22. Lubricate the second oil seal ring (614) with transmission fluid, and position the ring on the J 34741-1 seal protector .
23. Using the J 34741-2 seal pusher , quickly slide the oil seal ring (614) into the oil seal ring groove.



24. Size the oil seal rings with the J 34741-3 seal sizer .
25. Leave the J 34741-3 seal sizer in place for at least five minutes.
26. Remove the J 34741-3 seal sizer .



27. Lubricate the 3rd clutch piston seals with a light coating of J 36850 assembly lubricant or equivalent.
28. Install the 3rd clutch piston assembly (606) into the bottom side of the 3rd clutch housing (604). Use a twisting motion when pushing the piston into the housing.
29. Install the spring and retainer assembly (607), and install the snap ring retainer (608).



30. Install the J 39694 clutch compressor -1 and the J 39694 clutch compressor -3 and compress the spring and retainer assembly.
31. Install the snap ring (609).
32. Remove the J 39694 clutch compressor -1 and the J 39694 clutch compressor -3.



33. Install the following parts:

•	The apply plate (611)

•	The four fiber clutch plates (610)

•	The three steel clutch plates (612)

Note: The backing plate (613) must be installed with the stepped side up.

34. Install the backing plate (613).
35. Install the snap ring (515).



36. Install the following parts:

•	The thrust washer (615)

•	The third clutch hub and bushing assembly (617)

Note: Make sure that the rolled inner lip of the thrust bearing (619) is facing toward the clutch pack.

•	The thrust bearing (619).

37. Install the reaction sun gear and shell assembly (620). If the thrust bearing (619) was removed, install this bearing inside the reaction carrier assembly (623).
38. Install the reaction carrier assembly (623).

Note: Make sure that the thrust bearing (640) is installed with the black surface toward the clutch pack.
