6. Install the compressing tool

shown in Fig. 29 and compress the

springs just enough to install the low-

reverse clutch piston retainer snap

ring.

7.
Install the snap ring, then re-

move the compressing tool.

8. Place the transmission case on

the bench with the front end facing

downward.

9. Position the parking gear thrust

washer and the gear on the case (Fig.

33).
Do not restake the thrust washer.

10.
Position the oil distributor and

tubes in place on the rear of the case.

Install and torque the attaching bolts

to specification.

11.
Install the output shaft, and

governor as an assembly.

12.
Place a new gasket on the rear

of the transmission case. Position the

extension housing on the case and in-

stall the attaching bolts. Torque the

attaching bolts to specification.

13.
Place the case in the holding

fixture.

14.
Align the low-reverse clutch hub

and one-way clutch with the inner

race at the rear of the case. Rotate

the low-reverse clutch hub clockwise

while applying pressure to seat it on

the inner race.

15.
Install the low-reverse clutch

plates,
starting with a steel plate and

following with friction and steel plates

alternately. Retain them with vaseline.

Refer to the Specifications Section for

the number of plates required. If new

composition plates are being used,

soak them in clean transmission fluid

for fifteen minutes before installation.

Install the pressure plate and the snap

ring. Test the operation of the low-

reverse clutch by applying air pressure

at the clutch pressure apply hole in

the case.

16.
Install the reverse planet ring

gear thrust washer and the ring gear

and hub assembly. Insert the snap

ring in the groove in the output shaft.

17.
Assemble the front and rear

thrust washers onto the reverse planet

assembly; retain with vasoline. Insert

the assembly into the ring gear and

install the snap ring.

18.
Set the reverse-high clutch on

the bench, with the front end facing

down. Install the thrust washer on the

rear end of the reverse-high clutch as-

sembly. Retain the thrust washer with

vaseline and insert the splined end of

forward clutch into the open end of

the reverse-high clutch so that the

splines engage the direct clutch fric-

tion plates (Fig. 43).

19.
