^ Gasket and mating surfaces for burrs or nicks
^ Obstructions to vent and fluid passages
^ Cracks or warpage
3. Inspect the extension housing for cracks, burrs or warpage.
4. Inspect the case bearing for damage. If damage to the case bearing is indicated, install a new case.
5. WARNING: Make sure the lock pin on the bench-mounted holding fixture is secure. Failure to follow these instructions may result in personal injury.
Using the special tool, install the transmission into the bench with the converter housing facing up.
6. Using the special tool, install the manual control lever shaft seal and lubricate it with petroleum jelly.
7. Install the parking lever rod.
8. Install the manual control lever.
9. Assemble the manual valve inner lever and parking lever actuating rod as shown.
10. CAUTION: Align the flats on the manual valve inner lever with the flats on the manual control lever shaft.
Install the manual control lever shaft.
11. Install the manual valve inner lever onto the manual shaft and loosely install the nut.
12. CAUTION: Use care not to damage the fluid pan rail surface when installing the retaining pin.
NOTE: Align the manual control lever shaft alignment groove with the manual control lever shaft spring pin bore in the transmission case.
Install the manual control lever shaft spring pin.
^ Tap the manual control lever shaft spring pin into the transmission case.
13. CAUTION: To avoid damage, do not allow the wrench to strike the manual valve inner lever pin.
Tighten the nut.
^ Tighten to 48 Nm (35 ft. lbs.).
14. CAUTION: The tabs on the output shaft thrust washer (No. 11) point into the case. Make sure the thrust washer is correctly seated.
Install the output shaft thrust washer (No. 11).
^ Coat the output shaft thrust washer with petroleum jelly.
15. Install the park gear on the output shaft.
16. Install the output shaft and park gear.
17. Install the low/reverse brake drum.
^ Rotate the low/reverse brake drum clockwise to install.
18. CAUTION: Make sure band is resting on the 2 anchor pins in the case.
Install the low/reverse band over the reverse drum.
19. NOTE: The reverse band actuating lever must fit into the notches in the band.
Install the reverse band actuating lever into the reverse band.
20. Install the reverse band actuating lever shaft into the case and into the reverse band actuating lever.
21. Install the No. 10 needle bearing into the case.
22. CAUTION: Do not damage the seal against the case during assembly.
Install the output shaft ring gear, hub and seal.
23. CAUTION: Always install a new output shaft retaining ring.
Install a new output shaft retaining ring.
24. NOTE: Install the output shaft sleeve with the cone facing up. This sleeve will snap into place when correctly installed.
Install the output shaft sleeve.
25. Install the low/reverse planetary carrier needle bearing (No. 9) onto the output shaft ring gear and hub assembly.
26. CAUTION: Make sure the needle bearings stay in place.
Install the low/reverse planetary assembly.
27. CAUTION: The low/reverse brake drum must be pulled forward to install the low/reverse planet retaining ring.
Install the retaining ring.
28. Install the No. 8 thrust bearing.
29. Install the spacer on the input shell, using petroleum jelly to hold it in place.
30. Install the input shell and sun gear assembly.
31. NOTE: The No. 13 bearing must be correctly seated in the forward planet assembly so the sun gear can be installed correctly.
Install the forward planetary assembly.
32. Install the No. 7 forward planet thrust bearing into the forward ring. gear and hub assembly. Use petroleum jelly to hold the bearing in place.
33. Install the No. 6B forward clutch thrust washer onto the forward ring gear hub.
34. Install the forward ring gear and hub as an assembly.
35. Install the No. 6A forward ring gear hub thrust bearing into the forward ring gear and hub.
36. Install the forward clutch cylinder.
37. Install the No. 5 thrust bearing.
38. Install the intermediate servo piston and spring.
^ Lubricate the servo bore with clean automatic transmission fluid.
39. Using the special tool, install the retaining ring.
40. Install the direct clutch drum.
41. Using a depth micrometer with an 8-inch extension, measure from the top of the gauge bar to the center support ledge in the case at 4 places 90 degrees apart.
^ Add the 4 measurements, divide by 4, and record as dimension A.
42. CAUTION: The torque specifications are critical for this procedure. Failure to use the correct torque specifications may cause transmission damage.
Install the special tool.
1 Install the special tool and the bolts using the 2 pump screw locations at approximately 6 and 12 o'clock positions.
^ Tighten to 15 Nm (11 ft. lbs.).
2 Tighten the center screw.
^ Tighten to 1.13 Nm (10 inch lbs.).
43. NOTE: Align the disc holes on the special tool with the slot in the gauge bar for correct measurement.
Measure the distance from the top of the gauge bar to the drum bearing surface through the hole in the disc, and record as dimension B. Repeat the measurement 180 degrees on the opposite side of the special tool and record as dimension C.
44. Add dimension B to C, divide by 2, and record as dimension D.
45. Subtract A from D and record as dimension E.
46. Select bearing from the following chart, using dimension E.
47. NOTE: Make sure that the intermediate band apply strut is aligned with the band notch.
NOTE: If the intermediate band is reused, it must be installed in the same position as when removed.
NOTE: The new intermediate band is dark in color. This is a normal condition of the band. Hairline cracks in the band are also considered normal. Do not install a new band based solely on the color.
Install the intermediate band.
48. CAUTION: To avoid a "fall-out" condition of the strut from the screw during assembly and function, the small "U" shaped notch should be toward the band/case side and the large "U" shaped notch toward the main control side.
Install the intermediate band anchor strut.
1 Band/case side of the anchor (small U notch).
2 Main control side of the anchor (large U notch).
49. CAUTION: If the strut is installed incorrectly, transmission damage will occur.
