Transgo A750E/F, A761E, A960E Shift Kit (Includes Required Tools) SKA750-WTA

This A750 SHIFT KIT® Valve Body Repair Kit fits 2003 and newer Toyota and Lexus vehicles equipped with the A750, A760, A761, A960 and AB60 series automatic transmissions. Common complaints with these transmissions are 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 as well as rough kickdown at highway speeds due to slow TCC release.

The first area of concern leading to the TCC complaints is a worn-out TCC relay valve bore. When the TCC relay valve bore has excessive wear, the computer can no longer control the apply slippage and the release rate of the lock-up as it is supposed to. Additionally, the TCC control valve and bushing is prone to wear causing lock-up control complaints as well.

The other area of concern is a worn-out solenoid modulator valve bore. The purpose of solenoid modulator valve is to limit the pressure going to solenoids, just like an AFL valve or solenoid pressure regulator valve does on other units. The modulating valve and spring are calibrated to prevent solenoid feed pressure from exceeding a predetermined PSI, no matter what main line pressure is. This is necessary to prevent more fluid from being fed to the solenoids than they can effectively regulate and to limit what max line pressure output is. If the pressure feeding the solenoids is too high or too low, output will also be too high or too low. Consequently, shift quality complaints, solenoid performance and gear ratio codes can occur along with low or high main line pressure.

Features and benefits:

The kit includes an oversized USA-made hardened steel TCC relay valve and bushing that restores the hydraulic circuit integrity. On the other hand, the new redesigned drop-in solenoid modulator valve system does not require any tooling. The furnished bushing and valve will restore the solenoid modulator valve function using the existing worn bore. Similarly, the new drop-in hardened steel TCC control boost valve and bushing does not require any special tooling either.

This kit also includes reusable tools to oversize the TCC relay valve bore. f you already have the tool kit order the TransGo refill kit part #A750-NTA
