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.

- LI Range can be selected at any vehicle speed,

and the transmission will shift to second gear

and remain in second until vehicle speed is re-

duced to approximately 40 MPH, .depending on

axle ratio. LI Range position prevents the trans-

mission from shifting out of first gear.
It is very important that any communication concerning

the Turbo Hydra-Matic always contain the transmission

serial number and that all transmission parts returned

to Chevrolet Motor Division always be tagged with the

transmission serial number.

MAINTENANCE AND ADJUSTMENTS

TRANSMISSION FLUID

Transmission fluid level should be checked with trans-

mission warm and selector lever in "P" Park position,

every time engine oil level is checked or as specified in

Section 0 when engine oil is changed.

CAUTION: Since the Turbo Hydra-Matic trans-

mission is very sensitive to oil level, special

precautions should be taken when checking the

oil level, to insure against an overfifE

Transmission fluid should be changed as specified in

Section 0.

FLUID LEVEL INDICATOR

The fluid level indicator is located in the filler pipe at

the right rear corner of the engine. To bring the fluid

level from the add mark to the full mark add 1 pint.

Fluid level should be to the full mark with transmission

at normal operating temperature. With cold fluid the

level should be at the add mark or slightly below.

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 --
General Information
and

Lubrication.

ADJUSTMENTS

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.

c. If torque does not lie within limits given in speci-

fications at rear of manual, adjustment is

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.

8. Reassemble pitman arm to sector shaft, lining up

marks made during disassembly. Refer to torque

specifications at rear of manual for correct torque

value.

9. Install horn cap or ornament and connect steering

column harness at chassis connector.

NOTE:
Chevy.n models are equipped with a

shim at the frame to steering gear mounting

bolts.
Shims may be removed or installed as

required for proper steering gear alignment.

STEERING WHEEL ALIGNMENT AND

HIGH POINT CENTERING

1.
Set front wheels in straight ahead position. This can

be checked by driving vehicle a short distance on a

flat surface to determine steering wheel position at

which vehicle follows a straight path.

2.
With front wheels set straight ahead, check position

of mark on wormshaft designating steering gear high

point. This mark should be at the top side of the shaft

at 12 o'clock position and lined up with the mark in

the coupling lower clamp.

3.
If gear has been moved off high point when setting

wheels in straight ahead position, loosen adjusting

sleeve clamps on both left and right hand tie rods,

then turn both sleeves an equal number of turns in

the same direction to bring gear back on high point.

CAUTION: Turning the sleeves an unequal
number of turns or in differential directions will

disturb the toe-in setting of the wheels.

4.
Readjust toe-in as outlined in Section 3 (if necessary).

5. With wheels in a straight ahead position and the

steering gear on highpoint, check the steering wheel

alignment by measuring the distance from each hori-

zontal spoke to the horizontal centerline of the

steering wheel (fig. 5). If the horizontal spokes are

over 1-1/8 inches from the horizontal position the

wheel should be removed and centered. (See steering

wheel removal in this section.)
