SonnaxValve Body Kit

The boost valve assembly is designed to increase line pressure in Drive and Reverse. When the Aisin AW 450-43LE sleeve is worn on the inside or loose within the valve body, boost or EPC fluids can leak to exhaust or cross-leak and increase forces on the valve. Leakage to exhaust reduces line rise, while the cross-leaks can result in broken clutch drums or cases. Sonnax main boost valve kit 94987-09K has upgraded materials to prevent wear and restore proper hydraulic control. Sleeve is manufactured from highly wear-resistant billet aluminum Hardcoat anodized aluminum valve combats premature wear Restores proper hydraulic sealing and OE pressure control Drop-in Zip Valve™ parts install quickly and easily
