Air Checking Transmission Clutch Operation

AIR CHECKING TRANSMISSION CLUTCH OPERATION









The ports (1 - 8), are the clutch apply passages.










When the adapter plates 10007 (1&2) are placed over the ports, proper operation of the transmission clutches can be verified. 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.










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.

1. Remove the oil pan.
2. Remove the valve body (electrohydraulic unit).Electrohydraulic Control Unit - Removal
3. Using the existing valve body (electrohydraulic unit) mounting bolts attach the Air Adapter Plates 10007 (1&2). Tighten the bolt to 8 Nm (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.
