Oversized Bypass Clutch Valve Kit

OVERSIZED BYPASS CLUTCH VALVE KIT

OE valve name: WD-V. Tool Required.

Symptoms:

  • TCC codes
  • Excess TCC slip
  • Cycling RPM
  • Low TCC release pressure
  • Flare shifts
  • Harsh shifts
  • Rough idle in Reverse
  • Overheated converter

Cause:
The bypass clutch control valve controls torque clutch apply and release pressure. As the bore wears, the apply rate of the clutch slows and the clutch release pressure will not vent.

Correction:
Ream the bore to restore tolerance and install the upgraded Sonnax oversized bypass clutch control valve kit.


Common problems in vehicles equipped with ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R80 transmissions include torque converter clutch slip, firm shifts and an overheating torque converter. One cause of these problems is a worn bypass clutch control valve resulting in slow applyand release of the torque converter clutch. Installing the Sonnax oversized bypass clutch control valve kit restores factory torque converter clutch apply and release rates. This will resolve the converter slip, harsh shift and overheating problems.

  • Hard-coat anodized aluminum valve resists wear
  • Valve is tighter fit to the bore than OE for better sealing
  • Valve has annular grooves for better centering in the bore

Note:
Kit is NOT compatible with ZF6HP21/24/34 (Gen.2) units.
