7. Apply 396 kPa (57 psi) of compressed air into the oil passage to remove the low/reverse brake piston.





8. Remove and discard the low/reverse brake piston 0-rings.

Notice: Check the steel and friction plates for wear or damage. Replace as necessary. New clutch plates should be soaked in Texaco 1854 automatic transmission fluid for two hours before being assembled.





9. Inspect the clutch steel and friction plate surfaces.

Assembly Procedure

Notice: Inspect the transaxle case for damage or wear. Inspect all parts for damage or wear. Check the low/reverse clutch piston and transaxle case seal area for burrs or damage.

1. Clean the components using a clean, high-quality parts cleaning solvent and use compressed air to dry all parts and clean the fluid passages.





2. Install new low/reverse brake piston O-rings.

Notice: Apply Texaco 1854 automatic transmission fluid to the new low/reverse brake piston O-rings and the transaxle seal area. Seat the piston by pushing evenly around the circumference of the piston, being careful not to damage the outer seal.





3. Install the low/reverse brake piston into the case.





4. Install the brake piston return spring and snap ring into the case.
- Compress the brake piston return spring by hand and install the snap ring into the groove with a screwdriver.
- Be sure the end gap of the snap ring is not aligned with one of the case cutouts.





5. Install the front planetary ring gear flange.





6. Install the snap ring.

Notice: Install the flat surface of the thrust washer toward the flange.





7. Install the thrust washer.

Notice: Apply Texaco 1854 automatic transmission fluid to the one-way clutch.





8. Install the one-way clutch.





9. Install the snap ring.

Notice: Apply Texaco 1854 automatic transmission fluid to the one-way clutch inner race.





10. Install the one-way clutch inner race.
11. Verify the operation of the one-way clutch. While holding the front ring gear, verify that the inner race rotates smoothly when turned counterclockwise and locks when turned clockwise.
