BD Diesel TorqueMaster 01-04 Chevy LB7 Stage 5 Allison Trans & Converter Package - 4WD

BD Diesel is known for building tough drivetrain components for demanding diesel applications. If you're looking to upgrade your 2001-2004 Chevrolet Silverado 2500 HD's Allison transmission to handle more power and torque, this Stage 5 package is a solid choice. It includes a matched transmission and torque converter set that's been dyno tested together to ensure they perform reliably as a unit.

This package features a billet input shaft designed to withstand the stress of rapid throttle changes and high horsepower. The transmission itself has an increased clutch count across several drums – C2, C3, C1, C4, and C5 all see more clutches than stock, with C3 getting a significant 75% increase. This means more surface area for engagement, leading to better power handling and reduced heat buildup. The trapezoid teeth design on the clutch plates also helps reduce wear and chatter. You also get BD's aluminum heavy-duty deep transmission pan, which adds 3.5 quarts of fluid capacity, helping to keep temperatures down and extending the life of the transmission.

The included triple-disc torque converter is enhanced for street and towing applications, with a cast stator design to maximize torque transfer and a taller cover that allows for more rebuilds. Furnace brazed turbine fins improve fluid coupling efficiency, and new sprag components are included for long-term durability. This entire package is designed to increase the durability of your drivetrain, whether you're towing heavy loads or hitting the track.
