Special Tools Required

- Clutch spring compressor set 07LAE-PX40000

NOTE: Hold the spring compressor set in a vise with soft jaws. Be careful not to damage the clutch drum.

1. Soak the clutch discs thoroughly in ATF for at least 30 minutes.

2. Install a new O-ring (A) in the 1st clutch piston (B), and install a new O-ring (C) on the clutch drum (D).






3. Install the clutch piston (A) in the clutch drum (B). Apply pressure and rotate to ensure proper seating. Lubricate the piston O-ring with ATF before installing. Do not pinch the O-ring by installing the piston with too much force.






4. Set the return spring (A) and the spring retainer (B) on the clutch piston, and position the snap ring (C) on the spring retainer.






5. Install the clutch spring compressor set.






6. Set the clutch spring compressor set (A) on the spring retainer (B) so that it compresses the clutch return spring (C).
NOTE: Coat the circumference of the spring retainer and the areas where the spring retainer contacts the clutch piston with ATF before installation.






7. Compress the return spring carefully until the snap ring can be installed. Check that the spring retainer (A) is properly installed on the clutch hub (B). If improperly installed, change the position of the spring compressor attachment and the spring retainer.
NOTE: Insert the spring retainer so it can be adjusted (center of tolerance) to prevent damaging the spring retainer oil seal.






8. Install the snap ring using snap ring pliers.

9. Remove the clutch spring compressor set.






10. Make sure the oil seal of the spring retainer (A) is properly installed on the clutch piston (B). If the oil seal was damaged or cracked, replace the spring retainer.






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






12. Install the snap ring using a screwdriver to secure the clutch end-plate.

13. Check that the clutch piston moves by applying air pressure into fluid passage.
