ATS Allison Performance Valve Body for Chevy/GMC (2001-02) 6.6L Duramax LCT1000

This ATS valve body for the LCT1000 in 2001-2002 GM Duramax replaces the factory unit with one ATS has reworked for firmer, more consistent shifts and the line pressure needed to hold added power. The valve body controls how and when the transmission applies each clutch, so it is one of the most effective upgrades for a transmission that slips, flares, or shifts soft.

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.
