BD Diesel 1030472 Allison 1000 Valve Body 6-Speed LBZ/LMM Duramax

The BD Diesel 1030472 is a high-performance exchange valve body designed specifically for 2006-2010 GM 6.6L Duramax LBZ/LMM engines equipped with 6-speed Allison 1000 transmissions. When you upgrade your engine with performance parts, the factory transmission struggles to handle increased horsepower and torque—especially during towing and acceleration. This upgraded valve body provides an instant performance boost to ensure your transmission can handle enhanced engine output.

Key Features:

• Complete valve body assembly with integrated shift kit pre-installed
• Hand-lapped mating surfaces to eliminate irregularities and prevent internal leakage
• New trim valves that increase mainline and clutch apply pressures for greater clamping force
• Revised valve design with new springs and larger oil ports
• Proprietary governor piston dimensions for optimized performance
• Includes four solenoids: Pressure Control A (TRIM A), Pressure Control B (TRIM B), TCC PWM, and Main Mod (G Solenoid)

Performance Benefits:

• Improved shift quality and firmer gear changes
• Increased clutch holding capacity to handle 90-120 rear wheel horsepower gains
• Reduced clutch slippage and friction for extended transmission life
• Ideal for moderate towing applications and performance builds
• Cost-effective alternative to complete transmission rebuilds
