The transmission consists essentially

of a torque converter, planetary gear

train, two multiple disc clutches, a
one-way clutch and a hydraulic con-

trol system (Fig. 3).

The only adjustments on the trans-
mission proper are the intermediate

and low-reverse bands.

AND
REPAIRS

CONTROL LINKAGE ADJUSTMENTS

The transmission control linkage

adjustments should be performed in

the order in which they appear in this

section of the manual.

THROTTLE AND DOWNSHIFT

LINKAGE ADJUSTMENTS

Adjusting the throttle linkage is im-

portant to be certain the throttle and

kickdown systems are properly adjust-

ed. The kickdown system should come

in when the accelerator is pressed

through detent, and not before detent.

Refer to Group 10 for detailed

throttle and downshift linkage adjust-

ment procedures.

MANUAL LINKAGE

ADJUSTMENTS

Column Shift

1.
Place the selector lever in the D

position tight against the D stop.

2.
Loosen the shift rod adjusting

nut at point A (Fig. 4 or 5).

3.
Shift the manual lever at the

transmission into the D detent posi-

tion, third from the rear.

4.
Make sure that the selector lever

has not moved from the D stop; then,

tighten the nut at point A to 10-20 ft-

lbs.

5.
Check the transmission operation

for all selector lever detent positions.

Console Shift

1.
Position the transmission selec-

tor lever in D position.

2.
Raise the vehicle and loosen the

manual lever shift rod retaining nut

(Fig. 6, 7 or 8). Move the transmis-

sion manual lever to the D position,

fourth detent position from the back

of the transmission.

3.
With the transmission selector

lever and manual lever in the D posi-

tions,
torque the attaching nut 10 to

20 ft-lbs.

4.
Check the operation of the trans-

mission in each selector lever position.

NEUTRAL START SWITCH

ADJUSTMENT—CONSOLE SHIFT

On vehicles equipped with a

column-mounted neutral start switch,

refer to Part 7-1, Section 2, for the

adjustment procedures.

gagement circuit in all positions. The

circuit must be open in all drive posi-

tions and closed only in park and neu-

tral.

2.
Remove the four screws and

plates securing the selector lever

handle to the lever. Remove the

handle and detent control.

3.
Remove two screws from the

rear of the console top panel. Pull the

panel back to unhook it from the

front of the console and remove the

panel.

4.
Loosen the two combination

starter neutral and back-up light

switch attaching screws (Fig. 9).

5.
Move the selector lever back and
forth until the gauge pin (No. 43 drill)

can be fully inserted into the gauge

pin holes (Fig. 9).

6. Place the transmission selector

lever firmly against the stop of the

neutral detent position.

7.
Slide the combination starter

neutral and back-up light switch for-

ward or rearward as required, until

the switch lever contacts the selector

lever actuator. If an adjustment can

not be made by rotating the switch,

loosen the actuator lever attaching

bolt and adjust the lever (Fig. 9).

8. Tighten the neutral start switch

attaching screws. If the actuator lever

was adjusted, tighten the actuator

lever bolt to 6-10 ft-lbs.procarmanuals.com

MAJOR REPAIR OPERATIONS

Before removing
any of the sub-

assemblies, thoroughly clean
the out-

side
of the
transmission
to
prevent dirt

from entering
the
mechanical parts.

During
the
repair operations, refer
to

Part 7-1
for
common adjustments
and

repairs
or
cleaning
and
inspection
pro-

cedures.

During
the
transmission disassem-

bly
or
assembly operations,
ten
thrust

washers located between
the sub-

assemblies must
be
removed
and in-

stalled.
It is
important that each

thrust washer
be in the
correct posi-

tion during
the
assembly operation.

To properly locate
and
identify
the

thrust washers,
the
various positions

of
the
thrust washers
are
shown
in the

illustrations
and are
numbered
1

through
10. No. 1 is at the
first thrust

washer located
at the
front pump.
The

last thrust washer,
No. 10, is
located

at
the
parking pawl ring gear.
