LCT1000 5-speed transmissions (2001-2005 GM applications)
  • Improves transmission control and shift quality
  • Increases line pressure for enhanced torque capacity
  • Enhances transmission durability for towing, performance driving, and daily use
  • Precision-manufactured components for reliable operation

This trim valve kit is an essential component in ATS transmission builds and master overhaul kits, delivering improved hydraulic control for better transmission performance under increased power levels. Ideal for diesel enthusiasts who demand enhanced shift firmness and transmission reliability from their Duramax-powered trucks.
