This TSB article is being republished in its entirety to update the model year coverage, add a concern to the title, and revise the Service Procedure.
ISSUE
Automatic transmission fluid may be seeping from the grommet-style vent assembly and down the main control cover or may be leaking fluid from the fluid fill tube on some vehicles. The appearance of fluid on the main control cover may be misdiagnosed as a leak in the cooler line and/or main control cover gasket.
ACTION
Diagnose leak and repair by referring to the following Service Procedure for details.
NOTE
BEGINNING JANUARY 1997, ALL CD4E TRANSAXLES CONTAIN A REVISED MAIN CONTROL COVER (F7RZ-7G004-AA), FIGURE 1, AND VENT TUBE ASSEMBLY (F7RZ-7034-CA FOR PROBE AND F7RZ-7034-BA FOR CONTOUR/MYSTIQUE), FIGURE 2. THIS NEW DESIGN WILL PREVENT FLUID FROM SEEPING FROM THE VENT. IF THE VENT HOSE IS KINKED OR BLOCKED INTERNALLY, FLUID WILL LEAK FROM THE TRANSAXLE FILL TUBE.
For 1995-1997 Contour/Mystique Vehicles Built With Grommet-Style Vent Assembly Main Control Cover:
NOTE
BEFORE INSTALLING NEW VENT TUBE, PURGE ANY OBSTRUCTION FROM THE HOSE LINE USING LOW PRESSURE AIR SUPPLY. HIGH PRESSURE CAN BLOW PAST ANY OBSTRUCTION WITHOUT EVACUATING THE HOSE. WHEN INSTALLING THE HOSE, FOLLOW THE INSTRUCTION SHEET PROCEDURE WITH THE VENT TUBE KIT, ENSURING THE HOSE IS NOT KINKED.
If fluid is detected on the main control cover near the vent and the area around the grommet is damp, check the transmission fluid level. If the fluid level is below the crosshatched area, check for alternate leaks. If the fluid level is between the crosshatched area, service with Remote Vent Kit (F6RZ-7034-AA).
If replacement of a main control cover is required, replace with a new Main Control Cover (F7RZ-7G004-AA) and a Vent Tube Assembly (F7RZ-7034-BA).
For 1994-1997 Probe Vehicles:
NOTE
BEFORE INSTALLING NEW VENT TUBE, PURGE ANY OBSTRUCTION FROM THE HOSE LINE USING LOW PRESSURE AIR SUPPLY. HIGH PRESSURE CAN BLOW PAST ANY OBSTRUCTION WITHOUT EVACUATING THE HOSE. WHEN INSTALLING THE HOSE, FOLLOW THE INSTRUCTION SHEET PROCEDURE WITH THE VENT TUBE KIT, ENSURING THE HOSE IS NOT KINKED.
Transaxles built with grommet-style vent assembly main control cover CANNOT be serviced with the new main control cover. If cover replacement is required, service with the grommet-style vent assembly Main Control Cover (F4RZ-7G004-A).
If repairing a vent seeping problem on the grommet-style vent assembly main control cover, use the Remote Vent Kit (F6RZ-7034-BA).
For 1997 Probe, 1998-2000 Contour/Mystique, And 1999-2000 Cougar Vehicles:
NOTE
BEFORE INSTALLING NEW VENT TUBE, PURGE ANY OBSTRUCTION FROM THE HOSE LINE USING LOW PRESSURE AIR SUPPLY. HIGH PRESSURE CAN BLOW PAST ANY OBSTRUCTION WITHOUT EVACUATING THE HOSE. WHEN INSTALLING THE HOSE, FOLLOW THE INSTRUCTION SHEET PROCEDURE WITH THE VENT TUBE KIT, ENSURING THE HOSE IS NOT KINKED.
Vehicles built with the new designed main control cover must use the new Main Control Cover (F7RZ-7G004-AA) and/or new design Vent Tube Assembly (F7RZ-7034-CA for Probe, F7RZ-7034-BA for Contour/Mystique) if replacement is required.
NOTE
FOR PROBE APPLICATIONS ONLY, THE NEW DESIGN MAIN CONTROL COVER AND NEW DESIGN TUBE ASSEMBLY CANNOT BE INSTALLED ON PREVIOUS MODEL VEHICLES DUE TO A REVISED AIR CLEANER DESIGN.
