BD Diesel Duramax Allison Transmission & Converter Package – Part # 1064724BM

The BD Diesel Duramax Allison Transmission & Converter Package with part number 1064724BM is a comprehensive solution designed to meet the demanding needs of heavy-duty diesel applications. Engineered for reliability and performance, this package combines a dyno-tested transmission with a high-performance torque converter, ensuring optimal power transfer and durability under severe towing, street, or track conditions. The transmission features a BD aluminum heavy-duty deep pan that increases oil capacity by 3.5 quarts, enhancing cooling and fluid longevity. This design also reinforces case strength to withstand high torque levels, making it ideal for fleet and performance vehicles.
The transmission is equipped with a variety of upgraded components, including riveted pistons for better alignment and vibration reduction, a self-centering trapezoid teeth design to increase contact area, and a billet input shaft capable of handling rapid throttle inputs and high horsepower. The clutch system has been significantly improved with increased clutch counts—up to 8 clutches in the C1 carrier—and high-energy friction materials for smoother engagement and enhanced durability. Furnace brazed turbine fins and revised oil circuits optimize fluid coupling efficiency and heat dissipation, further extending component life.
This package also features a new converter lock-up valve to improve lock-up pressures, reducing slip and improving fuel efficiency. The torque converter itself is a triple disc design with an enhanced stall speed, tailored for both street and towing applications. High-quality thrust bearings replace plastic washers, contributing to long-term drivetrain reliability. Additional features include furnace brazed fins, a stamped forged one-piece cover, and a cast stator design that maximizes torque capacity. Each transmission is dyno tested before shipment to ensure performance standards are met, providing a dependable upgrade for your Chevrolet Silverado 2500 HD equipped with a Duramax engine from 2004.5 to 2006.
This package is essential for fleet operators and enthusiasts seeking improved shift quality, increased torque capacity, and long-lasting performance in their heavy-duty diesel trucks, making it a reliable choice for demanding applications and severe duty cycles.
