Harsh Engagement when Shifting into Reverse or Drive - Irregular Shifting while Driving on Ford E-150

Problem Description and Possible Solution

On vehicles equipped with the E4OD (4-speed automatic) transmission, harsh engagement of the automatic transmission when shifting into reverse or drive, and irregular shifting while driving can be caused by failure of the Manual Lever Position (MLP) sensor. Water intrusion can lead to failure of the sensor, which should be replaced with a revised sensor and wiring kit to prevent future failure.
