1964 CHEVROLET CORVETTE Owners Manual

IDriving with the Manual Transmission-s
Both Corvette
manual transmissions are controlled slowing down, shift into the next lower gear before
by the shift lever located on top of the Hoor tunnel. the engine
"lugs" or labors.
You will find the shift pattern for your transmission Do not "ride" the dutch. Depress the pedal only pictured on a plate just behind the shift lever. Dur- when actually shifting the transmission and then ing acceleration, always shift into the next higher clear to the Hoar. Use your brakes rather than the
gear before the engine
begins to oVeISeeed; and ,;h_e_n~ __ cl_u_ tch_ pedal to hold your Corvette on a hill.
THREE-SPEED •
TRANSMISSION
The optional fouf4speed manual transmISSIOn pro­vides four forward speeds. The closely spaced ratios
make it possible for you to accelerate with a mini­
mum loss of engine rpm at the shift points. You will
en joy the performance and feel of a direct connecte d
engi ne. Since all forward speeds afe synchronized
the transmission can be used to assist in deceleration
by downshifting in the third-second-first sequence.
The Corvette three-speed manual transmission is de­signed to provide high performance under ordinary
driving conditions as well as during high speed opera­
tion. Gear ratios were selected to keep the engine
operating in its high output range as consistently as possible and permit upshifting and downshifting
between second and third speed at high speeds.

TRANSMISSION

Downshifting with
Manual Transmission
If you wish to shift from one gear to the one imme ­
di ately lower in ratio, avoid dangerous ly overspeed­
ing the engine by downshifting as follows:
I.
Watch the Tachometer-If your tach is orange­
zoned at 5000 to 5300 rpm, you may downshift to
the next lower gear when it indicates 4000 to 4100
rpm. If your tach is red-zoned at 6300 to 6500 rpm, you may downshift to the next lower gear at 4700 to 4900 rpm.
2. Double-clutching reduces strain on engines and transmissions. The usual method of double ­
clutching is:
Let up on the throttle, disengage the clutch, shift
into neutral, and engage the clutch. Almost si­multaneously, speed up the engine, disengage the
clutch, shift into the next lower gear and re­engage the clutch while depressing the throttle.
With practice , this procedure becomes alm ost
second nature.
Driving with Positraction
The positraction rear axle will give you constant
driving force on both rear wheels, especially helpful in the winter and during other slippery driving con­
ditions which might stop a conventionally equipped vehicle. During turns , the positraction axle applies
the major driving force to the inside rear wheel thus
improving stability and cornering. Normal light throttle application will supply maximum traction.
When starting with one rear wheel on an excessive ly
slippery surface, slight application of the
parking brake may be necessary momentarily to gai n maxi­
mum traction.
Driving with
Metallic Brake Linings
If your Corvette is equipped with optional metallic
brake linings, you will find that somewhat mor e than
normal pedal pressure will be required to stop the car
until you have made several stops to warm up the
linings .

Pushing and Towing Tips
PUSHING CAR TO START
Should it ever beco me necessary to start the engine by
pu shing the car (towing to start is not recommended as car being towed may accelerate into tow car), pro­
ceed as fo llows: Turn off all e lect rical loads su ch as radio, heater
and, if possible, lights until the engine st arts.
MANUAL TRANSMISSION - T
urn ignition switch
to "on." Place shift leve r in high (3rd on 3-spee d
transmissions, 4th on four-speed) and depress clutch. When car reaches 25-30 miles per hour, slowly re­
l ease clutch to sta rt e ng ine.
POWERGLlDE TRANSMISSION -
Turn ignit io n
switch to "on" and place sel ector lever in "N." W h e n
car reac hes a spee d of 25-30 mph, place th e selecto r
l ever in l ever in uD." TOWING
A DISABLED CAR
If your Corvette must be towed, the following pre­
cautions must be observed:
MANUAL TRANSMISSION
-Release parking brake
and place shift lever in neutral.
POWERGLIDE TRANSMISSION -Release
parking brake and place selector lever in "N." DO NOT TOW IN EXCESS OF 30 MPH. II the transmission is inoperative, or not operating properly, the pro­peller shaft must b e d isconnected or car must be
towe d with rear wheels off the ground.
TOWING WITH REAR WHEELS
RAISED-When a
vehicle is being towed on its front wheels, the steer­
ing whee l shou ld be secured to maintain a straight
forward position.
Do
not use tire chains on the rear wheels of your Corvette . Clearance between
USE OF TIRE CHAINS
AND SNOW TIRES
• tire and wheelhouse is insufficient to permit operation with chains insta!led.
Many [ire manufa cturers market tires for the Corvette which have specialized
tread designs for mud and snow use.

