FIG. 21 -Typical
Rear Band Adjustment
Slacken the adjusting screw
i
turn
and tighten the locknut.
STARTER INHIBITOR
SWITCH
This particular component is
a
safety device to ensure that
the
engine will only start in "Park"
or
"Neutral" selector positions. If
the
engine will not start in the "P"
or
"N" selector positions, or the starter
motor operates in all selector posi-
tions, then the starter inhibitor
switch may require replacement.
Check the manual linkage adjust-
ment and wiring connections and
loom for faults.
If correction is not obtained the
switch must be replaced.
TRANSMISSION
FLUID DRAIN
AND REFILL
Normal maintenance and lubrica-
tion requirements do not
necessitate
periodic automatic transmission
fluid
changes.
If
a major failure, such
as
a
clutch,
band, bearing, etc., has occurred
within the transmission, it will
have
to be removed for service.
At
this
time the converter must
be thor-
oughly flushed to remove all
dirt.
When filling a dry transmissioQ
and converter, install 6
quarts of
fluid.
Start the engine, shift
the se-
lector lever as in Step 5
below, and
check and
add
fluid as necessary.
Following is the procedure for
partial drain and refill
due to minor
repairs.
1.
Place a drain pan
under the
transmission.
Loosen and remove
the drain plug and drain the fluid.
Remove and thoroughly clean the
oil pan and
screen.
Discard the oil
pan gasket.
l. Place a new gasket on the oil
pan, and install the screen and pan
oc the transmission.
3. Add three quarts of fluid to the
transmission through the filler tube.
4. Run the engine at idle speed for
about two minutes. Check the fluid
level, and add fluid
if
necessary. Run
the engine at fast idle speed
(about
1200 rpm) until it reaches
its
nor-
mal operating
temperature.
Do not
race the encine.
5. Shift the selector lever through
all the positions, place it at P, and
check the fluid level.
If
necessary,
add enough fluid to the transmission
to raise the level to the F (Full)
mark on the dipstick. Do not overfill
the transmission.
OIL COOLER FLUSHING
PROCEDURE
When
a
clutch or band failure or
other internal trouble has occurred
in the transmission, any metal par-
ticles or clutch plate or band mate-
rial that may have been carried into
the cooler should be removed from
the system by flushing the cooler
and lines before the transmission is
put back into service. In ·no case
should an automatic transmission
having a clutch or band failure or
other internal trouble resulting in
fluid
contamination,
be put back into
service without first flushing the
transmis~ion
oil cooler.
1. After installing a new or re-
built automatic
transmission and
converter
assembly in
the
car,
Do
Not Connect the Cooler Return Une
to the Transmission. Place the trans-
mission
selector
lever
in
the P
(park)
position and
connect
the
cooler inlet (converter
out)
line
to
the transmission. Place
a
pan under
the
end of the
cooler return
line that
will hold
transmission
fluid. Do Not
Start the Engine.
2. Install 8 quarts
of automatic
transmission
fluid
meeting
Ford
Specification.
3.
Start
the
engine
and allow
it
to run at normal
idle
speed with
the selector lever in P, park posi-
tion.
4. Allow
approximately
two
quarts of transmission fluid to drain
into
the pan placed under
the
end
of the cooler return line.
S.
If
the
fluid does not run clean
after draining two quarts of
it
through the
cooler,
shut off the en-
gine and add two additional quarts
of transmission fluid.
6. Repeat
steps
3
through
4 until
the transmission fluid flowing out
of the cooler return line is clean.
7.
If
there
is no fluid flow or the
fluid does not flow freely,
shut
off
the engine and disconnect both
cooler lines from the transmission
and cooler.
8. Use an
air
hose
with
not more
than I 00 psi air pressure to reverse
flush the cooler
lines
and the
cooler.
After reverse flushing, connect both
lines
at the cooler and the cooler
inlet
line (converter
out) to the
transmission.
9. Start
the engine
and check
the fluid flow
.
