Overhaul (Assembly Steps 1-24)
CAUTION: Before beginning assembly, carry out and inspect the following:
When building up subassemblies and assembling the transmission, ALWAYS use new gaskets and seals.
All fasteners must be tightened to the torque specification indicated.
When building up subassemblies, each component part should be lubricated with clean transmission fluid. It is also good practice to lubricate the subassemblies as they are installed in the case.
Needle bearings, thrust washers and seals should be lightly coated with petroleum jelly during subassembly buildup or transmission assembly.
Many components and surfaces in the transmission are precision machined. Careful handling during disassembly, cleaning, inspection and assembly can prevent unnecessary damage to machined surfaces.
1. Use the special tools to install the rear case bushing if removed.
1 Position the rear case bushing and the special tool inside the case.
2 Assemble the special tools through the back of the case.
2. Place the transmission in the vertical position.
3. Coat the No. 9 case rear bearing with petroleum jelly and install on the case boss.
4. CAUTION: Be sure the No. 7 needle bearing and direct clutch hub are installed as shown in the Subassembly section. Internal damage and shift problems may occur.
Install the output shaft and output shaft ring gear.
5. Install the No. 8 bearing.
6. Install the direct clutch.
7. NOTE: The reverse band support retaining ring is used for assembly purposes during production. The reverse band support retaining ring is not required during assembly and it will not affect the operation of the transmission.
Install the reverse band support retaining ring.
8. NOTE: Make sure the band is seated on the anchor pins.
Install the reverse band.
9. NOTE: The planetary assembly and planetary gear support cannot be installed unless the notch cut in the planetary gear support is aligned with the overdrive band anchor pin.
NOTE: The top of the planetary gear support must be below the snap ring groove.
Install the planetary assembly and planetary gear support as a unit.
^ Rotate the output shaft to fully seat the planetary assembly.
10. NOTE: The planet support spring must be compressed and installed below the snap ring groove. When the planet support spring is installed correctly both ends of the spring will be visible.
Install the case to the planet support spring located at the 1 o'clock position.
11. NOTE: When installing the center support retaining ring the opening of the center support retaining ring should be toward the hole in the case where the turbine shaft speed (TSS) sensor would go.
Install the center support retaining ring.
12. Install the forward clutch sun gear, the No. 5 forward clutch sun gear 2 piece bearing and the reverse sun gear.
13. Install the No. 4 forward clutch hub bearing.
14. Install the intermediate stub shaft.
15. Install the forward clutch hub and the No. 3 forward clutch hub front bearing.
16. Install the forward clutch assembly.
17. NOTE: Make sure the reverse clutch cylinder lugs are completely seated in the notches of the reverse sun gear.
Install the reverse clutch cylinder assembly.
1 Install the reverse clutch cylinder.
2 Install the No. 2 forward clutch bearing.
18. Install the overdrive band. Position the overdrive band pocket onto the anchor pin.
19. Install the overdrive servo spring.
1 Install the overdrive servo piston return spring.
2 Install the overdrive servo piston.
20. Verify the tip of the piston assembly engages the pocket of the overdrive band.
21. Using the special tool, compress the overdrive servo assembly and install the overdrive servo retaining ring.
22. Install the intermediate clutch pressure plate.
23. NOTE: Before assembly, soak the new clutch discs in clean automatic transmission fluid.
Install the intermediate clutch pack and selective steel plate.

Selective Steel Plates (Part 2):
24. Using the special tool, check the intermediate clutch clearance.
1 Position the special tool on the pump case mounting surface.
2 Maintaining downward pressure, use a depth micrometer to measure and verify intermediate clutch clearance is within specification.
If the intermediate clutch is not within specification, install a correct selective plate.