CLUTCH AND STEERING ADJUSTMENTS-Your Chevrolet deal!!! '?I.n make these 'adjustments for YQu: • A linkage adjustment to reduce clutch pedal travel to permit .fast release and more rapid gear shifting; • An adjustment to move the steering wheel forward or rearward; _ A linkage IIdjustment to permit
"faster" steering
response.
TRAILERS and their EFFECT on CAR OPERATION
The Corvette is designed primaril y (or passenge r
co nveyance . H owever , it is well known that many owners do pull trailers and have experi e nced very
sa tisfacLOry serv ice.
When a trailer is attached to a car, the car becomes
not only a l oad-carrying vehicle, but a load-pulling vehicle . The d e m a n ds of this type of operation are
very different from those (or which t h e automobile is pri ma rily designed and may present probl ems, such
as spring and tire loading, braking, coo ling, lighting, and steering. Howeve r, careful driving practices will
better s atisfy the requirements of trailer hauling.
If in the opinion of the manufacturer a part or com ­ponent of a motor vehicle has been advers ely affected
by misuse of the vehicle with trailer loads, such part or
com
ponent will not be covered by the manufac­turers warranty .
The size o f and equipment for trailers, including
su ch ite ms as hitc hes and safe t y ch a ins, brakes, ligllls, pO\ve r- wei ght ratios a n d over-all length, are gen erally
su bject to safet y regulations in all states, and i t is the responsibility o f the u ser to m a ke certain that h e is in full compliance with th e regulations of the states
in which h e plans to opera te with a traile r and of t h e Interstate Commerce Commission, i f applicable,
before doing so . Furthe r , when opera tin g a car with a traile r attached, the drive r must realize tha t the performance, steering characte ri stics , a n d brakin g distance of his ca r h ave been altered , and that h e mlls t exe r c ise greater caution t o safe ly handle his
ca r and trailer.

INSTRUMENTS AND CONTROLS

SPEEDOMETER
AND
ODOMETER
..
TACHOMETER
The tachometer indicates
the speed of the engine in revolutions per minute. Two different tachome­ters are used in the Cor­
vette, depending upon the engine option installed
in the vehicle.
The speedometer, indicating the forward speed of
your Corvette in miles per hour, is calibrated to a
maximum of 160. The odometer registers total ac­cumulated vehicle mileage and is useful in keeping
track of lubrication and maintenance intervals. Corvette
250
hp and 300 hp engines are equipped with a tachometer which has a orange zone from
5000 to 5300 rpm (indicating valve float area) , and a red zone from 5300 to 5500 (indicating maximum permitted rpm) .
The tachometer supplied with the Corvette 365 hp engine has an orange zone at 6300 to 6500. Don't permit the pointer to enter the red zone beyond
6500 rpm.
TRIP
ODOMETER
The trip odometer may be reset to zero by means of
the knurled knob extending beneath the instrument
cluster to the right of the steering column.
This in­
strument may be used to record trip mileages as well as during sports car rallies.

The ammeter shows the rate at which the battery is being charged or discharged. The Delcotron charg­
ing system is equipped 'with a regulator which con­
trol s the charge acco rding to battery requirements.
When the Delcotron generator is supp lying more
than the curre nt demand, the ammeter will show the
chargi ng rate while a disc harg e will be shown if
the
current demand is more than the Delcotron output.
With the battery fully charged , the charging rate will be 1m-\', thus giving an indication of battery condition.
OIL PRESSURE
GAUGE
...
The oil pressure gauge indicates the pressure at which
oil is being delivered to the various parts of the en·
gine requiring lubrication. Pressures registered by the
AMMETER
•
gauge
may vary acco rding to outside air temperatures or weight of oil being used. Oil pressure of a cold en­
gine being operated at a given speed will be somewhat
higher than when the engine is at normal operating
temperature at the sam e speed. Prolonged high speed operation on a hot day at the giv en speed will result in somewhat lower oil pressure readings. Readings of 30 to 40 psi may be considered normal during moderate road speeds of 35 to 40 mph with the en­
gine at proper operating temperature. Gauge read­
in gs whi ch are consistently high or low under these
co nCIitions may ind i cate lubrication system and/or
engine malfunctions.

FUEL
GAUGE
..
The ele ctr ically o p erated fuel gauge will indicate
th e amoun t o f fuel in the lan k when th e ig nition
switc h i s turned on. W hen the ignition switch is
turned off, the nee dle will not necessar ily retur n to the em pty mark.
TEMPERATURE
GAUGE
..
Showing engin e coo lant temperature, gauge readings w ill vary with air temp eratur e and operating condi­
tions. Hard driving or prolonged idling in very hot
weather may produc e above normal readings. The ignitio n swit ch must be o n [or accur ate r eadings.
CLOCK
..
Resetting the dock provides a utomatic regulat io n
providing ther e is an error, either fast o r slow, of at
lea st 3 minu tes. No regulat ion will be introd uced if
the clock is reset for an error of less than 3 minutes. When resetting, pull out the small knob and turn in the direction in whi ch you wi sh to set the hands­clockwise if the clock is slow, counterclockwi se if the clo ck is fast. Do not move the hand s pas t the cor­
rect time. Your clock should be cleaned and oiled periodi cally.
The courtesy lights beneath the o u ter
en ds of the dash p a nel, as well as the Sport Coupe dome light and the Con-
COURTESY vertible r ear compartment light, will
LIGHTS come on when eithe r door is opened. They may a lso be lighted by turning the headlight switch fully counter­clockwise past the slight resi stan ce.
