^ Check the fluid passages for obstructions. All fluid passages must be clean and free of obstructions.
^ Inspect the clutch plates for damage
^ Inspect the clutch springs.
Items 9 and 10: Direct and Overdrive Piston Outer and Inner Seal Ring Assembly Note
1. CAUTION: The lip seals must be positioned as shown. Care must be taken to prevent rollover of the lip seal.
NOTE: Use new seals to help prevent seal failures.
Lubricate the seals, then install the new direct clutch piston inner seal and the direct clutch piston outer seal
2. CAUTION: Care must be taken to prevent damage to the seals during installation.

Items 4 and 3: Direct Clutch Internal/External Splined Friction Plate Assembly Note
1. CAUTION: The direct clutch friction plates are directional and must be installed correctly. Alternate the internally splined (clockwise) and the externally splined (counterclockwise) clutch plates. If new plates are used, they should be soaked in clean automatic transmission fluid for at least 30 minutes before assembly.
When installing friction plates, alternate the internally splined (clockwise) and the externally splined (counterclockwise) clutch plates. Install the direct clutch disc pack.
2. Install the friction plates. Alternate the internally splined (clockwise) and the externally splined (counterclockwise) clutch plates starting with an externally splined (counterclockwise) clutch plate.
Item 1: Retaining Ring Assembly Note
1. WARNING: Air pressure must not exceed 138 kPa (20 psi). Wear safety glasses when using compressed air, and make sure drum is facing down as shown. Failure to follow these instructions may result in personal injury.
Air check the assembly.
^ Apply air pressure to the hole in the drum while blocking the other hole with a finger.
2. Push down on direct clutch disc pack and check gap between the direct clutch retaining ring and the direct clutch pressure plate with a feeler gauge.
^ If specifications do not match, use a select fit direct clutch retaining ring to match specifications and verify with a feeler gauge.
