The BD Diesel 07-10 LMM Chevy Allison Transmission & Converter Package (2WD) is engineered to enhance the durability and performance of your heavy-duty truck drivetrain. This comprehensive package includes a high-performance transmission with increased clutch counts, a deep aluminum transmission pan that adds 3.5 quarts of oil capacity, and a stage 4 upgraded torque converter designed for street and towing applications. Each component is dyno tested to ensure reliability and optimal operation under severe fleet and towing conditions. The transmission features a revised oil circuit, new A and B trim valves that deliver full line pressure to the clutches, and a new lock-up valve to boost lock-up pressures, improving efficiency and power transfer. The clutch counts have been increased significantly—C1 by 8 clutches, C2 by 7, C3 by 7, C4 by 7, and C5 by 7—resulting in up to a 75% increase over stock configurations, which translates into higher torque capacity and enhanced durability for demanding applications. The torque converter utilizes a cast aluminum stator with torque multiplying capabilities, furnace-brazed fins, and an enhanced stall speed optimized for towing and street driving, providing better fuel economy, less heat, and more efficient operation. Additionally, the billet steel front cover and high-energy clutch materials ensure long-term reliability and smooth engagement. This package is ideal for fleet operators and heavy-duty enthusiasts seeking increased power handling, improved thermal capacity, and reduced wear on critical drivetrain components. All components are assembled and tested to meet high-performance standards, making this an essential upgrade for serious towing and fleet use.
