The BD Diesel 1064724 Transmission for 2004.5-2006 Chevy LLY Allison 1000 5-speed 4WD is engineered for heavy-duty performance and durability. This transmission features a revised oil circuit design, enhanced clutch counts, and stronger internal components to handle up to 300% more power and torque than the stock transmission. It includes a BD rigid aluminum heavy-duty transmission pan, which increases oil capacity by 3.5 quarts, reduces case flex, minimizes internal oil leaks, and incorporates heat-dissipating fins to keep operating temperatures down. The magnetic drain plug facilitates easier maintenance and debris collection, supporting long-term drivetrain health.
This transmission is equipped with new components such as a convertor lock-up valve to improve lock-up pressures, high-energy GPZ frictions for smooth engagement, and modified power pistons, springs, and pressure regulation systems to optimize performance. The clutch count has been increased across all clutch packs, with C1 at 8, C2 at 7, C3 at 7, C4 at 7, and C5 at 7 clutches, providing greater holding capacity and durability. The upgraded oil regulation and revised internal circuits contribute to consistent, crisp shifts and enhanced reliability under severe towing and heavy-duty conditions.
Each unit undergoes extensive dyno testing to ensure performance standards are met. The transmission includes a 36-month or 150,000-mile limited warranty, and features high-energy GPZ frictions, a pressure-loc system, and stronger internals to withstand increased torque loads. It is designed specifically to increase the longevity of your drivetrain, making it ideal for fleet and heavy-duty applications requiring reliable, high-capacity transmission performance.
Features:
- Heavy-duty design with increased clutch counts and stronger internals for enhanced torque capacity
- Premium high-energy GPZ frictions and increased friction surface area for smooth, reliable engagement
- Revised oil circuits and heat-dissipating pan with added capacity to prevent overheating and slippage under severe towing
