line pressure.
All
line pressure adjustments
should fall within
the
limits specified
in the
table shown
for all
other push button positions.
b.
Governor Pressure (Refer
to
Fig. 24)
Remove
the
pipe plug from
the
governor pres-
sure take-off hole located
on the
lower left side
of
the
output shaft support
(Fig. 22).
Install
gauge, Tool C-3292
(100
psi.).
c. Lubrication Pressure
Remove
the
pipe plug
(or oil
cooler fitting)
from
the
lubrication pressure take-off hole
lo-
cated
on the
left side
of
the
transmission case
(Fig. 22). Install gauge, Tool C-3292 (100 psi.)
at this point. With engine running
at 800 rpm.
in neutral, lubrication pressure should
be
ap-
proximately
10
to
30 psi.
If
the
pressure
is
extremely high (above
50
psi.),
it is a
good indication that there
is a
restriction
due to
dirt
or
foreign matter
in the
lubrication passages.
d. Checking Throttle (Compensated) Pressure
Raise
the
vehicle
off the
floor (rear wheels free
to turn). Install gauge, Tool C-3292
(100 psi.)
at throttle pressure take-off plug. Refer
to Fig.
22.
Disconnect
the
bellcrank
to
transmission
throttle linkage
at
the
transmission. Start
the
engine, and place
the
transmission
in D
(drive)
position. While holding
the
transmission throt-
tle lever toward
the
closed throttle position
(against
the
internal stop) increase engine
speed slowly (using accelerator pedal
or
suit-
able throttle control fixture)
to
approximately
1500 rpm.
to
obtain an upshift into direct ratio.
After
the
shift takes place compensated throt-
tle pressure should read
26 to 32 psi. As
throt-
tle lever
(at
transmission)
is
advanced toward
full throttle, compensated throttle pressure
should begin
to
rise after
0° to 5°
movement.
If compensated throttle pressure rises imme-
diately when
the
lever
is
moved,
or
if
the
pres-
sure
is
incorrect
or
fails
to
rise after approxi-
mately
5°
movement, install
a
new
valve body.
Before stopping
the
engine, advance
the
throttle control lever
(at
transmission) slowly
and then return
to
closed throttle. Compensated
throttle pressure should rise
to
approximately
80
to 90
psi. and
then fall smoothly without
hesitation
and
should always return
to a
con-
sistent reading
at
closed throttle. Failure
to
do this indicates faulty throttle compensator
valve
or
throttle valve operation.

AND
INSTALLATION
a. Removal
Disconnect
one
of
the
cables
at the
battery.
At
rear
of
instrument panel, disconnect back-up
light switch, starting motor switch,
and
illumi-
nating lamp leads. Remove the two small screws
from face plate
(Fig. 25) to
expose
two
of
the
bezel retaining screws. Remove the three screws
securing bezel
to
