High Performance Rebuilt Valve Body Upgrade for GM 6.6L LBZ/LMM

Upgrade your 2006-2010 GM 6.6L Duramax LBZ/LMM with the RevMax Allison 1000 High Performance Rebuilt Valve Body Upgrade. This enhancement is designed to boost the performance, efficiency, and durability of your transmission, making it an ideal choice for both stock and modified engines. Whether you're looking to improve your vehicle's performance on the street or the strip, this valve body upgrade provides quicker, smoother shifts without all of the harshness. With custom high-performance shift valves and spring assemblies, as well as altered orifice diameters, the valve body delivers shorter shift times and increased torque converter lockup apply pressure. It includes new O-rings, sealing rings, and gaskets where necessary to ensure a secure, leak-free installation. The mounting surface is checked and flat-filed, and all threads are inspected and repaired to ensure a perfect fit.

Durable Construction & Design

Calibrated specifically for use with RevMax Level 2, 3, 4, and 5 torque converters, this valve body is also compatible with other manufacturers' torque converters. The unit is completely disassembled and meticulously cleaned by hand to remove all metal and clutch particles. A solvent cleaning ensures every component is spotless before reassembly. Skilled professionals hand-assemble the valve body, incorporating a custom reprogramming shift kit, increased line pressure, and modified fluid passages for optimal performance. By reducing transmission temperatures and increasing durability, the RevMax ensures your Duramax LBZ/LMM operates at peak efficiency, providing smoother and more efficient shifts for daily driving or competitive racing.
