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

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.
