L/U Relay valve w/sleeve A340, A650

L/U Relay valve w/sleeve A340, A650 Valve Sleeve For A245E, A246E applications, this part only fits '05-later units with casting code 9132 on the upper valve body. Excess wear at the lockup relay control sleeve in some Aisin AW and Toyota/Lexus units prevents proper TCC operation and can result in various adverse symptoms. TCC apply and release concerns often develop, coupled with overheated fluid, inadequate lubrication, bushing and solenoid failure, RPM fluctuation, and converter codes. Installing Sonnax lockup relay control valve kit 77741-02K restores critical hydraulic clearances, allowing renewed TCC and lube operation. Sleeve manufactured from highly wear-resistant billet aluminum Sleeve design incorporates grooves and cross-slots to maximize valve support while maintaining proper flow Hardcoat anodized valve combats premature wear
