(AA) No. 4 clutch (Third speed) (BB) No. 5 clutch (Second speed) (CC) No. 6 clutch (First speed) (DD) No. 1 clutch (Reverse) (EE) No. 3 clutch (Fourth speed) (FF) No. 2 clutch (Forward)
Use Tooling (Q) in order to check the movement of the clutch pistons. Be sure that the clutch pistons move freely by the following steps:
Put air that is free of water under a pressure of 690 to 1030 kPa (100 to 150 psi). Apply the pressurized air to each of the six oil passages.
If the clutch pistons do not move, put a small amount of clean SAE 30 oil into each passage. Check for movement again. If the clutch pistons do not move, then disassemble the transmission. Check the pistons and the seal rings.
