3RD Clutch Hydraulic Circuit Air Check

To air check 3rd clutch hydraulic circuit, apply air to the 3rd clutch apply pressure port (refer to Front of Transaxle illustration for proper location). When applying air to 3rd clutch, a small amount of cross leakage between 3rd and 2nd clutch is normal. Second clutch should not immediately apply when applying air to the 3rd clutch apply port, while blocking the 2nd clutch apply port. However, it is normal for 2nd clutch to apply within 2-3 seconds after applying air to the 3rd clutch apply port when the 2nd clutch apply port is blocked. This is due to a small amount of normal leakage around the input shaft feed tube bushing between the 2nd and 3rd clutch.








If 3rd clutch does not apply properly when performing the air check, possible sources of leakage include:

^ Damaged 3rd clutch piston. (1)

IMPORTANT:
To verify that the bushing is at the correct depth refer to the procedure titled "Misplaced or loose input shaft inner tube bushing check procedure" in the Automatic Transaxle Service Manual.

^ Delivery tube bushing in input shaft mislocated or loose. (3)

^ Damaged clutch housing to input shaft 0-ring seal under 3rd clutch. (4)

^ Damaged clutch housing to input shaft 0-ring seal between 3rd and 2nd clutches. (5)

^ Damaged input shaft inner tube 0-ring seal. (6)

^ Damaged or missing delivery tube sleeve. (7)

^ Input shaft inner tube retaining pin out of position. (8)
