is at the full mark on the dip stick, it is just slightly be-
low the planetary gear unit. If additional oil is added,
bringing the oil level above the full mark, the planetary
unit will run in the oil, foaming and aerating the oil. This
aerated oil carried through the various oil pressure pas-
sages (low servo, reverse servo, clutch apply, converter,
etc.) may cause malfunction of the transmission assem-
bly, resulting in cavitation noise in the converter and
improper band or clutch application. Overheating may
also occur.
If the transmission is found consistently low on oil, a
thorough inspection should be made to find and correct
all external oil leaks.
PERIODIC OIL CHANGE
The transmission oil should be changed periodically as
recommended in Section 0, and whenever transmission is
to be removed from the vehicle for repairs.
1.
Run engine for one minute in neutral prior to chang-
ing.
2.
Be sure vehicle is level or raise from the rear only.
3.
Remove the oil pan drain plug and allow oil to drain
thoroughly into a pan or can.
Replace drain plug and refill with approximately two
quarts of oil specified in Section 0.
NOTE: To refill the transmission, remove dip
stick from oil filler tube and refill transmission
with oil specified in Section 0 using filler tube
and funnel J-4264. Then, after shifting into all
ranges at idle speed to fill all oil passages, the
engine should be run at 800-1000 rpm with the
transmission in Neutral until the oil warms up,
then add oil as required to raise the fluid level
to the full mark on the dip stick. Refill capacity
is approximately 2 qts.

GENERAL DESCRIPTION
The regular production steering gear
is the
recirculat-
ing ball type. This gear provides
for
ease
of
handling
by
transmitting forces from worm
to
sector gear through
ball bearings.
The
steering linkage
is of
the relay type,
and extended interval lubrication design, with the pitman
arm connected
to one end of
the relay
rod. The
other
end
of
the
relay
rod is
connected
to an
idler
arm
which
is
connected
to the
frame side rail opposite
the
steering
gear.
Two
adjustable
tie
rods connect
the
relay
rod to
the steering arms.
All passenger
car
models
for 1967 are
equipped with
new energy absorbing steering columns.
The
mast jacket,
shift tube,
and
steering shaft
are
designed
to
collapse
under various front impact conditions.
All new
columns
are
of
this design, including
the
tilt option and telescope
option.
MAINTENANCE
AND
ADJUSTMENTS
The manual steering gear
is
filled
at the
factory with
a
water resistant grease. Seasonal change
of
this lubrica-
tion
is
unnecessary and
the
housing should
not be
drained.
The steering gear lubricant level should
be
checked every
36,000 miles. Whenever required, additions should
be
made using
a
water resistant
EP
chassis lubricant.
Check and fill steering gear
as
follows:
1.
Remove lower
and
outboard cover retaining screws
(fig.
1).
2.
Insert filling device
in
lower screw hole.
3.
Inject lubricant until
it
appears
in
outboard screw
hole; gear
is now
filled
to
correct level.
The steering linkage should
be
lubricated with water
resistant
EP
chassis lubricant every 6,000 miles
or six
months, whichever occurs first. Lubrication points
and
additional information
on the
chassis lubricant
to be
used
can
be
found
in
Section
0 --

STEERING
GEAR
Before any adjustments are made to the steering gear
in an attempt to correct such conditions as shimmy,
loose or hard steering etc., a careful check should be
made of front end alignment, shock absorbers, wheel
balance and tire pressure for possible cause.
Correct adjustment of the steering gear is very im-
portant. Perform adjustments following the sequence
listed below,
1.
Remove pitman arm nut and mark relation of pitman
arm position to sector shaft. Remove pitman arm
with Tool J- 6632 as shown in Figure 2.
2.
Loosen the pitman shaft lash adjuster screw locknut
and turn the adjuster screw a few turns in a counter-
clockwise direction (fig. 3). This removes the load
Fig. 2—Removing Pitman Arm
imposed on the worm bearings by the close meshing
of rack and sector teeth. Turn steering wheel gently
in one direction until stopped by gear, then back away
about one turn.
CAUTION: Do not turn steering wheel hard
against stops when steering relay rod is discon-
nected as damage to ball guides may result.
3.
All except Corvette and telescopic columns:
a. Disconnect steering column harness at chassis
wiring connector plug.
b.
Remove horn cap or ornament and using an inch
pound torque wrench and socket on steering wheel
nut, measure torque required to keep the wheel
in motion.

necessary.
4.
Corvette and telescopic columns:
a. Use Tool J-5178 to measure.pull at rim of wheel
required to keep wheel in motion (fig. 4).
b.
If pull does not lie within limits given in specifi-
cations in rear of manual, adjustment of worm
bearings is necessary.
NOTE:
If vehicle is equipped with a tilt steer-
ing column, it will be necessary to disconnect
the steering coupling to obtain a torque reading
of the steering column. This torque should then
be subtracted from any reading taken on the
gear.
5. To adjust worm bearings, loosen worm bearing ad-
juster locknut and turn worm bearing adjuster shown
in Figure 3 until there is no perceptible end play in
worm. Check pull at steering wheel, readjusting: if
necessary to obtain proper pull. Tighten locknut and
recheck pull. If the gear feels "lumpy" after adjust-
ment of worm bearings, there is probably damage in
the bearings due to severe impact or to improper
adjustment and the gear must be disassembled for
replacement of damaged parts.
6. After proper adjustment of worm is obtained and all
mounting bolts securely tightened, adjust lash ad-
juster screw. First turn the steering wheel gently
from one stop all the way to the other, carefully
counting the total number of turns. Then turn wheel
back exactly half way, to center position. Turn lash
adjuster screw clockwise to take out all lash in gear
teeth, and tighten locknut. Check pull at steering
wheel taking highest reading as wheel is turned
through center position. See specifications in rear of
manual for proper sector lash adjustment. Readjust
if necessary to obtain proper pull.
