1. Raise the vehicle so that the

transmission fluid pan is accessible.

2.
Drain the fluid from the trans-

mission by loosening the pan attach-

ing bolts starting at the rear of the

pan and working toward the front.

When most of the fluid has drained

from the pan, remove the remainder

of the attaching bolts. Remove the

pan and gasket. Discard the gasket. If

the same fluid is to be used again in

the transmission, filter the fluid

through a 100-mesh screen before in-

stalling it in the transmission. Re-use

the fluid only if it is in good condi-

tion.
3.
Disconnect the hose from the

vacuum diaphragm unit. Remove the

diaphragm unit using tool FCO-24.

Do
not use any
tools
on the dia-

phragm housing, such
as
pliers, pipe

wrenches,
etc. Do not
allow solvents

to enter
the
diaphragm unit. Remove

the push rod. Remove the fluid screen

retaining clip and the screen.

4.
Remove the fluid filter retaining

clip and the filter.

5.
Remove the two tubes which

connect to the pressure regulator and

the control valve body (Fig. 17).

6. Loosen the front servo attaching

bolts three turns.

7.
Remove the three control valve

body attaching bolts, and lower the

valve body while pulling it off the

front servo tubes. Be carefull not to

damage
the
valve body
or the
tubes.

8.
Before installing the control

valve body, check for a bent manual

valve by rolling it on a flat surface.

9. Install the control valve body by

aligning the front servo tubes with the

holes in the valve body. Shift the man-

ual lever to the 1 detent, and place the

inner downshift lever between the

downshift lever stop and the downshift

valve.
The
manual valve must engage

the actuating
pin in the
manual detent

lever.

toward the center of the case until the

clearance is less than 0.050 inch, be-

tween the manual valve and the act-

uating pin on the manual detent lever.

specification. Be sure that the rear

fluid filter retaining clip is installed

under the valve body bolt as shown in

Figure 17.

13.
Install the tubes to the pressure

regulator and the control valve body.

14.
Turn the manual valve one full

turn in each manual lever detent posi-

tion. If the manual valve binds against

the actuating pin in any detent posi-

tion, loosen the valve body attaching

bolts and move the body away from

the center of the case. Move the valve

body only enough to relieve the bind-

ing. Torque the attaching bolts and

recheck the manual valve for binding.

15.

on the bottom of the transmission

case,
and install the pan. Torque the

pan screws to specification.

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
