In GM 4T60 and 4T60-E units, the TCC apply valve acts as the switch valve for converter apply and release. The TCC regulator valve 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. 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. Reconditioning the bore and installing Sonnax oversized TCC apply valve kit 84754-16K restores hydraulic integrity.

PTFE seal prevents loss of signal oil that strokes the valve
Oversized versions available to restore the valve body bore
Standard-size versions are drop-in replacements and do not require valve body removal
