A750 SHIFT KIT® Valve Body Repair Kit for Toyota and Lexus
This comprehensive A750 SHIFT KIT® Valve Body Repair Kit is designed for Toyota and Lexus vehicles from 2003 onwards, equipped with A750, A760, A761, A960, and AB60 series automatic transmissions. Owners often report issues such as shuttle shifts, bind-up or flare during the 2-3 shift, slips in 3rd and/or 4th gear under throttle, various solenoid and TCC performance codes, and rough kickdown at highway speeds due to delayed TCC release.
Key concerns include the wear of the TCC relay valve bore, leading to the computer's inability to control the lock-up's apply slippage and release rate. Additionally, wear in the TCC control valve and bushing can cause lock-up control issues. Another critical area is the solenoid modulator valve bore wear, which affects the regulation of pressure to the solenoids, impacting shift quality, solenoid performance, and gear ratio codes, along with fluctuating main line pressure.
Features and Benefits:
- The kit features an oversized, USA-made hardened steel TCC relay valve and bushing, restoring hydraulic circuit integrity.
- A redesigned, easy-to-install solenoid modulator valve system requires no special tooling. The included bushing and valve utilize the existing worn bore for restoration.
- The kit also contains a new drop-in hardened steel TCC control boost valve and bushing, simplifying installation without special tools.
- Reusable tools for oversizing the TCC relay valve bore are included. For those who already have the tool kit, a TransGo refill kit (part # A750-NTA) is available.
