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.

Thread Repair-Case

Thread service kits may be pur-

chased from local jobbers or the

Heli-Coil Corporation. To repair a

damaged thread, the following proce-

dures should be carefully followed.

1.
Drill out the damaged threads,

using the same drill size as the thread

01).
For example, use a 5/16-inch

drill for a 5/16-18 thread.

2.
Select the proper special tap and

tap the drilled hole. The tap is marked

for the size of the thread being re-

paired. Thus, the special tap marked

5/16-18 will not cut the same thread

as a standard 5/16-18 tap. It does cut

a thread large enough to accommo-

date the insert, and after the insert is

installed the original thread size

(5/16-18) is restored.

3.
Select the proper coil inserting

tool. These tools are marked with the

thread size being repaired. Place the

insert on the tool and adjust the sleeve

to the length of the insert being used.

Press the insert against the face of

the tapped hole. Turn the tool clock-

wise and wind the insert into the hole

until the insert is 1/2 turn below the

face.

4.
Working through the insert, bend

the insert tang straight up and down

until it breaks off at the notch.

5.
If the inserts are not properly in-

stalled, they can be removed with the

extractor tool. Place the extractor tool

in the insert so that the blade rests

against the top coil 1/4 to 1/2 turn

away from the end of the coil. Tap

the tool sharply with a hammer so

that the blade cuts into the insert.

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).

DESCRIPTION

DESCRIPTION

Figure 1 shows the location of the

converter, front pump, clutches,

bands,
gear train and most of the in-

ternal parts used in the FMX Trans-

mission

The identification tag (Fig. 2) on an

FMX transmission is attached under

the oil pan by a pan to case bolt. The

tag includes the model prefix and suf-
fix, assembly part number and the

build date code.

The service identification number

indicates changes to service details

which affect interchangeability when

the transmission model is not

changed. For interpretation of this

number, see the Master Parts Catal-

og-

The tag must be kept with the indi-

vidual transmission it was originally
installed on. If the tag was removed

during disassembly, reinstall it on the

same unit.

The FMX transmission is a three

speed unit capable of providing auto-

matic upshifts and downshifts through

the three forward gear ratios, and also

capable of providing manual selection

of first and second gears.

The transmission consists essentially

of a torque converter, planetary gear

train, two multiple disc clutches and a

hydraulic control system (Fig. 3).

tion.
3.

the
diaphragm unit. Remove

the push rod. Remove the fluid screen

retaining clip and the screen.
