CENTERING CHECK

1.
Install a 0-2000 psi pressure

gauge Tool T56L-33610-D in the pres-

sure line between the power steering

pump outlet port and the integral

steering gear inlet port.

2.
Make sure that the valve on the

gauge is in the fully open position.

3.
Check the fluid level in the reser-

voir and fill it to proper level with the

specified fluid.

4.
Start the engine and cycle the

steering wheel from stop-to-stop, to

bring the steering lubricant up to nor-

mal operating temperature. Stop the
engine and recheck the reservoir. Add

fluid if necessary.

5.
With the engine running at ap-

proximately 1000 rpm and the steer-

ing wheel centered, attach an inch-

pound torque wrench to the steering

wheel retaining nut. Apply sufficient

torque to the torque wrench in each

direction, either side of center, to get

a gauge reading of 250 psi.

6. The torque reading should be the

same in both directions when 250 psi

is reached. If the difference between

the readings exceeds 4 in-lbs, the

steering gear must be removed and the

valve centering shim removed from the

valve housing and a thicker or thinner
shim installed. Only one shim is to be

used. If the steering effort is heavy,

the shim thickness should be in-

creased. Shim thickness should be de-

creased if the steering effort is light to

the left.

The out of vehicle procedure for

valve centering check is the same as

for the in vehicle except the torque

and simultaneous pressure reading

must be made at the right and left

stops instead of either side of center.

taching bolts to the proper torque. If

necessary, replace the gasket.

Check the fluid filler tube connec-

tion at the transmission case or pan.

If leakage is found here, install a new

O-ring or tighten the fitting to the

specified torque.

Check the fluid lines and fittings

between the transmission and the

cooler in the radiator tank for loose-

ness,
wear, or damage. If leakage can-

not be stopped by tightening a fitting,

replace the damaged parts.

Check the engine coolant in the ra-

diator. If transmission fluid is present

in the coolant, the cooler in the radia-

tor is probably leaking.

The cooler can be further checked

for leaks by disconnecting the lines

from the cooler fittings and applying

50-75 psi air pressure to the fittings.

Remove the radiator cap to relieve the

pressure build at the exterior of the oil

cooler tank. If the cooler is leaking

and will not hold this pressure the

cooler must be replaced. Cooler re-

placement is described in the Cooling

System Section of Group 11.

If leakage is found at either the

downshift control lever shaft or the

manual lever shaft, replace either or

both seals.

Inspect the pipe plug on the left

side of the transmission case at the

front. If the plug shows leakage, tor-

que the plug to specifications. If tight-

ening does not stop the leaks, replace

the plug. On a C6 transmission, a TV

pressure plug is also provided on the

right rear side of the case.

When converter drain plugs leak,

remove drain plugs with a six-point

wrench. Coat the threads with FoMo-

Co Perfect Seal Sealing Compound or

its equivalent, and install the plugs.

Torque the drain plugs to specifica-

tion. Fluid leakage from the converter

housing may be caused by engine oil

leaking past the rear main bearing or

from oil gallery plugs, or power steer-

ing oil leakage from steering system.

Be sure to determine the exact cause

of the leak before repair procedures

are started.

Oil-soluble aniline or fluorescent dyes

premixed at the rate of 1/2 teaspoon

of dye powder to 1/2 pint of transmis-

sion fluid have proved helpful in locat-

ing the source of the fluid leakage.

Such dyes may be used to determine

whether an engine oil or transmission

fluid leak is present or if the fluid in

the oil cooler leaks into the engine

coolant system. A black light, how-

ever, must be used with the fluorescent

dye solution.

CONVERTER LEAKAGE

CHECK

If there are indications that the

welds on the torque converter are

leaking, the converter will have to be

removed and the following check

made before the unit is replaced.

A leak checking tool (Fig. 2) can be

made from standard parts. The tool

can be used to check all converters.

1.
Install the plug in the converter

(Fig. 3) and expand it by tightening

the wing nut. Attach the safety chains.

2.
Install the air valve in one of the

drain plug holes.

