specifications after the transmission is

assembled, either the wrong selective

thrust washers were used, or a thrust

washer came out of position during

the transmission assembly operation.

1.
Install thrust washer No. 9 inside

the transmission case (Fig. 87).

2.
Place the one-way clutch outer

race inside the case. From the back of

the case install the six outer race-

to-case attaching bolts. Torque the

bolts to specification with the tools

shown in Fig. 88.

3.
Place the transmission case in a

vertical position with the back face of

the case upward. Install the parking

pawl retaining pin in the case (Fig.

89).

4.
Install the parking pawl on the

case retaining pin. Install the parking

pawl return spring as shown in Fig.

89.

5.
Install thrust washer No. 10 on

the parking gear (Fig. 90). Place the

gear and thrust washer on the back

face of the case (Fig. 89).

6. Place the two distributor tubes in

the governor distributor sleeve. Install

the distributor sleeve on the case. As

the distributor sleeve is installed, the

tubes have to be inserted in the two

holes in the case and the parking pawl

retaining pin has to be inserted in the

alignment hole in the distributor

sleeve.

7.
Install the four governor distrib-

utor sleeve-to-case attaching bolts and

torque the bolts to specification.
8. Install the governor distributor

assembly on the output shaft. Install

the distributor retaining snap ring

(Fig. 40). Figure 91 shows the correct

snap ring to be used.

9. Check the rings in the governor

distributor, making sure the rings are

fully inserted in the ring grooves and

will rotate freely. Install the output

shaft and governor distributor assem-

bly in the distributor sleeve (Fig. 39).

10.
Place a new extension housing

gasket on the case. Install the exten-

sion housing, vacuum tube clip, and

the extension housing-to-case attach-

ing bolts. Torque the bolts to specifi-

cation.

11.
Place the transmission in the

holding fixture with the front pump

mounting face of the case up. Make

sure thrust washer No. 9 is still lo-

cated at the bottom of the transmis-

sion (Fig. 86).

12.
Install the one-wa> clutch

spring retainer into the oui:er race

(Fig. 92).

13.

transmission case, install the one-way

clutch rollers by slightly compressing

each spring and positioning the roller

between the spring and the spring re-

tainer.

16.
After the one-way clutch has

been assembled, rotate the inner race

clockwise to center the rollers and

springs. Install the low and reverse

drum (Fig. 86). The splines of the

drum have to engage with the splines

of the one-way clutch inner race.

Check the one-way clutch operation

by rotating the low and reverse drum.

The drum should rotate clockwise but

should not rotate counterclockwise.

17.
Install thrust washer No. 8 on

top of the low and reverse drum (Fig.

93).
