TransGo Performance Automatic Transmission Shift Kit - SK U660E

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 bushing and valve will restore the solenoid modulator valve function using the existing worn bore. Lastly, the drop-in USA-made hardened steel B2 Control vale utilizes an unworn area of the bore restoring the circuit integrity.
