  1. Using a dial indicator, measure the direct clutch and overdrive clutch pack clearance while applying and releasing compressed air (392 kPa, 4.0 kgf/cm2, 57 psi).

    Standard pack clearance:
    0.61 to 0.83 mm (0.0240 to 0.0327 in.)
    If the pack clearance is less than the minimum, parts may have been assembled incorrectly, so check and reassemble them again. If the clearance is not as specified, select another flange.
