5.
Install Tool J-5824 to support the clutch assembly

during removal.

NOTE: Look for "X" mark on flywheel and on

clutch cover. If MX" mark is not evident, prick

punch marks on flywheel and clutch cover for

indexing purposes during installation.

6. Loosen the clutch-to-flywheel attaching bolts evenly

1 turn at a time until spring pressure is released,

then remove the bolts, and remove clutch assembly.

Installation to Vehicle

Clean pressure plate and flywheel face. (They should

be free of oil, grease, metal deposits or burned spots).

1.
Position the clutch disc and pressure plate in relar

tive installed position and support them with align-

ment Tool J-5824.

NOTE: The driven disc on the 4 and 6 cylinder

engines is installed with the damfper springs to

the flywheel side; the V-8 is opposite, however,

THE GREASE SLINGER IS ALWAYS ON THE

TRANSMISSION SIDE.

2.
Turn clutch assembly until "X" mark on cover lines

up with "X" mark oh flywheel, then align cover bolt

holes to nearest flywheel holes.

3.
Install a bolt in every hole and tighten down evenly

and gradually until tight (to avoid possible clutch

distortion).

NOTE: Cover loads are as high as 1-1/4 tons.

4.
Remove pilot tool.

5.
Unhook clutch fork and lubricate ball socket and fork

fingers at release bearing end with a high melting

point grease such as graphite and reinstall fork on

ball stud. On Corvette models use Moly Grease.

6. Lubricate the recess on the inside of throwout bear-

ing collar and the throwout fork groove with a light

coat of graphite grease (fig. 4). On Corvette models

use Moly Grease.

7.
Install clutch fork and dust boot into clutch housing

and install throwout bearing to the throwout fork, then

install flywheel housing.

8. Install transmission as outlined in transmission

section.

9. Connect fork push rod and spring.

10.
Adjust shift linkage as outlined in transmission

section.

11.
Perform linkage adjustment for pedal free play and

check clutch release position.

CLUTCH PEDAL

The clutch pedal is the pendant-type hung from a sup-
Fig. 5 - Release Bearing Lubrication and Comparison

port brace common to the brake pedal and must be re-

moved to remove brake pedal. Refer to Section 5 for

brake and clutch pedal service procedure.

CLUTCH CROSS SHAFT (Figs. 6, 7 & 8)

Removal

1.
Remove linkage return and lower linkage springs and

disconnect clutch pedal and fork push rods from re-

spective cross shaft levers.

2.
Loosen outboard ball stud nut and slide stud out of

bracket slot.

3.
Move cross shaft outboard, and as required to clear

inboard ball stud, then merely lift out to remove

from vehicle.

Repairs

The cross shaft has nylon ball stud seats which should

be inspected for wear or damage. Also check condition

of engine bracket ball stud assembly and special anti-

rattle "O" ring. Figures 6, .7
&
8 show component parts

of cross shaft. Replace parts as necessary based on wear

or damage. Lubricate ball studs and seats with graphite

grease before reassembly.

Installation

1.
Reverse removal procedure to install.

2.
Adjust clutch linkage as previously outlined.

Replacement

In the event replacement is necessary use the following

procedure.

1.
Remove seat separator (console) assembly.

2.
Remove shift lever seal retainer and slide seal up

on lever.

3.
Remove shift lever knob, and the 2 lever to bracket

retaining nuts and remove the lever assembly.

4.
Replace blocker cable - thread new cable up through

lever and MT" handle and install cable retainer

through access slot. Adjust retainer to hold blocker

end .010/.020" above lever bracket surface, then lock

and cut off excess cable.

5.
Reverse Steps 1, 2 and 3 to install.
Figure 3M shows the adjustment and lubrication proce-

dure for the mechanism. This Figure applies to both

models of lever assemblies.

NOTE: If, for any reason, the cable assembly

is removed from the handle, it is difficult to in-

stall without rework. This is due to the fact that

the extra length of the cable is trimmed after

assembly and, therefore, it is almost impossible

to get the shortened cable to enter the cable hole

in the cylindrical retainer.

If new service cable assemblies are not available, the

original part can be re-used by butt soldering a 2.00 inch

piece of small wire to the cable end. Trim the solder

joint so that it will pass through the hole in the retainer.

After assembly, trim off the excess wire as shown in

Figure 3M.

Adjustment

1.
With set screw loose, assemble cable through hole

in cylindrical retainer above handle.

GENERAL DESCRIPTION

The case
and
converter housing
of the two
speed alumi-

num Powerglide Transmission
is a
single case aluminum

unit. When
the
manual control
is
placed
in the
drive
po-

sition,
the
transmission automatically shifts
to low
gear

for initial vehicle movement.
As the car
gains speed
and

depending
on
load
and
throttle position,
an
automatic shift

is made
to
high gear.
A
forced downshift feature
pro-

vides
a
passing gear
by
returning
the
transmission
to low

range.

The
oil
pump assembly
is a
conventional gear type
and

the
oil
pump housing
is of the
large diameter type acting

as
the
front bulkhead
of the
transmission.
The
torque

converter
is a
conventional three element welded design

bolted
to the
engine flywheel which drives through
a
two-

speed planetary gearset.
The
high clutch assembly
is

typical
of the
designs used
in
this type transmission.
The

aluminum Powerglide uses
an
output shaft mounted
gov-
ernor which requires
a
hole through
the
output shaft.
The

reverse clutch assembly
is a
multiple disc type clutch.

The steel plates
are
splined directly
to the
case while
the

face plates
are
splined
to the
internal
or
ring gear.
The

clutch piston operates within
the
rear portion
of the
case.

The internal diameter
of the
pistoh
is
sealed to
an
integral

hub portion
of the
case rear bulkhead.
The
outside
dia-

meter
is
sealed
to a
machined portion
of the
case.
The

piston
is
hydraulically applied
and is
released
by
separate

coil springs.
The
valve body assembly
is
bolted
to the

bottom
of the
transmission case
and is
accessible
for

service
by
removing
the oil pan
assembly.
The
valve

body consists
of an
upper
and
lower body located
on
either

side
of a
transfer plate.
The
vacuum modulator
is lo-

cated
on the
left rear face
of the
transmission case.
The

modulator valve bore
is
located
in the
upper valve body.

MAINTENANCE
AND
ADJUSTMENTS

OIL LEVEL CHECK

The transmission
oil
level should
be
checked period-

ically
as
recommended
in
Section
0. Oil
should
be
added

only when level
is on or
below
the
"ADD" mark
on the dip

stick with
oil hot or at
operating temperature.
The oil

level
dip
stick
is
located
at the
right rear
of the
engine
compartment. Fill with
oil
specified
in
Section
0.

In order
to
check
oil
level accurately,
the
engine should

be idled with
the
transmission
oil hot and the
control

lever
in
neutral (N) position.

It
is
important that
the oil
level
be
maintained
no

higher than
the
"FULL" mark
on the
transmission
oil

level gauge.
DO NOT
OVERFILL,
for
when
the oil
level
