High Fluid Level
WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
A fluid level that is too high may cause the fluid to become aerated due to the churning action of the rotating internal parts. This will cause foaming, loss of fluid from the vent tube, fluid level indicator tube and possible transaxle malfunction and/or damage. If an overfill reading is indicated, loosen the fluid drain plug and allow a small amount of fluid to drain and re-check fluid level.
