ATS Transmission Package for Chevy/GMC (2004.5-05) Allison LCT1000 6.6L LLY 4X4 Duramax, Stage 3 (with PTO)

This ATS Stage 3 Allison LCT1000 transmission package is a complete, matched drivetrain upgrade for 2004.5-2005 GM 6.6L Duramax 4WD trucks with PTO. Everything in the package is built by ATS to work together, so you are not mixing a built transmission with a stock converter or controller. Higher stages are built for more horsepower and heavier use, so match the stage to your power level and how you use the truck.

ATS Diesel Performance has built diesel transmissions and performance parts since 1993. ATS designs, engineers, and manufactures most of its products in-house at its Arvada, Colorado facility, and tests them at altitude on the same long grades its customers tow on.
