High Performance Valve Body Upgrade for Allison 1000 Transmission

Upgrade your 2001-2004 GM 6.6L Duramax LB7 with the RevMax Allison 1000 High Performance Valve Body Upgrade, designed to enhance your transmission's performance and durability. This upgrade is perfect for both modified and stock engines, offering increased transmission durability, lower operating temperatures and improved efficiency, all in a simple and effective package. Whether you’re looking to shave seconds off your 1/4 mile time or simply enhance your truck’s daily drivability, this valve body upgrade delivers crisp, precise shifts without the neck-snapping jolt. Specially calibrated for use with RevMax Level 2, 3, 4, and 5 torque converters, this valve body can also be used with other manufacturers' torque converters. Each unit undergoes a thorough hand-washed cleansing process to remove all metal and clutch particles, followed by a premium solvent cleaning. Hand-assembled by qualified and caring professionals, the valve body features a custom reprogramming shift kit, increased line pressure, and modified fluid passages.

Durable Construction & Design

With orifice diameters changed and custom high-performance shift valves and spring assemblies, you’ll experience shortened shift times and increased torque converter lockup apply pressure. The valve body also includes new O-rings, sealing rings, and gaskets, ensuring a reliable and leak-free connection. Each valve body undergoes complete computerized testing on RevMax's Dyno, ensuring optimal performance before it reaches your hands. Please note that the pan gasket and filter are not included. With increased durability, lower temperatures, and faster shift times, your Duramax LB7 will be more efficient and reliable, whether on the street or the strip.

Fits: 2001-2004 GM 6.6L Duramax LB7 with Allison 1000
