Air Pressure Tests: Notes
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
A no-drive condition can exist even with correct transmission fluid pressure because of inoperative clutches or bands. Refer to the BAND AND CLUTCH APPLICATION (A) and BAND AND CLUTCH APPLICATION (B) to determine the appropriate elements. A clutch concern can be located by substituting air pressure for oil pressure to determine the location of the malfunction.
For example, when the transaxle range selector lever is in a forward gear range ((D), 2, 1), a no-drive condition can be caused by an inoperative forward clutch.
