TRANSMISSION AND OVERDRIVE
REMOVAL
1. Remove drain plugs and drain lubricant.
2. Remove the nuts, washers and clamps from the rear
axle companion flange and drop the propeller shaft
and withdraw propeller shaft with sleeve yoke
assembly from transmission.
NOTE: Use a rubber band or tape to hold bearing
cups and needle rollers in place.
3. Disconnect the low and reverse and the high and
intermediate shift rods at the transmission shifter
levers.
4. Disconnect the speedometer cable at transmission
and the governor wire at the overdrive control
switch.
5. Disconnect the overdrive control cable from the
overdrive shift shaft lever.
6. Remove the two screws attaching the clutch cross
shaft support assembly to the bottom of the trans-
mission case and remove the support.
7. Remove the governor and governor driven gear
and the speedometer driven gear.
8. Using a universal socket on a 10" extension, re-
move the top bolts attaching the transmission case
to clutch housing. Install two J-2969 Guide Studs
to support transmission when removing the two
lower bolts.
9. Remove the transmission and overdrive assembly,
using care not to damage the main drive gear
splines and pilot during removal.
DISASSEMBLY
1. In stall transmission in a bench holding
fixture and if transmission has not been
drained at removal, do so before disassembly.
2. Remove the transmission cover and gasket.
3. Remove the two screws and washers and remove
the overdrive control switch and gasket.
4. Use a pin punch and drive out the overdrive
control shaft tapered pin, Figure 1. Pull the
control shaft outward approximately 3/8" to
disengage the operating
cam of the shift shaft from the slot in the rail.
5. Remove three screws and washers and remove the
output shaft rear bearing retainer and gasket.
6. Remove the mainshaft bearing snap ring and spacer.
7. Remove the four bolts, 5/8" socket, attaching the
overdrive housing to the transmission, and over-
drive adapter.
8. Slide the overdrive housing rearward carefully.
Lightly tap the end of the overdrive mainshaft with
a soft hammer to prevent the mainshaft from com-
ing off with the overdrive housing and spilling the
free wheeling rollers.
NOTE: After removing the overdrive housing in-
stall one of the bolts removed from the housing to
hold the adapter plate to the transmission case
.
9. Remove the speedometer gear and governor gear
from the output shaft. (Do not lose the Woodruff
Key).
10. Remove the overdrive mainshaft and ring gear
assembly, Figure 4, (Catch the rollers as they drop
out of the free wheeling cam roller retainer.)
11. Removing the retaining clip at the end of the clutch
cam, Figure 6, will allow removal of the cam and
pinion cage assembly.
12. Remove the "U" clip located between the free
wheeling cam and pinion cage and separate these
units. Figure 7.
13. Remove the sun gear and shift rail assembly, Fig-
ure 8.
14. Remove the solenoid by turning the solenoid one-
quarter turn clockwise, Figure 9.
15. Remove the large snap ring at the adapter
plate, Figure 10, and remove the retainer plate,
the sun gear, control plate and blocker assem-
bly and solenoid pawl, Figure 11.
NOTE: With a small pointed brush, paint a fine
line across the synchronizer rings, sleeve and the
second and high gears to facilitate proper assembly
of these parts in reassembly, Figure 4, Page 85.
16. Remove the one bolt previously used to hold the
adapter to the case and using a soft hammer, tap the
front side of the adapter plate to release the adapter
plate from the transmission case and then pull the
