Inoperative clutches can be located by substituting air pressure for fluid pressure. The clutches may be tested by applying air pressure to their respective passages after the valve body has been removed. Use Plate Set 6599-1 (1) and 6599-2 (1) to perform test .
To make air pressure tests, proceed as follows:
NOTE:
The compressed air supply must be free of all dirt and moisture. Use a pressure of 30psi.
- Remove oil pan and valve body. See Transmission and Transfer Case/Automatic - 42RLE/VALVE BODY - Removal .
- Apply air pressure to the holes in the plates (1), one at a time.
- Listen for the clutch to apply. It will give a slight thud sound. If a large amount of air is heard escaping, the transmission must be removed from vehicle, disassembled and all seals inspected.
