Reverse and High Clutch Drum Assembly
REVERSE AND HIGH CLUTCH DRUM ASSEMBLYWarning: Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air.
1. Install new seal rings to the high clutch piston.
2. Install new seal rings to the reverse clutch piston.
3. Install the reverse clutch piston and the high clutch piston.
4. Install the return spring.
Caution: If the high clutch cover is not centered, the seal rubber around the circumference of the cover will hit against the return spring and become damaged. Be sure to center the high clutch cover on the return spring.
5. Install the high clutch cover.
6. Install the SSTs as shown in the figure.
Caution: Do not compress the high clutch cover excessively. Doing so can damage the return spring.
7. Compress the high clutch cover using the SST.
8. Install a new snap ring.
9. Remove the SSTs.
10. Apply ATF to the plates of the high clutch.
Caution: If the dished plate is not installed in the specified direction, it may be damaged or not operate properly. Install the plate exactly as shown in the figure.
11. Install the plates and the snap ring to the reverse and high clutch drum in the following order:
Dished-Driven-Drive-Driven-Drive-Driven-Drive-Driven-Drive-Driven-Drive-Driven-Drive-Retaining
12. Apply ATF to the plates of the reverse clutch.
Caution: If the dished plate is not installed in the specified direction, it may be damaged or not operate properly. Install the plate exactly as shown in the figure.
13. Install the plates and the snap ring to the reverse and high clutch drum in the following order:

14. Install the reverse and high clutch drum to the oil pump.
Caution:
^ Applying compressed air to the assembled clutch pack for more than 3 s at a time will damage the seal.
^ Do not apply compressed air for more than the aforementioned time when testing the system.
15. Apply compressed air to the part indicated in the figure and inspect the reverse clutch operation.
^ If there is any malfunction, inspect the seal rings.
Air pressure:
390 kPa (4.0 kgf-cm2, 57 psi) max.
16. Measure the clearance between the retaining plate and the snap ring.
^ If the clearance is not within the specification, adjust the clearance by installing the correct retaining plate.
