9. Remove bearing race from oil pump assembly.





10. Remove needle bearing from front sun gear.





11. Remove front sun gear assembly from front carrier assembly.

NOTE:
Remove front sun gear by rotating it left and right.





12. Remove seal rings from input clutch assembly.





13. Remove front carrier assembly (with input clutch assembly and rear internal gear) from rear carrier assembly.

CAUTION:
Do not remove it with needle bearing.





14. Loosen lock nut and remove band servo anchor end pin from transmission case.





15. Remove brake band from transmission case.

CAUTION:





- To prevent brake linings from cracking or peeling, do not stretch the flexible band unnecessarily. When removing the brake band, always secure it with a clip as shown.
- Check brake band facing for damage, cracks, wear or burns.

17. Remove mid carrier assembly from rear carrier assembly.





18. Remove needle bearing (front side) from mid carrier assembly.





19. Remove needle bearing (rear side) from mid carrier assembly.





20. Remove bearing race from rear carrier assembly.





21. Remove needle bearing from rear carrier assembly.





22. Remove mid sun gear assembly, rear sun gear assembly and high and low reverse clutch hub as a unit.

CAUTION:
Remove them with bearing race and needle bearing.





23. Remove high and low reverse clutch assembly from direct clutch assembly.

CAUTION:
Make sure that needle bearing is installed to the high and low reverse clutch assembly edge surface.





24. Remove needle bearing from drum support.





25. Remove direct clutch assembly from reverse brake.





26. Remove snap ring from A/T assembly harness connector.





27. Push A/T assembly harness connector.

29. Check foreign materials in oil pan to help determine causes of malfunction. If the A/T fluid is very dark, smells burned, or contains foreign particles, the frictional material (clutches, band) may need replacement. A tacky film that will not wipe clean indicates varnish build up. Varnish can cause valves, servo, and clutches to stick and can inhibit pump pressure.
- If frictional material is detected, perform A/T fluid cooler cleaning. Procedures.





30. Remove magnets from oil pan.
