OTHER SERVICE OPERATIONS

Although certain operations, such as oil pan or gasket

replacement, valve body, governor, filler pipe "O" ring,

speedometer drive gear, case extension "0" ring and

rear oil seal, vacuum modulator, and servo cover or

gasket service may be performed from underneath the
vehicle without removing the Powerglide; their service

procedure is covered in the Passenger Overhaul Manual

and is not repeated here. Refer to the- Powerglide Sec-

tion of the Passenger Overhaul Manual for all other

service operations not covered here.

DIAGNOSIS

Proper operation of the Powerglide transmission may

be affected by a number of factors, all of which must be

considered when trouble in the unit is diagnosed.

Proper trouble diagnosis can only be accomplished

when performed in a thorough step by step procedure.

The following procedure has been devised and tested and

is recommended for all trouble diagnosis complaints and

if the service man will follow this checking procedure,

accurate and dependable diagnosis may be accomplished.

This will result in a savings of time, not only to the

service man, but to the customer as well.

WARMING UP TRANSMISSION

Before attempting to check and/or correct any com-

plaints on the Powerglide transmission it is absolutely

essential that the oil level be checked and corrected if

necessary. An oil level which is either too high or too

low can be the cause of a number of abnormal conditions

from excessive noise to slippage in all ranges.

It must be remembered that cold oil will slow up the

action of the hydraulic controls in the transmission. For

this reason a trouble or oil leak diagnosis should not be

attempted until the transmission has been warmed up by

either of the following procedures:

Shop Warm Up

1.
Connect tachometer to engine.

2.
Set parking brake tight and start engine.

3.
Place selector light in
"D"
(drive) range.

4.
Adjust carburetor idle speed adjusting screw to run

engine at approximately 750 rpm and operate in this

manner for two minutes. At the end of two minutes

of operation, the transmission will be sufficiently

warmed up for diagnosis purposes.
NOTE:
At this point, readjust the engine idle

speed to 450-475 rpm in
"D"
range.

Road Warm Up

Drive the car approximately 5 miles with frequent

starts and stops.

NOTE:
At this point, make sure the engine idle

speed is set to 450-475 rpm in
"D"
range.

CHECKING FLUID LEVEL AND CONDITION

After transmission has been warmed up, check the

fluid level with the engine idling, parking brake set and

control lever in "N" (neutral). If the fluid level is low,

add fluid to bring level up to the full mark on gauge rod,

CAUTION: If fluid level is too high, fluid may

be aerated by the planet carrier. Aerated fluid

will cause turbulence in the converter which will

result in lost power, lower stall speed and lower

pressures in control circuits. Lower fluid level

to full mark, then shut off engine to allow air

bubbles to work out of fluid.

When checking oil level, aburned smell and discolora-

tion indicate burned clutches or bands and the transmis-

sion will have to be removed.

MANUAL LINKAGE

Manual linkage adjustment and the associated neutral

safety switch are important from a safety standpoint.

The neutral safety switch should be adjusted so that the

engine will start in the Park and Neutral positions only.

With the selector lever in the Park position, the park-

ing pawl should freely engage and prevent the vehicle

CHEVROLET CHASSIS SERVICE MANUAL

CLUTCH AND TRANSMISSIONS 7-37

LI.
- 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.

SHIFT CONTROL LINKAGE ADJUSTMENT

Adjust linkage as shown below and in Figure 2.

1.
The shift tube and lever assembly must be free in the

mast jacket See Section 9 for alignment of steering

column assembly if necessary.

2.
To check for proper shift linkage adjustment, lift the

transmission selector lever towards the steering

wheel. Allow the selector lever to be positioned in

drive (D) by the transmission detent.

NOTE: Do not use the indicator pointer as a

reference to position the selector lever. When

performing linkage adjustment, pointer is ad-

justed last.

3.
Release the selector lever. The lever should be in-

hibited from engaging low range unless the lever is

lifted.

4.
Lift the selector lever towards the steering wheel,

and allow the lever to be positioned in neutral (N) by

the transmission detent.

5.
Release the selector lever. The lever should now be

inhibited from engaging reverse range unless the

lever is lifted.

6. A properly adjusted linkage will prevent the selector

lever from moving beyond both the neutral detent,

and the drive detent unless the lever is lifted to pass

over the mechanical stop in the steering column.

See schematic diagram.

7.
In the event that an adjustment is required, place the

selector lever in drive (D) position as determined by

the transmission detent. See Steps 2 and 3.

8. Loosen the adjustment swivel at the cross-shaft, and
rotate the transmission lever so that it contacts the

drive stop in the steering column.

9. Tighten the swivel and recheck the adjustment. See

Steps 2 and 6. -

l(h Readjust indicator needle if necessary to agree with

the transmission detent" positions. See Section 9.

11.
Readjust neutral safety switch if necessary to pro-

vide the correct relationship to the transmission de-

tent positions. See Section 12.

12.
When properly adjusted the following conditions must

be met by manual operation of the steering column

shift lever:

a. From reverse to drive position travel, the trans-

mission detent feel must be noted and related to

indicated position on dial.

b.
When in drive and reverse positions, pull lever

rearward (towards steering wheel) and then re-

lease. It must drop back into position with no

restrictions.

NEUTRAL SAFETY SWITCH ADJUSTMENT

The neutral safety switch must be adjusted so that the

car will start in the park or neutral position, but will not

start in the other positions. For replacement refer to

Section 12 of this Manual.

30—Standard Dual

All Corvettes
are
equipped with dual exhaust systems

(fig.
30).
Each exhaust assembly
is
connected
to its own

exhaust manifold
and
carries
the
exhaust gases
to the

rear, discharging them
on
each side
of
the rear bumpers.

The dual exhaust system includes
two
front
and
rear

exhaust pipe sections, mufflers, tail pipes and attaching

hardware.
The
system
is
suspended
on
brackets with

insulators
for
rattle free operation. Adjustment
is
only

required
at the
rear muffler bracket.
In addition
to the
regular dual system
an
optional side

mounted, off-road exhaust system
is
available
as an
RPO

(fig.
31).
Extending between front
and
rear wheels,
the

dual units
are
mounted outboard
of the
frame side rails

at
the
rocker panel level,
and
completely replaces
the

regular dual assemblies*

Flow characteristics
are
improved and back pressures

reduced
by
the more direct exhaust routing and
by the use

of chambered pipes
for
sound muffling
in
place
of con-

ventional mufflers.

SERVICE OPERATIONS

Proper relationship
of
parts
is
necessary
in the ex-

haust system
for
carefree operation. Annoying rattles

are usually
a
result
of
incorrect alignment
of
the exhaust

system
due to
incorrect clearances.

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
