shaft do not move freely, loosen the bolts on the
ATF pump body, and remove the accumulator cover
and accumulator body.
8. Realign the ATF pump driven gear shaft, reinstall
the accumulator body and the accumulator cover,
then retighten the bolts on the ATF pump body to
the specified torque. Recheck the ATF drive gear
and the ATF driven gear shaft movement.

gear shaft correctly will result in seized ATF pump
gears or a seized ATF pump driven gear shaft.
9. Install the regulator separator plate and two dowel
pins on the ATF pump body.
10. Install the Stator shaft with a new O-ring and stop
shaft.
11. Install the regulator valve body (eight 6 mm bolts
and one 8 mm bolt).
12. Install the ATF feed pipes on the accumulator body.
13. Install the park rod assembly with the detent lever
on the control shaft, and install the detent spring on
the transmission housing, if necessary (see page
).
14. Assemble the mainshaft sub-assembly (see page
).
15. Assemble the countershaft sub-assembly (see page
).
16. Install the secondary driven gear shaft in the torque
converter housing.
3. Loosely install the ATF pump body with two 8 mm
bolts and three 6 mm bolts. Make sure the ATF
pump drive gear rotates smoothly in the normal
