Description

The Pacific Performance Engineering 128041000 is a pressure calibration kit designed for 2001-2010 GM 6.6L Duramax trucks with Allison 1000-2000 transmissions. It increases line pressure, which improves clutch holding ability and promotes tighter shifts.

This kit is recommended for trucks that haul heavy loads or make high horsepower, serving as an upgrade when building a 5 or 6 speed Allison 1000 transmission.
