2003 CHEVROLET CORVETTE transmission

How to Check
Because this operation can be difficult, you may choose
to have this done at your dealership service department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading.
Notice:Too much or too little ¯uid can damage
your transmission. Too much can mean that some
of the ¯uid could come out and fall on hot engine
part or exhaust system parts, starting a ®re.
Too little ¯uid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission ¯uid.
Check the ¯uid level only when your engine is off, the
vehicle is parked on a level place and the transmission
is cool enough for you to rest your ®ngers on the
transmission case.Then, follow these steps:
1. Remove the ®ller plug.
2. Check that the lubricant level is up to the bottom of
the ®ller plug hole.
3. If the ¯uid level is good, install the plug and be sure
it is fully seated. If the ¯uid level is low, add more
¯uid as described in the next steps.

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to follow the steps below to do it safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
·They contain acid that can burn you.
·They contain gas that can explode or
ignite.
·They contain enough electricity to
burn you.
If you don't follow these steps exactly, some
or all of these things can hurt you.
Notice:Ignoring these steps could result in costly
damage to your vehicle that wouldn't be covered
by your warranty. Trying to start your vehicle
by pushing or pulling it won't work, and it could
damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other system isn't a 12-volt system
with a negative ground, both vehicles can be
damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake ®rmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brakes.
Notice:If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlet. Turn off
the radio and all lamps that aren't needed. This will
avoid sparks and help save both batteries. And it
could save your radio!

Tire Chains
{CAUTION:
Don't use tire chains. There's not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension or
other vehicle parts. The area damaged by the
tire chains could cause you to lose control of
your vehicle and you or others may be injured
in a crash. Use another type of traction device
only if its manufacturer recommends it for use
on your vehicle and tire size combination and
road conditions. Follow that manufacturer's
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it's contacting your vehicle, and don't
spin your wheels. If you do ®nd traction
devices that will ®t, install them on the
rear tires.
Lifting Your Vehicle
{CAUTION:
Lifting a vehicle can cause an injury. The
vehicle can slip off the jack and roll over you
or other people. You and they could be badly
injured. Find a level place to lift your vehicle.
To help prevent the vehicle from moving:
1. Set the parking brake ®rmly.
2. Put an automatic transmission shift lever
in PARK (P), or shift a manual
transmission to FIRST (1) or
REVERSE (R).
3. Turn off the engine.
To be even more certain the vehicle won't
move, you can put blocks in front of and
behind the wheels.

Z06 models do not have Extended Mobility Tires. If a
Z06 model tire goes ¯at, avoid further tire and wheel
damage by driving slowly to a level place and stopping.
Then do this:
1. Turn on the hazard warning ¯ashers.
2. Set the parking brake ®rmly.
3. Put the shift lever (manual transmission) in
REVERSE (R).
4. Turn off the engine.
5. Inspect the ¯at tire.
If the tire has been separated from the wheel or has
damaged sidewalls or large tears that allow rapid
air loss, call a tire repair facility. See
Roadside
Assistance Program on page 7-6.If the ¯at tire is due to a slow leak caused by a nail or
other similar road hazard, the tire in¯ator kit may
be used to repair the damaged tire temporarily. The kit
uses a liquid tire sealant to seal small punctures in
the tread area of the tire. The ¯at tire is then in¯ated to
at least 26 psi (179 kPa) and driven to evenly distribute
the tire sealant. The tire pressure is checked after
driving for a maximum of 10 minutes to see if the slow
leak has been stopped. If the tire pressure is 19 psi
(131 kPa) or more, in¯ate the tire up to the standard
operating pressure as shown on the Tire Pressure Label
found on the rear edge of the driver's door. See
In¯ation -- Tire Pressure on page 5-56.
You should have the damaged tire repaired as soon as
possible. The tire sealant is a temporary repair only.
For more information regarding the tire in¯ator kit
see ªTire In¯ator Kit (Z06 Only)º following this section.
Notice:If the tire pressure has dropped below
19 psi (131 kPa), the vehicle should not be driven
further. Damage to the tire may be severe and
the sealant will not be effective. Contact Roadside
Assistance. See ªRoadside Assistanceº in the Index.
5-69

Tire Sealant
The kit contains a liquid sealant that when injected into
a ¯at tire, may temporarily repair nail holes or cuts
in the tread area of the tire. The tire sealant cannot
repair tire damage caused while driving on a ¯at tire or
a tire that has had a ªblow outº or a tire that has
punctures in the sidewall areas. The tire sealant solution
is a one-time use application for one tire only. Check
the tire sealant expiration date; the sealant may not be
as effective beyond the expiration date. The tire
sealant can be peeled off easily after drying.
Notice:Do not use a tire sealant if your vehicle is
equipped with Extended Mobility Tires or tire
pressure monitors. The tire sealant can damage tire
pressure monitor sensors. See ªExtended Mobility
Tiresº in the Index.
Air Compressor
The air compressor included in the tire in¯ator kit, was
designed exclusively for the Z06 Model equipped
with P295/35ZR18 and P265/40ZR17 tires. After the
sealant has been injected into the ¯at tire, use the
air compressor to in¯ate the tire to at least 26 psi
(179 kPa). Instructions for connecting and using the air
compressor are located on the air compressor.A. In¯ating Hose
B. Air Pressure GageC. ON/OFF Switch
D. Air Compressor
Plug
Notice:The car engine must be running to avoid
draining the battery while running the air
compressor.
Follow the proper steps to be sure your vehicle won't
move. See
Parking Your Vehicle (Manual Transmission)
on page 2-34.

{CAUTION:
It can be dangerous to get out of your vehicle
with the engine running, if the shift lever is not
in NEUTRAL (N) with the parking brake ®rmly
set (manual transmission). Your vehicle can
roll or move suddenly even when on fairly
level ground. To be sure your vehicle won't
move, always set your parking brake and move
the shift lever to NEUTRAL (N) when you start
or idle your engine.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). See ªEngine
Exhaustº in the Index.
{CAUTION:
In¯ating something too much can make it
explode, and you or others could be injured.
Be sure to read the in¯ator instructions, and
in¯ate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
Notice:Do not allow the air compressor to operate
continuously for more than six minutes to help
prevent damage from overheating.
Notice:If 26 psi (179 kPa) tire pressure cannot be
reached after six minutes the vehicle should not
be driven further. Damage to the tire is severe and
the sealant will not be effective. Remove the air
compressor plug from the accessory power outlet
and unscrew the in¯ating hose from the tire
valve. See ªRoadside Assistanceº in the Index.
If 26 psi (179 kPa) tire pressure is reached in six
minutes or less, disconnect the air compressor and
attach the enclosed maximum speed label to the inside
upper left corner of the windshield or to the face of
the radio/clock.
