Built to Handle Serious Power and Towing Loads

If you’ve been pushing your Duramax harder than stock parts were ever meant to handle, the BD Diesel TorqueMaster Allison 1000 Transmission and Converter Package is designed to step up where the factory setup falls short. This is a matched transmission and torque converter package that’s been dyno tested together to make sure they work in perfect harmony under heavy loads. Inside, BD upgrades the clutch packs with a higher count in every stage, giving them the holding power needed for high horsepower, aggressive throttle inputs, and big towing jobs. A billet input shaft adds the strength to withstand hard launches and the kind of torque that can snap lesser components. The heavy-duty deep transmission pan not only increases fluid capacity by 3.5 quarts but also helps keep temperatures in check, extending the life of the transmission when you’re hauling up long grades or working in hot conditions.

Precision Torque Delivery with Long-Term Reliability

The triple-disc torque converter is built to take the abuse of real-world towing, street performance, and even light competition use. Its stall speed is tuned for both street and towing applications, helping you put power to the ground smoothly without sacrificing low-end grunt. Inside, heavy-duty springs and a one-piece forged cover absorb shock and resist warping under clutch heat, while furnace-brazed turbine fins improve fluid coupling for better efficiency. Even the small details, like riveted pistons and thrust bearings instead of plastic washers, are designed for durability and smoother operation. The result is a transmission package that not only boosts performance but also improves drivability and reliability, giving you confidence every time you hook up the trailer or put your foot to the floor. And with BD’s strong warranty backing it up, you know it’s built to last.
