Soak the clutch discs thoroughly in ATF for a minimum of 30 minutes.

Install the new O-ring (A) on the clutch piston (B), and install the O-ring (C) on the clutch drum (D).

Coat the piston O-ring with ATF, and install the clutch piston (A) in the clutch drum (B) while applying pressure and rotating to ensure proper seating. Do not pinch the O-ring.

Install the return spring (A), and install the spring retainer (B) can be adjusted (center of tolerance) to prevent damaging the retainer oil seal.

Position the snap ring (C) on the spring retainer.

Install the clutch spring compressor attachments and the clutch spring compressor bolt assembly.

Set the clutch spring compressor attachment (A) on the spring retainer (B), and over the clutch return spring end, so the clutch spring compressor attachment works on the clutch return spring (C).

If either end of the clutch spring compressor attachment is not set over the clutch return spring end, reset the clutch spring compressor attachment over the return spring end.

Coat between the mating areas of the spring retainer oil seal and the clutch piston with ATF. Compress the return spring (A) carefully until the snap ring (B) can be installed, and install the spring retainer (C) to ensure proper seating in the clutch piston, and over the clutch hub (D). Do not pinch the spring retainer oil seal.

Install the snap ring with the snap ring pliers.

Remove the clutch spring compressor attachments and the clutch spring compressor bolt assembly.

Check that the spring retainer oil seal (A) is properly seated in the clutch piston (B).

If improperly seated, remove the spring retainer, and check the oil seal. If the oil seal is worn, damaged, or peeling, replace the spring retainer, and reinstall the new retainer in the clutch piston.

Install the wave spring (A) in the 1st clutch drum (B). Starting with the clutch wave-plate, alternately install the wave-plates (C) (6) and discs (D) (6). Install the clutch end-plate (E) with the flat side down on the top disc.
