TransGo Performance Automatic Transmission Shift Kit - SK A750-WTA

The kit includes an oversized USA-made hardened steel TCC relay valve and bushing that restores the hydraulic circuit integrity. 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.
