25. Install sun gear to front carrier thrust bearing race assembly with roller thrust bearing against front sun gear, see image. This thrust bearing requires only one thrust race.





26. Install front carrier and thrust bearing assembly, see image.

27. Install front internal gear and thrust washer.

28. Install rear selective thrust washer with identification number toward front of transmission.

29. Install snap ring on output shaft making sure it is fully seated in output shaft groove.





30. Install output shaft to turbine shaft front selective thrust washer in output shaft and retain with petrolatum, see image.








31. Install intermediate band, locating band ply lug and anchor pin in case slots, see images.








32. Install direct and forward clutch assemblies and rotate into place, see first image. When properly installed, the direct clutch housing will be about 15/16 inches (33-34 mm) from pump face in case, see second image.

33. Install 2 oil pump to transmission case alignment pins in case. Before installing pump, make sure intermediate band anchor pin plug is aligned with band anchor pin hole in case.

34. Install oil pump assembly. Install all except one retaining bolt and finger tighten. If turbine shaft cannot be rotated as oil pump is being drawn into place, the forward or direct clutch housings have not been properly installed to index with all the clutch plates. This condition must be corrected before pump is pulled into place.

35. Replace alignment pins with two bolts and torque pump to case bolts to 15-20 ft lbs (20-27 Nm). Make sure turbine shaft rotates freely.

51. Insert 2 valve body to case retaining screws through valve body, gaskets and spacer plate, then install these parts, aligning manual valve with detent lever pin, see image above step 47. Make sure check balls, 1-2 accumulator piston and manual valve do not fall out.

52. Install but do not tighten all valve body retaining bolts except throttle lever bracket assembly and oil screen bolts. The oil screen bolts are about 3/8 inch (10 mm) longer than the valve body bolts an are not interchangeable.

53. Remove guide pins and install inside detent roller and spring assembly, locating tang in valve body and roller on inside detent lever. Install retaining bolts.

59. Install oil screen and gasket and torque retaining bolts to 9-12 ft lbs (13-17 Nm).

60. Install speedometer gear into housing and install assembly into transmission case.

61. Install retainer and bolt, aligning slot in gear housing with retainer. Torque bolt to 6-10 ft lbs (8-14 Nm).
