BD Diesel 07-10 Chevy LMM 4WD Stage 4 Transmission and Converter Package

BD Diesel has been a trusted name in heavy-duty truck performance for decades, and this Stage 4 Transmission and Converter Package for your 2007-2010 Chevrolet Silverado 2500 HD LMM is one of their staples. If you're pushing your diesel's power beyond stock, especially for towing or hauling, a robust transmission upgrade is essential to handle the increased torque and keep things running smoothly. This package is designed to significantly increase the durability of your drivetrain, offering a substantial improvement over the factory setup.

This package includes a complete, matched set transmission and torque converter that have been dyno-tested together to ensure optimal performance and reliability. The transmission itself features high-energy clutch material and revised oil circuits, along with updated A & B trim valves that deliver full line pressure to the clutches. You'll find an increased clutch count across several gear sets, with C1 having 8 clutches (a 14% increase), C2 having 7 (17% increase), C3 having 6 (a notable 50% increase), and C5 also having 7 (17% increase). The torque converter is built for street and towing applications, featuring a torque-multiplying cast aluminum stator and a stamp-forged steel front cover. It offers lower RPM response than stock, leading to more efficient operation, less heat buildup, and better fuel economy. The converter also boasts up to triple the amount of lock-up clutch material for enhanced durability.

Included with every transmission is BD Diesel's own Heavy Duty deep aluminum pan, which increases oil capacity by 3.5 quarts. This extra fluid volume helps keep temperatures down during demanding use, further contributing to the transmission's longevity. For towing, street use, or track performance, when you need a dependable transmission that can stand up to your diesel's power and torque demands, this BD Diesel package is a solid choice.
