9. Rotate the holding fixture until the front of the
transmission is pointing up and remove the seven
oil pump bolts. The bolt holes are offset to facilitate
proper location upon installation.
10. Remove the oil pump and stator shaft assembly and
the selective fit thrust washer using adapter J-9539
and the slide weights from Tool J-6125 (fig. 6PG).
Note the two threaded holes to mount the pullers.
Remove the ring seal and gasket.
NOTE: The pump bolts have special sealing
washers which must be in place upon
installation.
11. Release the tension on the low band adjustment,
then, with transmission horizontal, grasp the
transmission input shaft and carefully work it and
the clutch assembly out of the case (fig. 7PG). Use
care so as not to lose the low sun gear (splined)
bushing from the input shaft. The low sun gear
thrust washer will probably remain in the planet
carrier.
