TRANSAXLE - CD4E - FLUID LEAK FROM PUMP BODY SEAL

FORD:
1994-95 PROBE
1995 CONTOUR

LINCOLN-MERCURY:
1995 MYSTIQUE

ISSUE:
Some vehicles may leak fluid from the pump-to-case interface area of the transaxle. This may be caused by the pump body seal being rolled or pinched during installation.

ACTION:
If a fluid leak is detected in the pump-to-case interface area, refer to the following service procedure to replace the pump body seal.

This procedure does not require complete teardown of the transaxle and should only be used for leak concerns. If replacement of the pump body or pump support is required, the transaxle must be disassembled and reassembled following the Service Manual procedure. The components will be misaligned if this repair is performed while the transaxle is still in the vehicle.
