With the use of Air Adapter Plates 10007-1,10007-2, air-pressure testing can be used to check transmission 
clutch operation. The test can be conducted with the transmission either in the vehicle (where applicable) or on 
the work bench, as a final check. 

Air-pressure testing requires that the oil pan and valve body be removed from the transmission.

1. Remove the oil pan.  

2. Remove the valve body (electrohydraulic unit). See REMOVAL.  

3. Using the existing valve body (electrohydraulic unit) mounting bolts attach the Air Adapter Plates 10007-

1, 10007-2. Tighten the bolt to 8 N.m (71 in. lbs.).  

4. Apply 30 psi of air pressure to each port  

If the clutch is functioning, a soft thump will be heard as the clutch is applied. The clutch application can also 
be felt by touching the appropriate element while applying air pressure. As the air pressure is released, the 
clutch should also release.

NOTE:

The air supply which is used must be free of moisture and dirt. Use a pressure 
of 30 psi to test clutch operation.

NOTE:

When checking the K1 clutch , air must pass through numerous passages to 
reach the clutch it's self, therefore only a slight application will be noted.
