speed shift rail interlock pin with

grease and position it in the shift rail.

26.
Align the third and fourth-

speed shift fork with the shift rail

bores and slide the shift rail into place

making sure that the three detents are

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

valve for proper fluid pressure direc-

tion to the different transmission com-

ponents. Improperly adjusted manual

3.
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).
