Air-pressure testing can be used to check transmission clutch and brake operation. The test can be conducted with the transmission either in the vehicle 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 400 - 500 kPa (58 - 72 psi) to test clutch operation.
Apply air pressure at each port. If the clutch or brake is functioning, a soft thump will be heard as the clutch or brake is applied. The clutch or brake application can also be felt by touching the appropriate element while applying air pressure. As the air pressure is released, the clutch or brake should also release.
