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.
