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.

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

service details which affect interchan-

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
D1925-A
and allowing it to drain. Finally, to
allow the pan to drain more thorough-
ly, remove all bolts except the two

the case and at the same time, press
the input shaft inward until it bottoms
(Fig. 24). Set the dial indicator to
read zero.
6. Pry the gear train forward (Fig.
24) and note the amount of gear train
end play on the dial indicator. Record
the end play to facilitate assembling
the transmission. Remove the dial in-
dicator from the pump and the tool
from the extension housing.
7.
Remove the vacuum diaphragm,
rod and the primary throttle valve
