TransGo Performance Automatic Transmission Shift Kit - SK U151

The kit includes a drop-in USA-made hardened steel TCC boost valve and bushing to restores the hydraulic circuit integrity. Similarly, a new redesigned drop-in solenoid modulator valve system does not require any tooling. The furnished valve, spring and bushing will restore the solenoid modulator valve function using the existing worn bore. Lastly a new drop-in USA-made hardened steel clutch apply control valve will prevent it from sticking in the bore like the OE aluminum valve does.
