Look at the bearing spacer located on the output shaft. You will notice a flat with two half-moon shaped slots 180° apart. Measure the distance
from the case flange (1) to this surface (2). Be sure not to make your measurement in the slot. This is Dimension A.
^
Look into the extension housing. Notice the snap ring installed around the outside of the inner diameter (4). Dimension B is from the top
surface of this snap ring to the case flange (3).
^
Subtracting Dimension B from Dimension A gives Dimension C. With Dimension C known, you will determine which selective spacer to
install in the transmission. See the table at the end of this procedure.

Place the selected selective spacer in place over the output shaft and into position.
Important:
The used ball bearing assembly removed from the extension housing previously will be TEMPORARILY installed into the new extension
housing assembly to allow for the critical end play measurement. This ball bearing assembly must be replaced with the new ball bearing
assembly after the end play has been determined to be within the allowable range.
34.
TEMPORARILY reinstall the original ball bearing using the Rear Bearing Installer Tool J 24446.
35.
Reinstall the retaining ring, beveled side up.

Rotate the transmission so that the converter housing is facing up.
