ASSEMBLY OF

TRANSMISSION

When assembling the transmission

sub-assemblies (Fig. 86), make sure

that the correct thrust washer is used

between certain sub-assemblies. Lubri-

cate remaining surfaces with transmis-

sion fluid. Vaseline should be used to

hold the thrust washers in their proper

location. If the end play is not within

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.
Install the inner race inside of

the spring retainer.

14.
Install the individual springs be-

tween the inner and outer race as

shown in Fig. 92.

15.
Starting at the back of the

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).
Install the low-reverse band in the

case,
with the end of the band for the

small strut toward the low-reverse

servo (Fig. 38).

18.
Install the reverse ring gear and

hub on the output shaft.

19.
Move the output shaft forward

and install the reverse ring gear hub-

to-output shaft retaining ring (Fig. 37).

37).

20.
Place thrust washers Nos. 6 and

7 on the reverse planet carrier (Fig.

94).

21.
Install the planet carrier in the

reverse ring gear and engage the tabs

of the carrier with the slots in the

low-reverse drum.procarmanuals.com

OIL
PAN AND
CONTROL

VALVE BODY REPLACEMENT

1. Raise the vehicle so that the

transmission fluid pan is accessible.

2.
Drain the fluid from the trans-

mission by loosening the pan attach-

ing bolts starting at the rear of the

pan and working toward the front.

When most of the fluid has drained

from the pan, remove the remainder

of the attaching bolts. Remove the

pan and gasket. Discard the gasket. If

the same fluid is to be used again in

the transmission, filter the fluid

through a 100-mesh screen before in-

stalling it in the transmission. Re-use

the fluid only if it is in good condi-

tion.
3.
Disconnect the hose from the

vacuum diaphragm unit. Remove the

diaphragm unit using tool FCO-24.

Do
not use any
tools
on the dia-

phragm housing, such
as
pliers, pipe

wrenches,
etc. Do not
allow solvents

to enter
the
diaphragm unit. Remove

the push rod. Remove the fluid screen

retaining clip and the screen.

4.
Remove the fluid filter retaining

clip and the filter.

5.
Remove the two tubes which

connect to the pressure regulator and

the control valve body (Fig. 17).

6. Loosen the front servo attaching

bolts three turns.

7.
Remove the three control valve

body attaching bolts, and lower the

valve body while pulling it off the

front servo tubes. Be carefull not to

damage
the
valve body
or the
tubes.

8.
Before installing the control

valve body, check for a bent manual

valve by rolling it on a flat surface.

9. Install the control valve body by

aligning the front servo tubes with the

holes in the valve body. Shift the man-

ual lever to the 1 detent, and place the

inner downshift lever between the

downshift lever stop and the downshift

valve.
The
manual valve must engage

the actuating
pin in the
manual detent

lever.

toward the center of the case until the

clearance is less than 0.050 inch, be-

tween the manual valve and the act-

uating pin on the manual detent lever.

specification. Be sure that the rear

fluid filter retaining clip is installed

under the valve body bolt as shown in

Figure 17.

13.
Install the tubes to the pressure

regulator and the control valve body.

14.
Turn the manual valve one full

turn in each manual lever detent posi-

tion. If the manual valve binds against

the actuating pin in any detent posi-

tion, loosen the valve body attaching

bolts and move the body away from

the center of the case. Move the valve

body only enough to relieve the bind-

ing. Torque the attaching bolts and

recheck the manual valve for binding.

15.
Position the push rod in the

bore of the vacuum diaphragm unit.

Using the diaphragm unit as a guide,

insert the push rod into the threaded

opening of the case. Torque the dia-

phragm unit to specification. Connect

the vacuum hose.

16.
Torque the front servo attach-

ing bolts to specification.

17.
Adjust the front band. If the

unit is a model PHB-C, D, E, F, G or

H, adjust the rear band at this time.

18.
Install the fluid filter and the

filter retaining clip.

19.
Position a new fluid pan gasket

on the bottom of the transmission

case,
and install the pan. Torque the

pan screws to specification.

20.
Adjust the rear band on

PHB-A and PHD models.

21.
Fill the transmission with fluid.

If
the
fluid that
was
drained from
the

transmission
is to be
used
again,
filter

the fluid through
a
100-mesh screen
as

it
is
poured back into
the
transmis-

sion.
Re-use
the
fluid only
if it is in

good
condition.

22.
If the control valve body was

replaced, adjust the transmission con-

trol linkage.
