Enhance the durability and performance of your heavy-duty truck with the BD Diesel 1064734SS transmission and torque converter package designed specifically for 2006-2007 Chevrolet Silverado 2500 HD, 3500 HD, and GMC Sierra 2500 HD, 3500 HD 4WD models equipped with the LBZ engine. This comprehensive package features a high-capacity aluminum deep transmission pan that increases oil capacity by 3.5 quarts, promoting better cooling and lubrication under severe towing or hauling conditions. The transmission assembly includes revised oil circuits, a new lock-up valve to boost lock-up pressures, and a double cage stator sprag to improve torque multiplication and reduce common failure points, ensuring a longer service life for your drivetrain. Each transmission is dyno tested to verify performance and reliability before installation. The clutch system has been upgraded with increased clutch counts—C1 8 clutches, C2 7 clutches, C3 7 clutches, C4 7 clutches, and C5 7 clutches—delivering up to a 75% increase in clutch capacity over stock, which significantly improves holding power and shift quality. The torque converter features enhanced stall characteristics optimized for street and towing applications, with a cast aluminum stator for efficient torque multiplication and furnace-brazed fins for superior heat dissipation. This converter offers a lower rpm response for improved throttle response and fuel economy, with up to triple the lock-up clutch material for durability. Equipped with a stamp-forged steel front cover, this converter provides additional strength and reliability. This package is engineered to increase drivetrain durability, reduce heat, and improve fuel efficiency, making it ideal for heavy towing, fleet services, or high-performance applications. Each component is designed to meet or exceed OE standards, providing long-term operational reliability and performance for your heavy-duty truck.
