Symptoms:

  • Excess TCC slip RPM & related codes
  • Harsh TCC apply & release
  • Low TCC release pressure
  • Rough idle in Reverse
  • Harsh downshifts
  • Flare shifts
  • Overheated converter

Cause:

The converter release regulator valve provides lube pressure regulation and contributes to the timing of the converter clutch apply/release action. Bore wear will cause converter clutch slippage and related codes and affect lockup clutch apply and release quality.

Correction:

Installing the Sonnax wear-resistant oversized valve restores circuit pressure regulation and control timing of the converter clutch apply/release action.

In ZF6 & Ford 6R applications listed above, the oversized converter release regulator valve provides lube pressure regulation and contributes to the timing of the converter clutch apply/release action. Significant bore wear can allow release or apply pressures to leak to sump, which results in converter clutch slippage and related codes. This can affect lockup clutch apply and release timing and feel. Installation of the Sonnax oversized converter release regulator valve kit 95740-05K restores circuit pressure regulation and control timing of the converter clutch apply/release action.

  • Valve is hard-coat anodized to reduce wear
  • The tuned spring included maintains OE operating pressures with the new oversized valve
