PRESSURE REGULATOR

(FMX TRANSMISSION)

1.
Inspect the regulator body and

cover mating surface for burrs.

2.
Check all fluid passages for ob-

structions.

3.
Inspect the control pressure and

converter pressure valves and bores for

burrs and scores. Remove all burrs

carefully with crocus cloth.

4.
Check free movement of the

valves in their bores. The valves

should fall freely into the bores when

both the valve and bore are dry.

5.
Inspect the valve springs and

spacers for distortion.

CONTROL VALVE BODY

1.
Clean all parts thoroughly in

clean solvent, and then blow them dry

with moisture-free compressed air.

2.
Inspect all valve and plug bores

for scores. Check all fluid passages for

obstructions. Inspect the check valve

for free movement. Inspect all mating

surfaces for burrs or distortion. In-

spect all plugs and valves for burrs

and scores. Crocus cloth can be used

to polish valves and plugs if care is

taken to avoid rounding the sharp

edges of the valves and plugs.

3.
Inspect all springs for distortion.

Check all valves and plugs for free

movement in their respective bores.

Valves and plugs, when dry, must fall

from their own weight in their respec-

tive bores.

4.
Roll the manual valve on a flat

surface to check it for a bent condi-

tion.

GOVERNOR

1.
Inspect the governor valves and

bores for scores. Minor scores may be
removed from the valves with crocus

cloth. Replace the governor if the

valves or body is deeply scored.

2.
Check for free movement of the

valves in the bores. The valves should

slide freely of their own weight in the

bores when dry. Inspect fluid passages

in the valve body and counterweight

for obstructions. All fluid passages

must be clean.

3.
Inspect the mating surfaces of

the governor body and governor dis-

tributor (C4 or C6 Automatic) for

burrs and distortion. Mating surfaces

must be smooth and flat.

4.
Check the mating surface of the

governor valve and the counterweight

on a FMX transmission for burrs or

scratches.

5.
When cleaning the governor as-

sembly (C4 Automatic), the oil screen

should be removed from the collector

body and thoroughly blown out with

compressed air.

FRONT SERVO (FMX)

AND INTERMEDIATE

SERVO (C4 AND C6

AUTOMATIC)

1.
Inspect the servo bore for cracks

and the piston bore and the servo pis-

ton stem for scores. Check fluid pas-

sages for obstructions. Replace seals

that are damaged.

2.
On an FMX transmission, check

the actuating lever for free movement,

and inspect it for wear. If necessary to

replace the actuating lever or shaft,

remove the retaining pin and push the

shaft out of the bracket.

Inspect the adjusting screw threads

and the threads in the lever for dam-

age.

3.
Check the servo spring and servo

band strut(s) for distortion.

4.
Inspect the cover seal and gasket

cover sealing surface for defects.
REAR SERVO (FMX)

AND LOW-REVERSE SERVO

(C4 TRANSMISSION)

1.
Inspect the servo body for cracks

and the piston bore for scores.

2.
Check the fluid passages for ob-

structions.

3.
Inspect the band and the struts

for distortion. Inspect the band ends

for cracks.

4.
Inspect the servo spring for dis-

tortion.

5.
Inspect the band lining for exces-

sive wear and bonding to the metal

band.

6. On an FMX transmission, check

the servo body to case mating surface

for burrs. Check the accumulator pis-

ton and the check valve for freedom

of movement. Check the actuating

lever socket for scores.

7.
Replace seals that are damaged.

CASE

Inspect the case for cracks and

stripped threads. Inspect the gasket

surfaces and mating surfaces for

burrs.
Check the vent for obstructions,

and check all fluid passages for ob-

structions and leakage (Figs. 10, 11

and 12).

Inspect the case bushing for scores.

Check all parking linkage parts for

wear or damage.

ONE-WAY CLUTCH

1.
Inspect the outer and inner races

for scores or damaged surface area

where the rollers contact the races. If

the outer race on the C6 transmission

is damaged, the low-reverse clutch hub

must be replaced.

2.
Inspect the rollers and springs

for excessive wear or damage.

3.
Inspect the spring and roller case

for bent or damaged spring retainers.procarmanuals.com

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

for
fifteen
min-

utes before
it is
installed. Install
the

intermediate band through
the
front
of

the case
(Fig. 31).