3.
Introduce air pressure into the

converter. Check the pressure with a

tire gauge and adjust it to 20 psi.

4.
Place the converter in a tank of

water. Observe the weld areas for

bubbles. If no bubbles are observed, it

may be assumed that the welds are

not leaking.

ENGINE IDLE SPEED CHECK

Check and, if necessary, adjust the

engine idle speed, using the procedure

given in Group 10.

If the idle speed is too low, the en-

gine will run roughly. An idle speed

that is too high will cause the vehicle

to creep, have harsh engagements and

harsh closed-throttle downshifts.
ANTI-STALL DASHPOT

CLEARANCE CHECK

After the engine idle speed has been

properly adjusted, check the anti-stall

dashpot clearance. Follow the proce-

dure given in Group 10 for checking

and adjusting this clearance.

MANUAL LINKAGE CHECKS

Correct manual linkage adjustment

is necessary to position the manual

Install the bench testing tool on

the transmission.

4.
Remove the
1/8-inch
pipe plug

at the transmission case. Turn the

front pump in a clockwise direction at

75-100 rpm until a regular flow of

transmission fluid leaves the hole in

the transmission case. This operation
bleeds the air from the pump.

5.
Install the pressure gauge (77820

or T57L-77820-A) as shown in Fig.

13.

PRESSURE TESTS

Turn the front pump at 75-100 rpm
and note the gauge readings. The

pressure readings on the bench test

must be within the limits as outlined

in Figure 13, for the engine idle check.

If pressure gauge readings are with-

in limits in all selector lever positions,

install the vacuum diaphragm control

rod unit.

COMMON ADJUSTMENTS AND REPAIRS

TRANSMISSION FLUID DRAIN

AND REFILL

Normal maintenance and lubrica-

tion requirements do not necessitate

periodic automatic transmission fluid

changes.

If a major repair, such as a clutch

band, bearing, etc., is required in the

transmission, it will have to be re-

moved for service. At this time the

converter, transmission cooler and

cooler lines must be thoroughly

flushed to remove any dirt.

When filling a dry transmission and

converter, install five quarts of fluid.

Start the engine, shift the selector

lever as outlined below, and check and

add fluid as necessary.

Following are the procedures for

partial drain and refill due to in-

vehicle repair operation.

C4 TRANSMISSION

1.
On PEA models, disconnect the

fluid filler tube from the transmission

oil pan to drain the fluid.

On PEB and PEE models, loosen

the pan attaching bolts to drain the

fluid from the transmission.

2.
When the fluid has stopped

draining from the transmission, re-

move and thoroughly clean the pan

and the screen. Discard the pan gas-

ket.

3.
Place a new gasket on the pan,

and install the pan on the transmis-

sion.

4.
On PEA models, connect the

filler tube to the pan and tighten the

fitting securely.

5.
Add three quarts of fluid to the

transmission through the filler tube.

6. Run the engine at idle speed for

about two minutes, and then run it at

fast idle speed (about 1200 rpm) until

it reaches it's normal operating temp-

erature. Do not race the engine.

7.
Shift the selector lever through

all the positions, place it at P, and

check the fluid level. The fluid level

should be above the ADD mark. If
necessary, add enough fluid io the

transmission to bring the level be-

tween the ADD and FULL marks on

che dipstick. Do not overfill the trans-

mission.

FMX OK C6

TRANSMISSION

1.
Raise the vehicle on a hoist or

jack stands.

2.
Place a drain pan under the

transmission.

3.
Loosen the pan attaching bolts

to drain the fluid from the transmis-

sion.

4.
After the fluid has drained to the

level of the pan flange, remove the

rest of the pan bolts working from the

rear and both sides of the pan to

allow it to drop and drain slowly.

5.
When the fluid has stopped

draining from the transmission, re-

move and thoroughly clean the pan

and the screen. Discard the pan gas-

ket.

6. Place a new gasket on the pan,

and install the pan on the transmis-

sion.

