47. Rotate case to horizontal position, valve body side
facing up.

Remove spring pin (55), using cutting pliers, then
remove parking lock and selector lever assembly
(56).NOTE: Insert wire in the center of the spring pin to
prevent it from collapsing during removal. Be aware of pin
height. Protect machined face of main case.
48. Remove parking lock and range selector lever 17 mm
nut (57).
49. Remove parking lock and range selector lever (56),
and actuator assembly.
50. Remove selector shaft (58).
NOTE: Inspect the shaft for burrs before removing to
prevent damaging seal. If necessary, remove burrs by
lightly sanding with an oilstone.

Reassembly
1. Inspect selector shaft seal, and replace it if
necessary.
NOTE: Use a seal installer when replacing the seal.

Install selector shaft.
NOTE: Spring pin groove must be positioned inside the
case.
2. Install spring pin. Be sure the selector shaft can move
freely. Do not push the pin flush with the case surface.
Leave enough height for removal.
3. Install actuator assembly (1).
4. Install parking lock and range selector lever (2) and
new 17 mm nut. Tighten the nut to the specified
torque.
Torque: 22 Nwm (16 lb ft)

5. Rotate main case to vertical position, extension end
facing down.

Install brake band assembly (3).
NOTE: Be sure to align servo pin area with the servo hole.
6. Install thrust bearing (4).
NOTE: The case bushing acts as a guide for the thrust
bearing.
7. Install brake drum (5).
8. Install reaction sun gear (6).
9. Install needle bearing (7).
10. Inspect planetary carrier assembly (8) for wear and
damage. If necessary replace it.

Measure pinion end play clearance with a feeler
gauge.
Clearance: 0.13mm±0.89mm (0.005 in±0.035 in)
If clearance is outside specified value, replace the
planetary carrier assembly.

11. Install the thrust bearing (9) on the output shaft.
NOTE: Use petroleum jelly to hold the thrust bearing in
place.
12. Align planetary pinions. Each pinion is marked with
double points to indicate the master tooth space and
exactly opposite with a single point to indicate the
master tooth. The markings on the planetary carrier
consist of double lines which are to be lined up with
the double points on two opposite pinions; the single
lines are to be lined up with the single points on the
other two pinions.

After all four pinions are lined up, slide on the third
clutch assembly. Rotate third clutch and check
mark alignment. Considering that the ring gear
tooth between the double points of one planetary
pinion is tooth number 1, count the teeth to check
that the single points on the two adjacent pinions
are between teeth 23 and 24 of the ring gear, and
that the ring gear tooth between the double points of
the opposite pinion is tooth number 46. If the ring
gear and pinions are not lined up, remove, and
realign them.
13. Install planetary carrier (8) with third clutch (12).
NOTE: Do not force. When properly aligned, the parts will
fit together easily.
