Symptoms:

  • Downshift bind-ups
  • Flare shifts
  • Excess clutch overlap & clutch distress
  • Pressure control out-of-range codes

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.

Flare upshifts or downshift bind-ups are common problems in vehicles equipped with ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R80 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.

  • Hard-coat anodized aluminum clutch control and boost valves resist wear and fit tighter to the bore than OE for better sealing
  • Boost sleeve is highly wear-resistant to increase life
  • F-95740-TL8 tool kit can be used for both 95740-08K and 95740-09K oversized valve kits

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.

A vacuum test at the inner port does not hold 18 in-hg of vacuum. If the outer port does not hold 16 in-hg of vacuum, but the inner port does hold 18 in-hg, use either this oversized kit 95740-09K or clutch A control boost valve and sleeve kit [95740-21K].
