Typical Example
Apply 690 to 1030 kPa (100 to 150 psi) of shop air pressure into each oil passage (138) (total of six).If the clutch pistons do not move, apply a small amount of clean transmission oil in each oil passage and check for movement again. If the clutch pistons do not move, the transmission must be disassembled again so that the clutch pistons and the seal rings can be checked.Note: The mounting surfaces for the transmission modulating valves must be clean. Clean the surfaces before installation of the transmission modulating valves.