7.
Add three quarts of fluid to the

transmission through the filler tube.

8. Run the engine at idle speed for

about two minutes, and then run it at

fast idle speed (about 1200 rpm) until

it reaches normal operating tempera-

ture.
Do not race the engine.

9. Shift the selector lever through

all the positions, place it at P, and

check the fluid level. The fluid level

should be above the ADD mark. If

necessary, add enough fluid to the

transmission to bring the level be-

tween the ADD and FULL marks on

the dipstick. Do not overfill the trans-

mission.

OIL COOLER TUBE

REMOVAL AND INSTALLATION

When fluid leakage is found at the

oil cooler, the cooler must be re-

placed. Cooler replacement is de-

scribed in the Cooling System Section

of Group 11.
When one or more of the fluid

cooler steel tubes must be replaced,

each replacement tube must be fabri-

cated from the same size steel tubing

as the original line.

Using the old tube as a guide, bend

the new tube as required. Add the

necessary fittings, and install the tube.

After the fittings have been tight-

ened, add fluid as needed, and check

for fluid leaks.

VACUUM DIAPHRAGM

ADJUSTMENT NON-ALTITUDE

COMPENSATING TYPE

The C4 and C6 transmissions are

equipped with an adjustable vacuum

diaphragm assembly. A similar ad-

justable diaphragm has been released

for service with the FMX transmis-

sion. However, the FMX service dia-

phragm is not interchangeable with

that used on C4 and C6 models.

The vacuum diaphragm assembly

has an adjusting screw in the vacuum

hose connecting tube (Fig. 14).

FIG. 14—Adjustable Vacuum Unit

The inner end of the screw bears

All readings slightly high or all

readings slightly low may indicate the

vacuum unit needs adjustment to cor-

rect a particular shift condition.procarmanuals.com

07-01-09

General Transmission Service

07-01-09

For example, on a C4 transmission,

if the pressure at 10 inches of vacuum

was 120 psi and the pressure at 1.0

inch of vacuum was 170 psi, and up-

shifts and downshifts were harsh, a di-

aphragm adjustment to reduce the di-

aphragm assembly spring force would

be required.

If the pressure readings are low, an

adjustment to increase diaphragm

spring force is required.

To increase control pressure, turn

the adjusting screw in clockwise to re-

duce control pressure, back the adjust-

ing screw out by turning it counte-

rclockwise. One complete turn of the

adjusting screw (360 degrees) will

change idle line control pressure ap-

proximately 2-3 psi. After the adjust-

ment is made, install the vacuum line

and make all the pressure checks as

outlined in the Specification Section.

The diaphragm should not be ad-

justed to provide pressure below the

ranges shown in the Specification Sec-

tion in order to change shift feel. To

do so could result in soft or slipping

shift points and damage to the trans-

mission.

ALTITUDE

COMPENSATING TYPE

The altitude—compensating di-

aphragm is provided with an adjust-

ment screw located in the vacuum

connecting tube (Fig. 15). The adjus-

table feature allows control and TV

pressures to be adjusted (within limits)

to correct soft or harsh shift feel.

Control and TV pressures are in-

creased or decreased by turning the

adjusting screw.

Before replacing or adjusting the di-

aphragm, it must first be determined

that the pressure or vacuum is actual-

ly out of specification and that the

cause of the problem is not due to

other items within the transmission or

vacuum connecting lines.

If the tests outlined in the Specifi-
cation Section have been performed

and pressures are within specification

but shift feel is unsatisfactory, or if

the pressure is too high or too low at

10 inches of vacuum, the vacuum di-

aphragm may be adjusted to improve

the shift feel.

If shifts are excessively harsh, the

diaphragm should be adjusted to re-

duce control pressure by backing off

the adjusting screw (counterclock-

wise).
If shift quality is extremely soft,

control pressure should be increased

by turning the adjusting screw inward

(clockwise).

