Air Pressure Tests

Air Pressure Tests
A no-drive condition can exist even with correct transaxle fluid pressure because of inoperative clutches or bands. Refer to the Clutch/Band Application Chart No. 601 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 fan inoperative forward clutch.
