- Position the overdrive/direct clutch assembly in the cover assembly, install the Dial Indicator Gauge with Holding Fixture 100-002 or a suitable dial indicator and position the plunger on the overdrive clutch pressure plate. Apply 483 kPa (70 psi) of air pressure to the overdrive clutch piston port while recording the clutch pack clearance on the Dial Indicator Gauge. The clearance should be between 1.13 mm (0.044 in) and 2.28 mm (0.089 in). If the clearance is out of range, check the overdrive clutch pack for correct installation. If the overdrive clutch pack is correctly installed, install a new overdrive clutch pack.
- Position the Dial Indicator Gauge with Holding Fixture 100-002 on the direct clutch pressure plate. Apply 483 kPa (70 psi) of air pressure to the direct clutch piston port while recording the clutch pack clearance on the Dial Indicator Gauge. The clearance should be between 0.98 mm (0.038 in) and 2.34 mm (0.092 in). If the clearance is out of range, check the direct clutch pack for correct installation. If the direct clutch pack is correctly installed, install a new direct clutch pack.
