On the
bench, install
the for-

ward clutch
in the
reverse-high clutch

by rotating
the
units
to
mesh
the

reverse-high clutch plates with
the

splines
of
the
forward clutch
(Fig. 95).

23.
Using
the end
play check read-

ing that
was
obtained during
the

transmission disassembly
to
determine

which
No.
2
steel backed thrustwasher

is required, proceed
as
follows:

a.
Position
the
stator support verti-

cally
on the
work bench
and
install

the correct
No. 2
thrustwasher
to

bring
the end
play within specifica-

tions.

on the
stator

support.

c. Invert
the
complete unit making

sure that
the
intermediate brake drum

bushing
is
seated
on the
forward

clutch mating surface.

d.
Select
the
thickest fiber washer

(No.
1)
that
can be
inserted between

the stator support
and the
intermedi-

ate brake drum thrust surfaces
and

still maintain
a
slight clearance.
Do

not select
a
washer that must
be

forced between
the
stator support
and

intermediate brake drum.

e. Remove
the
intermediate brake

drum
and
forward clutch unit from

the stator support.

f.
Install
the
selected
Nos.
1 and 2

thrustwashers
on the
front pump
sta-

tor support
(Fig.
28)
using enough

vaseline
to
hold
the
thrust washers
in

position during
the
front pump instal-

lation.

24.
Install thrust washer
No.
3 on

the forward clutch
(Fig. 96).

25.
Install
the
forward clutch
hub

and ring
in the
forward clutch
by ro-

tating
the
units
to
mesh
the
forward

clutch plates with
the
splines
on the

forward clutch
hub (Fig. 97).

26.
Install thrust washer
No.
4 on

the front planet carrier
(Fig. 98).
In-

stall
the
front planet carrier into
the

forward clutch
hub and
ring gear.

Check
the
forward thrust bearing race

inside
the
planet carrier
for
proper

location against
the
thrust bearing.

Make sure
the
race
is
centered
for

alignment with
the sun
gear
on the

input shell
(Fig. 99).

27.
Install
the
input shell
and sun

gear
on
the
gear train
(Fig. 100). Ro-

tate
the
input shell
to
engage
the
drive

lugs
of the
reverse-high clutch.
If the

drive lugs will
not
engage,
the
outer

race inside
the
forward planet carrier

is
not
centered
to
engage
the end of

the
sun
gear inside
the
input shell.

Center
the
thrust bearing race
and
in-

stall
the
input shell.

28.
Hold
the
gear train together

and install
the
forward part
of the

gear train assembly
in the
case
(Fig.

33).

The input shell
sun
gear must mesh

with
the
reverse pinion gears.
The

front planet carrier internal splines

must mesh with
the
splines
on the out-

put shaft.

29.
A
new
band should
be
soaked

in transmission fluid
for
fifteen
min-

utes before
it is
installed. Install
the

intermediate band through
the
front
of

the case
(Fig. 31).

30.
Install
a
new
front pump gasket

on
the
case. Line
up

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).
