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