BD Diesel 04-06 Chevy Silverado / GMC Sierra 6.6L 4WD Roadmaster Transmission & Converter Package

Already running headers and a tuner on your 6.6L Duramax? This BD Diesel Roadmaster transmission and converter package is the next piece of the puzzle for a more reliable drivetrain. Designed specifically for the 2004-2006 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD, this package addresses common weak points in the stock Allison transmission, giving you peace of mind whether you're towing heavy loads or just want a more robust setup.

BD Diesel has beefed up the internal clutch packs, notably doubling the capacity of the C2 and C4 clutches. This means less slip under load and improved durability, especially when you're putting your truck to work. To help manage the heat generated by increased power and towing, the transmission comes with a deep aluminum pan that adds an extra 3.5 quarts of fluid capacity. More fluid means lower operating temperatures, which is crucial for transmission longevity. The package also includes a billet ProForce torque converter, built for reliable engagement and to handle the increased torque capacity of the transmission.

Every Roadmaster Allison transmission is dyno tested before it leaves BD Diesel, so you know it's ready to go. This is a complete package designed to bolt in and provide a significant improvement in reliability and performance for your Duramax truck.
