ISSUE: The separator plate lower gasket from the current gasket service kit (7153) and overhaul service kit (7C391) cannot be used on any 1990 model vehicles.

ACTION: When servicing 1990 AOD transmissions the separator plate lower gasket found in the current kits must be thrown away and replaced with a new gasket (F0AZ-7D100-A). This new gasket can only be used on 1990 vehicles.
CAUTION: USE OF THE SEPARATOR PLATE LOWER GASKET CONTAINED IN THE CURRENT KITS ON 1990 VEHICLES COULD CAUSE A REDUCTION IN THROTTLE VALVE PRESSURE. THIS CAN RESULT IN POSSIBLE TRANSMISSION FAILURES.

In the near future, gasket and overhaul kits will no longer contain any main control gaskets. Two main control lower separator plate gasket items will be available. Refer to the following gasket application chart for correct service part usage.
