Product Details
4T60, 4T60E. The TCC apply valve acts as the switch valve for converter apply and release. The TCC regulator valve (84754-01K & -08K) controls TCC apply pressure. Both the apply valve and the regulator valve can cause slip codes. When the apply valve is worn, it often returns to the un-apply position even though the TCC apply solenoid remains energized. Check for changes in slip RPM with a scanner or changes in cooler flow with the Sonnaflow FM-01KA. Generally the apply valve causes larger changes in slip RPM as the converter cycles from apply to full release. The regulator valve causes a more gradual load and heat-sensitive slip.
