BUSHING AND REAR SEAL

REPLACEMENT

1.
Disconnect the drive shaft from

the transmission.

2.
Carefully remove the seal with

the tools shown in Fig. 18.

3.
Remove the bushing as shown in

Fig. 19. Use the bushing remover

carefully so that the spline seal is not

damaged.

4.
When installing a new bushing

use the special tool shown in Fig. 20.

5.
Before installing a new seal, in-

spect the sealing surface of the univer-

sal joint yoke for scores. If scores are

found, replace the yoke.

6. Inspect the counterbore of the

housing for burrs. Polish off all burrs

with crocus cloth.

7.

adjusting stud access hole is accessi-

ble.

Remove the access hole plug and,

with Tool 7195-C or Tool T58L-

7195-A, loosen the adjusting stud lock

nut. Turn the adjusting stud in until

the tool handle overruns. This will

tighten the rear band around the plan-

et carrier and will hold the planet car-

rier and clutch assemblies in position

REMOVAL AND INSTALLATION

An oil impregnated plastic grommet

is incorporated in the end of the man-

ual shift linkage lever arm on all col-

umn shift vehicles. A special tool

T67P-7341-A is required to install the

grommet in the manual lever, and to

install the manual linkage rod into the

grommet. Refer to Part 7-1, Section

2,
for the grommet replacement pro-

cedures.

TRANSMISSION AND

CONVERTER REPLACEMENT—

FORD-METEOR

REMOVAL

1.
Drive the vehicle on a hoist, but

do not raise at this time.

2.
Remove the two upper bolts and

lock washers which attach the con-

verter housing to the engine.

3.
Raise the vehicle and remove the

cover from the lower front side of the

converter housing. Drain the fluid

from the transmission.

4.
Remove one of the converter

drain plugs. Then rotate the converter

180 degrees and remove the other

plug. Do not attempt to turn the con-

verter with a wrench on the converter

stud nuts. If desired, the converter

may be drained after the unit has been

removed from the vehicle.

5.
Disconnect the fluid filler tube

from the transmission case. Discon-

nect the vacuum hose from the vacu-

um diaphragm unit and the tube from

the extension housing clip.

6. When the fluid has stopped

draining from the transmission and

converter, remove the flywheel to con-

verter nuts and flat washers. Install

the drain plugs in the converter and

torque to specifications. Install the

converter housing front plate to hold

the converter in place when the trans-

mission is removed.

7.
Disconnect the starter cables

from the starter and remove the start-

er.

8. Disconnect the oil cooler lines

from the transmission. Remove the

transmission vent tube.

9. Disconnect the downshift linkage

from the transmission.

10.
Disconnect the selector rod from

the transmission manual lever with

T67P-7341-A.

11.
Disconnect the speedometer

cable from the extension housing, and

remove the driveshaft.
12.
Support the transmission on a

stand. Remove the engine rear support

to transmission bolts, and raise the

transmission slightly to take the

weight off the cross member. Remove

the cross member. Support the rear

part of the engine.

13.
Remove the remaining convert-

er housing to engine attaching bolts.

Move the assembly to the rear and

down to remove it.

INSTALLATION

1.
If the converter has been re-

moved from the converter housing,

carefully position the converter in the

housing, and then install the housing

lower front cover plate to prevent the

converter from slipping out of the

housing.

2.
Install the transmission vent

tube.
Rotate the converter until the

studs adjacent to the drain plugs are

in a vertical position.

3.
Rotate the flywheel as required

to align the drain plug holes with the

drain plugs in the converter. With the

transmission mounted on a support

stand, move the converter and trans-

mission assembly forward into posi-

tion, using care not to damage the fly-

wheel and the converter pilot.

4.
Install the converter lower

housing-to-engine bolts, then torque

the bolts to specification.

5.
Install the cross member.

6. Lower the transmission until the

extension housing rests on the cross

member, and then install the extension

housing-to-cross member bolts.

7.
The converter must rest squarely

against the flywheel. This indicates

that the converter pilot is not binding

in the engine crankshaft.

