BD Diesel 06-07 Chevrolet LBZ 4wd Trans & Converter Stage 4 Package

Doing a transmission swap on your 2006-2007 LBZ Duramax truck? This BD Diesel Stage 4 Trans & Converter Package is built to handle the increased power and torque demands that come with a modified diesel. It's a complete matched set, meaning the transmission and torque converter have been dyno-tested together to ensure they work seamlessly for ultimate performance and reliability. This package is designed to significantly increase the durability of your drivetrain, making it a solid choice for towing, street driving, or even track use.

The transmission itself features an aluminum HD deep pan that adds an extra 3.5 quarts of oil capacity, which helps keep temperatures down. Inside, you'll find high-energy clutch material, revised oil circuits, and updated valves that deliver full line pressure to the clutches. Specifically, the clutch counts have been increased across several drums: C1 has 8 clutches (a 14% increase), C2 has 7 clutches (a 17% increase), C3 has 7 clutches (a 75% increase), and C5 has 7 clutches (a 17% increase). The torque converter is enhanced for street and towing applications, featuring torque-multiplying cast aluminum stators and a stamp-forged steel front cover. It offers lower RPM response than stock, more efficient operation, and up to triple the amount of lock-up clutch material for improved durability and less heat generation.

This package is a comprehensive upgrade for your LBZ. It includes the transmission, a complete torque converter, and the heavy-duty pan. BD Diesel backs this package with a 36-month/150,000-mile parts warranty and a 12-month/24,000-mile labor warranty, giving you confidence in your investment.
