For example, on a C4 transmission,

if the pressure at 10 inches of vacuum

was 120 psi and the pressure at 1.0

inch of vacuum was 170 psi, and up-

shifts and downshifts were harsh, a di-

aphragm adjustment to reduce the di-

aphragm assembly spring force would

be required.

If the pressure readings are low, an

adjustment to increase diaphragm

spring force is required.

To increase control pressure, turn

the adjusting screw in clockwise to re-

duce control pressure, back the adjust-

ing screw out by turning it counte-

rclockwise. One complete turn of the

adjusting screw (360 degrees) will

change idle line control pressure ap-

proximately 2-3 psi. After the adjust-

ment is made, install the vacuum line

and make all the pressure checks as

outlined in the Specification Section.

The diaphragm should not be ad-

justed to provide pressure below the

ranges shown in the Specification Sec-

tion in order to change shift feel. To

do so could result in soft or slipping

shift points and damage to the trans-

mission.

ALTITUDE

COMPENSATING TYPE

The altitude—compensating di-

aphragm is provided with an adjust-

ment screw located in the vacuum

connecting tube (Fig. 15). The adjus-

table feature allows control and TV

pressures to be adjusted (within limits)

to correct soft or harsh shift feel.

Control and TV pressures are in-

creased or decreased by turning the

adjusting screw.

Before replacing or adjusting the di-

aphragm, it must first be determined

that the pressure or vacuum is actual-

ly out of specification and that the

cause of the problem is not due to

other items within the transmission or

vacuum connecting lines.

If the tests outlined in the Specifi-
cation Section have been performed

and pressures are within specification

but shift feel is unsatisfactory, or if

the pressure is too high or too low at

10 inches of vacuum, the vacuum di-

aphragm may be adjusted to improve

the shift feel.

If shifts are excessively harsh, the

diaphragm should be adjusted to re-

duce control pressure by backing off

the adjusting screw (counterclock-

wise).
If shift quality is extremely soft,

control pressure should be increased

by turning the adjusting screw inward

(clockwise).

To adjust the vacuum diaphragm to

compensate for harsh shift quality,

first check control pressure in D, 2

and 1 at 10 inches manifold vacuum

and note the pressure reading ob-

tained. Remove the T-fitting from the

vacuum hose and back off the adjust-

ing screw (counterclockwise) by one

full turn. Each full turn will reduce

control pressure by approximately 2

1/2 psi at 10 inches of vacuum. Test

the vehicle for shift feel. If shift quali-

ty is still harsh, a further adjustment

should be made to reduce control

pressure. However, control pressure

should not be reduced below the speci-

fication shown for 10 inches of vacu-

um. If control pressure has been re-

duced to the low limit and shift feel is

still excessively harsh, the clutches and

band should be checked for correct

operation.

To adjust the vacuum diaphragm to

compensate for extremely soft shifts,

record the control pressure reading at

10 inches of vacuum in D, 2 and 1,

then make an initial adjustment of

one full turn inward (clockwise). Test

the vehicle for shift feel and again ad-

just the diaphragm, if necessary. Con-

trol pressure at 10 inches of vacuum

must not exceed the high limit shown

in the Specification Section.

When the necessary adjustments

have been completed and shift feel is

satisfactory, repeat all the tests out-

NEUTRAL START SWITCH

ADJUSTMENT AND

REPLACEMENT—COLUMN SHIFT

There are two types of column-

mounted neutral start switches: A and

B.
Type A switch has a parking brake

brake-release vacuum valve. Type B

switches do not have a vacuum valve.

The switches differ in appearance but

not in operation. Both switches are

actuated by a removable steel lever,

which is installed in the shifter tube

within the steering column assembly.

The following procedures outline the

steps necessary to correctly adjust and

replace the neutral start switch.

SWITCH ADJUSTMENT

Neutral Position

1.
With the selector lever held light-

ly against the neutral stop, attempt to

start the engine. If the engine starts

while holding the lever but does not

start when the lever is released, the

shift linkage should be adjusted. If the

engine does not start in either condi-

tion, adjust the switch.

2.
To adjust the switch in neutral,

place the transmission selector lever

against the stop of the neutral detent

position.

3.
Loosen the two retaining screws

that locate the switch on the steering

column (Fig. 16).

4.
With the selector lever against

the neutral stop, rotate the switch

until a start in the neutral position is

obtained. Then, tighten the switch at-

taching screws to 20 in-lbs torque.

5.
With the switch properly adjust-

ed in neutral, place the selector lever

in the 1 position and push the park

reset button (Fig. 16) to the left

(counterclockwise) until it stops. The

park reset must be performed when-

ever the switch has been adjusted.

Park Position

1.
Place the selector lever in the

park position, release the lever and at-

tempt to start. If the engine does not

start, reset the park adjustment.procarmanuals.com

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.
