Clutch Air Pressure Tests: Notes
Inoperative clutches can be located using a series of tests by substituting air pressure for fluid pressure using (special tool #10383, Plate, Clutch Pressure Test).
The clutches may be tested by applying air pressure to their respective passages. The valve body must be removed. To make air pressure tests, proceed as follows:
The compressed air supply must be free of all dirt and moisture. Use a pressure of 5-8 bar (73-116 psi).
Remove the oil pan and the valve body. Install (special tool #10383, Plate, Clutch Pressure Test) and tighten bolts to 6 N.m (50 in. lbs.). When testing is finished install valve body and tighten new bolts to 8 N.m (71 in. lbs.). Install the oil pan bolts and tighten to 10 N.m (89 in. lbs.). Fill the transmission. Refer to FLUID AND FILTER, STANDARD PROCEDURE .
