The C1 clutch control valve provides source pressure for control of clutch (band) apply and release. Responding to TCU and the linear solenoid, the C1 control valve will establish control timing of apply and release relative to engine torque. Bore wear will cause an overlap or premature exhaust of clutch pressure. Ream the valve bore and install the Sonnax improved valve and sleeve assembly and calibrated spring. contents: 1 clutch control valve, 1 clutch control sleeve, 1 spring - tool kit F-15471.TL25 is necessary, please order separately - follow the VB-Fix procedures published by Sonnax.
