only when the transmission has been

removed from the vehicle, or when all

available internal adjustment has been

taken up and a further band adjust-

ment is required.

Internal Band Adjustment

1.
Drain the fluid from the trans-

mission. If the same fluid is to be

used again in the transmission after

the band adjustment, filter the fluid

through a 100-mesh screen as it drains

from the transmission. Re-use the

fluid only if it is in good condition.

2.
Remove and thoroughly clean

the pan and filter. Discard the pan

gasket.

3.
Loosen the rear servo adjusting

screw lock nut.

4.
Pull the adjusting screw end of

the actuating lever away from the

servo body, and insert the spacer tool

shown in Fig. 14 between the servo

accumulator piston and the adjusting

screw.
Be
sure
the
flat
surfaces
of the

tool
are
positioned
squarely
between

the
adjusting
screw
and the
accumula-

tor
piston.
The
tool must
not
touch

piston
and the

must
not
touch

5.
Using a torque wrench with an

Allen head socket (Fig. 14), tighten

the adjusting screw to 24 in-lbs tor-

que.

6. Back off the adjusting screw

1-1/2 turns. Hold the adjusting screw

stationary and tighten the adjusting

screw lock nut sequrely. Remove the

spacer tool.

7.
Install the transmission fluid fil-

ter and clip. Install the pan using a

new gasket.

8. Fill the transmission with fluid.

governor from the counterweight (Fig.

16).

13.
Lubricate the governor valve

parts with clean transmission fluid.

Make certain that
the
valve moves

freely
in the
valve body bore.

14.
Position the governor valve

body on the counterweight with the

cover facing toward the front of the

vehicle. Install and tighten the two at-

taching screws to the specified torque.

15.
Position a new extension hous-

ing gasket on the rear of the transmis-

sion case.

16.
Slide the extension housing into

place and secure it to the transmission

case with the attaching bolts. Torque

the bolts to specification. With the ex-

tension housing installed, rotate
the

output shaft.
The
shaft must rotate

freely
by
hand.
If the

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.

10.
Install but do not tighten, the

control valve body attaching bolts.procarmanuals.com

toward the center of the case until the

clearance is less than 0.050 inch, be-

tween the manual valve and the act-

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.

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.

PARTS REPAIR
AND

REPLACEMENT

During
the
repair
of the sub-

assemblies, certain general instructions

which apply
to all
units
of the
trans-

mission must
be
followed. These
in-

structions
are
given here
to
avoid
un-

necessary repetition.

Handle
all
transmission parts care-

fully
to
avoid nicking
or
burring
the

bearing
or
mating surfaces.

Lubricate
all
internal parts
of the

transmission with transmission fluid

before assembly.
Do
not use any
other

lubricants except
on
gaskets
and

thrust washers which
may be
coated

with vaseline
to
facilitate assembly.

Always install
new
gaskets when
as-

sembling parts
of the
transmission.

Tighten
all

to the

recommended torque.
