Symptoms:

  • Hydraulic-related converter codes
  • TCC apply & release concerns
  • Low cooler & lube pressure

Cause:

Severe wear of the valve body bore at the bypass clutch control valve allows regulated converter charge oil leakage.

Correction:

Sonnax oversized bypass clutch control valve is slightly oversized to restore hydraulic integrity at the spool/bore interfaces.

Vehicles with Ford AXODE or AX4S transmissions often exhibit converter clutch apply and release problems, which are most affected by high operating temperatures. These problems can be caused by severe wear of the valve body bore at the bypass clutch control valve, which allows regulated converter charge oil leakage. If the valve bore is worn, converter feed and lube oil will exhaust and MCCC (modulated converter clutch control) solenoid control is lost. This oil is fed to the lube circuit and cooler, and helps maintain the TCC in the release position. Sonnax oversized bypass control valve kit 96201-19K corrects these problems.

  • Annular grooves have been added to the TCC solenoid spool lands to help center the valve in the bore
  • Hardcoat anodized aluminum valve combats premature wear
  • Valve is slightly oversized to restore hydraulic integrity at the spool/bore interface
  • A sturdier spring for the control sleeve is included in each kit to offer a stronger resistance to the oversized valve
  • A bore sizing tool is included in each reamer kit to ensure proper fit and bore integrity after reaming

It is strongly recommended that Sonnax bypass TCC control plunger valve kit 96206-01K be installed along with this kit.