8. Install the converter attaching

nuts and flat washers. Install the ac-

cess plates.

9. Connect the oil cooler inlet and

outlet lines to the transmission case.

10.
Coat the front universal joint

yoke seal and spline with B8A-

19589-A lubricant, and install the

drive shaft.

11.
Connect the speedometer cable

at the transmission.

12.
Using tool T67P-7341-A install

a new grommet in the manual lever.

Then secure the manual selector rod

to the lever.

13.
Connect the downshift linkage

and bushing at the transmission

throttle lever.
14.
Install the starter motor.

15.
Connect the fluid filter tube to

the transmission case. Connect the

vacuum hose to the vacuum dia-

phragm unit and the tube to its clip.

16.
Lower the transmission support

stand. Then install the upper two con-

verter housing-to-engine bolts and

tighten them to specification.

17.
Lower the vehicle and fill the

transmission with transmission fluid,

following the recommended procedure.

18.
Check the transmission, con-

verter assembly, and fluid cooler lines

for fluid leaks, and then adjust the

manual and downshift linkages.

TRANSMISSION REPLACEMENT

WITHOUT CONVERTER—

FORD-METEOR

The frame construction of the con-

vertible will not permit the transmis-

sion to be moved rearward enough to

clear the turbine shaft from the con-

verter. For this reason, the converter

and transmission must be removed as

a unit from this model.

REMOVAL

1.
Raise the vehicle on a hoist.

2.
Drain the fluid from the trans-

mission.

3.
Disconnect the hose from the

vacuum diaphragm unit and the tube

from its clip. Disconnect the fluid fill-

er tube from the case.

4.
Remove the cover from the lower

front side of the converter housing.

5.
Remove one of the converter

drain plugs. Then rotate the converter

180 degrees and remove the other

plug. Do not attempt to turn the con-

verter with a wrench on the converter

stud nuts.

6. Disconnect the drive shaft from

the rear axle, and remove the drive

shaft.

7.
Disconnect the fluid cooler lines

from the transmission. Remove the

vent tube.

8. Disconnect the downshift linkage

at the transmission.

9. Disconnect the selector rod from

the transmission manual lever with

tool T67P-7341-A.

10.
Disconnect the speedometer

cable at the extension housing.

11.
Remove the two engine rear

support to transmission bolts.

12.
Position a transmission jack

under the transmission and raise it

slightly to take the weight off the

cross member.procarmanuals.com

PARTS REPAIR
AND

REPLACEMENT

During
the
repair
of the sub-

assemblies, certain general instructions

which apply
to all
units
of the
trans-

mission must
be
followed. These
in-

structions
are
given here
to
avoid
un-

necessary repetition.

Handle
all
transmission parts care-

fully
to
avoid nicking
or
burring
the

bearing
or
mating surfaces.

Lubricate
all
internal parts
of the

transmission with transmission fluid

before assembly.
Do
not use any
other

lubricants except
on
gaskets
and

thrust washers which
may be
coated

with vaseline
to
facilitate assembly.

Always install
new
gaskets when
as-

sembling parts
of the
transmission.

Tighten
all
bolts
and
screws
to the

recommended torque.

FRONT PUMP

1.
Remove the stator support at-

taching screws and remove the stator

support. Mark the top surface of the

pump driven gear with Prussian blue

to assure correct assembly. Do not

scratch the pump gears.

2.
Remove the drive and driven

gears from the pump body.

3.
Refer to Fig. 39 for a disas-

sembled view of the front pump. In-

spect the pump body housing, gear

pockets and crescent for scores.

4.
If the pump housing bushing is

to be replaced, press the bushing from

the front housing with the tools shown

in Fig. 40.

5.
Press a new bushing into the

pump housing with the handle and

tool shown in Fig. 40.

6. If any parts other than the stator

support or bushings are found defec-

tive,
replace the pump as a unit.

Minor burrs and scores may be re-

moved with crocus cloth. The stator

support is serviced separately.

7.
Bolt the front pump to the trans-