To adjust the vacuum diaphragm to

compensate for harsh shift quality,

first check control pressure in D, 2

and 1 at 10 inches manifold vacuum

and note the pressure reading ob-

tained. Remove the T-fitting from the

vacuum hose and back off the adjust-

ing screw (counterclockwise) by one

full turn. Each full turn will reduce

control pressure by approximately 2

1/2 psi at 10 inches of vacuum. Test

the vehicle for shift feel. If shift quali-

ty is still harsh, a further adjustment

should be made to reduce control

pressure. However, control pressure

should not be reduced below the speci-

fication shown for 10 inches of vacu-

um. If control pressure has been re-

duced to the low limit and shift feel is

still excessively harsh, the clutches and

band should be checked for correct

operation.

To adjust the vacuum diaphragm to

compensate for extremely soft shifts,

record the control pressure reading at

10 inches of vacuum in D, 2 and 1,

then make an initial adjustment of

one full turn inward (clockwise). Test

the vehicle for shift feel and again ad-

just the diaphragm, if necessary. Con-

trol pressure at 10 inches of vacuum

must not exceed the high limit shown

in the Specification Section.

When the necessary adjustments

have been completed and shift feel is

satisfactory, repeat all the tests out-

NEUTRAL START SWITCH

ADJUSTMENT AND

REPLACEMENT—COLUMN SHIFT

There are two types of column-

mounted neutral start switches: A and

B.
Type A switch has a parking brake

brake-release vacuum valve. Type B

switches do not have a vacuum valve.

The switches differ in appearance but

not in operation. Both switches are

actuated by a removable steel lever,

which is installed in the shifter tube

within the steering column assembly.

The following procedures outline the

steps necessary to correctly adjust and

replace the neutral start switch.

SWITCH ADJUSTMENT

Neutral Position

1.
With the selector lever held light-

ly against the neutral stop, attempt to

start the engine. If the engine starts

while holding the lever but does not

start when the lever is released, the

shift linkage should be adjusted. If the

engine does not start in either condi-

tion, adjust the switch.

2.
To adjust the switch in neutral,

place the transmission selector lever

against the stop of the neutral detent

position.

3.
Loosen the two retaining screws

that locate the switch on the steering

column (Fig. 16).

4.
With the selector lever against

the neutral stop, rotate the switch

until a start in the neutral position is

obtained. Then, tighten the switch at-

taching screws to 20 in-lbs torque.

5.
With the switch properly adjust-

ed in neutral, place the selector lever

in the 1 position and push the park

reset button (Fig. 16) to the left

(counterclockwise) until it stops. The

park reset must be performed when-

ever the switch has been adjusted.

Park Position

1.
Place the selector lever in the

park position, release the lever and at-

tempt to start. If the engine does not

start, reset the park adjustment.procarmanuals.com

2.
To adjust the switch for the park

position, place the transmission selec-

tor lever in 1 and push the park reset

button (Fig. 16) to the left (counter-

clockwise) until it stops.

3.
Check the operation of the

switch in each selector lever position.

The starter should engage in only the

neutral and park positions. Be sure to

perform
the
park reset
if for any rea-

son
the
neutral switch
is
adjusted.

If,
after performing
the
switch
ad-

justments,
the
starter still will
not en-

gage
in the
neutral
or
park positions,

replace
the
switch. Never replace
the

neutral switch until
the
switch adjust-

ments have been made.

SWITCH REPLACEMENT

1.
Disconnect the neutral start

switch wires at the plug connector.

2.
Disconnect the vacuum hoses, if

so equipped.

3.
Remove the two screws securing

the neutral start switch to the steering

column and lift the switch from the

column.

Check the column to be sure the

metal switch actuator is secure to the

shift tube and that it is seated as far

forward against the shift tube bearing

as is possible. Also check for a broken

or damaged actuator. If it is broken

or damaged, replace it as shown in

Figure 17.

4.
Before installing a new switch to

the column, check to see that the red

neutral position gauge inserted in the

neutral pinning hole. If the pin is

missing, align the two holes at the

neutral pinning hole on top of the

switch and install a No. 43 drill or

0.092-0.093 inch gauge pin.
