Low Fluid Level
WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
A fluid level that is too low may cause the fluid to become aerated due to the churning action of the rotating internal parts.
A low fluid level could also result in poor transmission engagement, slipping, malfunction and/or damage. This could indicate a leak in one of the transmission seals or gaskets.
