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

PARTS REPAIR OR

REPLACEMENT

During the repair of the sub-

assemblies, certain general instructions

which apply to all units of the trans-

missions 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 before assembly with

clean automatic transmission fluid. 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 assembling the transmission.

Tighten all bolts and screws to the

recommended torque as outlined in

the Specification Section.

TRANSMISSION CASE AND

LINKAGE REPAIR

Low-Reverse Servo

1.
Remove the four servo cover-

to-case attaching bolts. Remove the

vent tube and retaining clip from the

case.

2.
Remove the servo cover, cover

seal, servo piston and piston return

spring from the case (Fig. 43).

3.
The servo piston seal is bonded

to the piston. If the seal has to be re-

placed, replace the piston assembly

which includes the seal. Disassemble

the servo piston from the piston stem

by inserting a small screwdriver in the

hole of the piston stem and removing

the piston attaching nut (Fig. 44).

Position the accumulator spring and

spacer (Fig. 43) on the piston stems.

Make sure the crowned side of the

spring is facing toward the rod. Install

the new servo piston and attaching nut

Place the piston return spring in

the servo bore of the case. Lubricate

the piston seal with clean transmission
fluid and install the servo pistion into

the bore of the case.

5.
Place a new cover seal on the

cover and install the servo cover. In-

stall the vent tube and retaining clip.

Install the four cover attaching bolts.

Torque the cover-to-case retaining

Intermediate Servo

1.
Remove the transmission
identif-

ication tag and the four servo cover to

case attaching bolts.

2.
Remove the servo cover, gasket,

servo piston, and piston return spring

3.
Remove the intermediate servo

piston from the cover.

4.
Remove the seal rings from the

servo piston and cover.

5.
Install a new seal on the cover

and servo piston. Figure 46 shows the

correct servo piston and cover for

each transmission model. Lubricate

the seals with clean transmission fluid.

Install the piston into the cover. Be

careful not to damage the piston seal.

6. Install the piston return spring in

the servo bore of the case.

7.
Place a new gasket on the servo

cover. Position the servo piston and

cover assembly into the case with the

piston stem slot in a horizontal posi-

tion to engage the strut. Use two

5/16-18 bolts, 1 1/4 inch long, 180

degrees apart, to position the cover

against the case. Install two cover at-

taching bolts. Remove the two 1 1/4
