Valve Body Repair Kit

The TransGo SK A750-WTA SHIFT KIT® is a comprehensive valve body repair kit designed to resolve common issues in specific Toyota and Lexus automatic transmissions. It is engineered for 2003 and newer vehicles equipped with A750E/F (5-speed), A760-761E/H (6-speed), A960E (6-speed), and AB60E/F (6-speed) series automatic transmissions. Common complaints this kit addresses include shuttle shifts, bind-up or flare on the 2-3 shift, slips with throttle in 3rd and/or 4th gear, solenoid and TCC performance codes, and rough kickdown at highway speeds due to slow TCC release. These issues often stem from wear in the TCC relay valve bore, TCC control valve, and solenoid modulator valve bore, which affect hydraulic circuit integrity and pressure regulation. The kit features an oversized, USA-made hardened steel TCC relay valve and bushing to restore hydraulic circuit integrity. It also includes a redesigned, drop-in solenoid modulator valve system with a furnished bushing and valve to repair the existing worn bore without special tooling.
