Flare upshifts or downshift bind-ups are common problems in vehicles equipped with ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R80, 6R100 transmissions. These problems can be accompanied by a coastdown neutral condition, or pressure control out-of-range codes. The clutch control valve controls clutch apply and release timing, and problems occur when the clutch control valve wears. To fix these issues, Sonnax offers the oversized clutch A control valve kit 95740-09K to restore shift timing and vehicle drivability.
Kit is NOT compatible with ZF6HP21/28/34 (Gen.2) units. To differentiate between Gen. 1 and Gen. 2 valve bodies, see ZF Identification Guide.
Required Parts:
Symptoms:
Cause:
The clutch control valve provides source pressure for control of clutch apply and release. Responding to TCU and the linear solenoid, the clutch control valve establishes control timing of apply and release relative to engine torque. Bore wear will cause an overlap or premature exhaust of clutch pressure.Correction:
The Sonnax oversized clutch control valve, boost valve and sleeve correct circuit pressure loss and restore control timing of the clutch control A valve.You must login to post a review.
