The Transmission Does Not Shift Correctly out of First Gear on Ford E-150

Problem Description and Possible Solution

This concern related to the 4R100 automatic transmission typically seen mated to the 5.4L V8. If the transmission does not shift correctly out of first gear, a “one-way” clutch inside the transmission may have failed. If the transmission fluid condition is good, and other failures are not found upon transmission tear down, the one-way clutch may be replaced along with the drum and friction plates. Our technicians note this is a major internal transmission repair.
