ISSUE:

Some vehicles equipped with the E4OD/4R100 transmission may exhibit the torque converter external access dust plug dislodging and falling out during severe duty use. This may be caused by a combination of stack up tolerance, material shrinkage over time, and loading being applied to the plug during usage or cleaning of the underside of the vehicle.

ACTION:

Obtain new plug (E9TZ-7N171-A) and apply 1/4″ bead of silicone sealant around entire perimeter of part and install plug into transmission case. The silicone is to be applied in the groove of the part such that when it is installed, the sealant will fill any gaps between the transmission case and the plug.

SERVICE PROCEDURE

  1. Obtain service part E9TZ-7N171-A, F7TZ-19554-AA and general purpose degreaser such as Motorcraft Brake Parts Cleaner, PM-4.
  2. Clean transmission case casting in the area of the plug using general purpose degreaser making sure the area is free from grease and other contaminants.
  3. Apply a 1/4″ bead of silicone sealant F7TZ-19554-AA to plug E9TZ-7N171-A making sure that the groove in the plug is filled with silicone sealant.
  4. Immediately install plug into the transmission case casting smoothing out any overflow that may occur during installation.
