Symptoms:

  • Flare shifts
  • Neutral shifts
  • Harsh upshifts
  • Harsh downshifts
  • Gear ratio codes
  • Solenoid performance codes
  • Delayed Forward
  • Delayed Reverse
  • Wrong gear starts
  • TCC slip

Cause:

Excess solenoid pressure regulator valve to bore clearance may cause shift and pressure problems. All the linear solenoids are fed by this regulator valve. Shift quality depends on the amount of wear and often changes with operating temperature.

Correction:

The oversized solenoid pressure regulator valve will control the minimum and maximum pressure source for the solenoid.

In ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R80 units, the variable force solenoids control clutch apply/release, torque converter clutch apply/release and line pressure. The solenoid pressure regulator valve ensures proper flow and pressure to the solenoids during hot conditions and low pressure. Low feed pressure at idle can create delayed engagement or wrong gear starts. This valve also limits the maximum pressure to all the solenoids. Excessive solenoid feed pressure can flood the solenoids, causing gear ratio codes, harsh up/downshifts and excessive line pressure.

  • Hard-coat anodized aluminum valve resists wear
  • New matching spring reproduces OE function with the oversized valve

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.
