FIG. 54—Planetary Clutch, Planet Carrier and Center Support

5.
Carefully position the planet car-

rier on the center support. Move the

carrier forward until the clutch rollers

are felt to contact the bearing surface

of the center support.

6. While applying forward pressure

on the planet carrier, rotate it counte-

rclockwise, as viewed from the rear

(Fig. 55). This will cause the clutch

rollers to roll toward the large open-

ing end of the cams in the race, com-

pressing the spring slightly, so that the

rollers will ride up the chamfer on the

planetary support and onto the inner

race.

7.
Push the planet carrier all the

way forward.

CARRIER
8. Check the operation of the plan-

etary clutch by rotating the carrier co-

unterclockwise. It should rotate count-

erclockwise (viewed from the rear)

with a slight drag, and it should lock

up when attempting to rotate it in a

clockwise direction.

9. Install the selective thrust washer

on the pinion carrier rear pilot. II the

end play was not within specifications

when checked prior to disassembly,

replace the washer with one of proper

thickness. Refer to the Specification

Section of Group 7 for selective thrust

washer thickness.

10.
Install the output shaft, careful-

ly meshing the internal gear with the

pinions.

Installation—Center Support

not Chamfered

1.
Install the center support and the

rear band in the case.

2.
Install the primary sun gear, rear

thrust bearing race, needle bearing

and front thrust bearing race if used

in the planet carrier using petroleum

jelly to retain them in place.

3.
Lubricate the bearing surface of

the center support, the rollers of the

planetary clutch, and the cam race in

the carrier with vaseline.

i. Install the^ planetary clutch on

the center support with the saw teeth

of the clutch cage pointing in the

clockwise direction as viewed from the

rear (Fig. 56). Make sure that all roll-

ers are in the cage.

5.
Position the planet carrier on the

support so that the cams in the carrier

engage the saw teeth on the clutch

cage.

6. Push the planet carrier forward

until the rollers are felt to contact the

surface of the cam race.

7.
While applying forward pressure

on the carrier, rotate it counterclock-

wise as viewed from the rear. This will

cause the rollers to roll toward the

large opening end of the cams in the

race,
compressing the springs slightly,

so that the rollers will enter the cams.

8. Some rollers may become

cocked preventing their entry into the

outer race. These rollers must be posi-

tioned individually with a small screw-

driver by pushing the rear of the roll-

ers toward the transmission and into

the cam race (Fig. 56). Keep pressure

applied to the carrier at all times.

9. After all of the rollers have been

started into the cam race, rotate the

carrier counterclockwise while pushing

it forward. Again, straighten any roll-

ers which still may be in a cocked po-

sition and prevent the carrier from

sliding onto the support.

10.
Make sure that all springs are

entered in the cam race before at-

tempting to push the carrier on the

support. Push the carrier all the way

forward and check the operation of

the clutch by rotating it in a counte-

rclockwise direction. The carrier

should rotate counterclockwise with a

slight drag and should lock up when

attempting to rotate it in a clockwise

direction.

11.
Install the selective thrust wash-

er on the pinion carrier rear pilot. If

the end play was not within specifica-

tions when checked prior to disassem-

bly, replace the washer with one of

proper thickness. Refer to the Specifi-

cation Section of Group 7 for selective

thrust washer thickness.procarmanuals.com

identif-

ication number indicates changes to

service details which affect interchan-

is not changed. For interpretation of

this number, see the Master Parts Ca-

The C6 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 hydrau-

lic control system schematic is shown

in Figure 3. The converter housing

and the fixed splines which engage the

splined OD of the low-reverse clutch

steel plates, are both cast integrally

into the case.

Only one (intermediate) band is

used in the C6 transmission. This

along with the forward clutch is used

to obtain intermediate gear.

The only adjustment on the trans-

mission proper is the intermediate

band.

The fluid is drained from the trans-

mission by loosening the pan bolts

and allowing it to drain. Finally, to

allow the pan to drain more thorough-

ly, remove all bolts except the two

from the front.procarmanuals.com
