This TransGo 6L80 TCC Regulator Valve Kit fits 2006 and later General Motors and BMW vehicles equipped with 6L45, 6L50, 6L80 and 6L90 automatic transmissions. The TransGo drop-in redesign USA-made hardened steel TCC regulator valve, features longer lands which restore the hydraulic integrity of the circuit by utilizing previously unused and therefore unworn areas of their bore. In addition, the special design valve and spring calibration enables the computer to control the TCC regulation more accurately, which results in better slip control. Lastly, the drop-in USA-made hardened steel clutch select valves greatly help prevent the valves from sticking in their bores.
