23. Place the forward planet assembly into the forward hub and ring gear assembly.





24. NOTE: The thrust bearing notched inner race must face outward and the large outer diameter radius must face inward.

Verify the No. 9B forward clutch thrust bearing is installed.





25. Align the notches with the lugs and position the input shell onto the intermediate brake drum. Rotate the input shell until fully seated.





26. NOTE: When installing the special tool. each leg of the tool must be rotated separately to engage notches on the input shell, prior to tightening the top cross bar.

Using the special tool, lower the direct clutch, forward clutch and input shell as an assembly into the case.





27. Install the intermediate band with the ear resting on the anchor pin.





28. NOTE: Prior to installation, lightly lubricate the piston seal with clean automatic transmission fluid.

Gently press the intermediate band servo assembly piston into the case bore.





29. NOTE: Clock position is viewed looking into the converter housing with the top of the transmission in the 12 o'clock position.

30. NOTE: The following stack-up check measurement indicates not only the amount of space existing between the center support assembly and the intermediate brake drum, it also will indicate if the unit has been correctly built to this point.

Measure the stack up.
1 Hold the thrust washer against the center support assembly.
2 Extend the probe of the special tool into the hole until flush with the No. 6 center support thrust washer surface.
3 Record this as reading 1.





31. CAUTION: Do not misalign the center support in the case bore. This can cause case bore damage.
