NOTE: Refer to figure for order of their removal.
16. Remove coupler from solenoid valve (1).
17. Remove oil strainer (1).
18. Remove valve body (2) mounting bolts as shown in the figure.
19. Lift valve body (1) and disconnect A/T throttle cable (3) from throttle cam (2). And remove valve body (1).
20. Disconnect throttle cable (3) from case (4).
21. Remove accumulator pistons (1) by blowing air into holes as shown in the figure.
NOTE: Hold accumulator piston (1)with shop cloth while blowing.
22. Place transmission upright as shown in the figure.
NOTE:
^ To prevent transmission case from getting damaged, protect its contacting surface with stand by using shop cloth or the like.
^ A stand of such size as shown in the figure will facilitate work.
23. Check top surface level of forward clutch (2) against case (1) for reassembly.
24. Remove forward clutch.
NOTE: Confirm direction of bearing and bearing race for reassembly.
25. Remove direct clutch (1).
26. Remove parking rod (1) and parking pawl (2).
27. Remove 2 bolts (1) from valve body side to remove center support.
28. Remove center support assembly (1).
29. Remove retaining ring (1), planetary gear assembly and leaf spring.
NOTE:
^ Use care not to cause damage to case when removing retaining ring.
^ Confirm direction of bearing and bearing race for reassembly.
30. Remove reverse brake retainer (1).

(B): 09926-98320
31. Remove brake applying cover (1).
32. Remove rear action sleeve and reverse brake piston by blowing air into hole (1) with (2) hole closed.
33. Undo caulking of sleeve cover (1) by using moderate stick (2) and move sleeve cover (1).
34. Using a punch, drive out manual shift lever pin, pull out manual shift shaft (2) and remove manual shift lever (1) Then remove sleeve cover from manual shift lever (1).
35. Remove oil seal (1) from both sides of transmission case.
Reassembly
1. Apply A/T fluid to forward input shaft O-rings, install forward clutch piston and piston return spring (2) to forward input shaft and then install return spring ring with special tool and hydraulic press.
Special tool
(A): 09926-98310
NOTE:
^ When installing return spring (2), be careful so that return spring will not fall or tilt.
^ Do not align opening in retaining ring (1) with lug of forward clutch piston return spring at its retainer section.
CAUTION: Be careful when applying pressure, for overpressure will cause plate section of piston return spring to deform.
2. Install clutch discs from the thinnest one to thicker ones to piston side and then install retaining clutch ring.
NOTE:
^ Refer to "Forward Clutch Components:" when installing each component.
^ Do not match opening in retaining clutch ring and dent in forward clutch input shaft.
3. Install bearing races and thrust bearing.
4. Install forward clutch hub (3), direct clutch input hub (2) and retaining back plate ring (1) in that order.
