Description

The Calibrated Power 6 Speed Conversion Kit is designed to upgrade Allison transmissions in 2001-2005 LB7 and LLY Duramax trucks. This kit adds a sixth gear, reducing highway cruising RPMs by approximately 300 RPM (a 14% reduction). It also aims to improve fuel economy and reduce cabin noise and exhaust drone.

The conversion includes custom TCM tuning for your specific truck, a new valve body, wiring harness, and solenoids. The kit is compatible with high idle controllers and the gear indicator works with an Edge CTS monitor. The manufacturer requires your vehicle's VIN, tire size, and turbo type to be provided during checkout.
