This upgrade is specifically designed to improve the performance, efficiency, and durability of your transmission, making it an excellent choice for both modified and stock engines.

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 is completely disassembled and undergoes a thorough hand-washed cleansing process to remove all metal and clutch particles. Additionally, a premium solvent cleaning ensures every part is spotless before reassembly. Hand-assembled by highly skilled professionals, the valve body features a custom reprogramming shift kit, increased line pressure, and modified fluid passages to optimize performance.

Durable Construction & Design

Custom high-performance shift valves and spring assemblies, along with changed orifice diameters, contribute to shortened shift times and increased torque converter lockup apply pressure. This upgrade also includes new O-rings, sealing rings, and gaskets where applicable, ensuring a secure and leak-free installation. What's more, the mounting surface is verified and flat-filed, and all threads are checked and repaired to guarantee a perfect fit. Each valve body is then subjected to complete computerized testing on RevMax's Zoom VBT4000 Valve Body Dyno to ensure optimal performance. Please note that the pan gasket and filter are not included.
