2003 CHEVROLET CORVETTE transmission

NEUTRAL:Use this position when you start or idle
your engine. Your shift lever is in NEUTRAL when it is
centered in the shift pattern, not in any gear.
REVERSE (R):To back up, press down the clutch
pedal and shift into REVERSE (R). Just apply pressure
to get the lever past FIFTH (5) and SIXTH (6) into
REVERSE (R). Let up on the clutch pedal slowly while
pressing the accelerator pedal.
Your six-speed manual transmission has a feature that
allows you to safely shift into REVERSE (R) while
the vehicle is rolling (at less than 3 mph (5 km/h)). You
will be locked out if you try to shift into REVERSE (R)
while your vehicle is moving faster than 3 mph (5 km/h).
If you have turned your ignition off and wish to park
your vehicle in REVERSE (R), you will have to move the
shift lever quickly to the right, and immediately forward
into gear.Shift Speeds (Manual Transmission)
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Don't shift down
more than one gear at a time when you
downshift.
This chart shows when to shift to the next higher gear
for the best fuel economy.
2-28

If your engine speed drops below 900 rpm, or if the
engine is not running smoothly, you should downshift to
the next lower gear. You may have to downshift two
or more gears to keep the engine running smoothly or
for good engine performance.
Notice:When you are shifting gears, don't move
the gearshift lever around needlessly. This can
damage parts of the transmission and may require
costly repair. Shift directly into the next appropriate
gear.
One to Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to turn off
this feature. This helps you get the best possible fuel
economy.After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.
Notice:Do not try to force the shift lever into
SECOND (2) or THIRD (3) when the 1 TO 4 SHIFT light
comes on. Do not try to re-engage FIRST (1) after
starting to shift into FOURTH (4). You will damage
your transmission. Shift only from FIRST (1) to
FOURTH (4) when the light comes on.
This light will come on when:
·The engine coolant temperature is higher than
169ÉF (76ÉC),
·you are going 15 to 19 mph (24 to 31 km/h) and
·you are 21 percent throttle or less.
Downshifting (Manual Transmission)
If your vehicle is a coupe or convertible, do not downshift
into the gear shown below at a speed greater than
shown in the table:
FIRST (1) 50 mph (80 km/h)
SECOND (2) 74 mph (119 km/h)
THIRD (3) 101 mph (163 km/h)
FOURTH (4) 130 mph (209 km/h)
2-29

If your vehicle is a Z06, do not downshift into a gear
shown below at a speed greater than shown in the table:
FIRST (1) 48 mph (77 km/h)
SECOND (2) 69 mph (111 km/h)
THIRD (3) 100 mph (161 km/h)
FOURTH (4) 143 mph (230 km/h)
Notice:If you skip more than one gear when you
downshift, or if you race the engine when you
release the clutch pedal while downshifting, you
could damage the engine, clutch, driveshaft or the
transmission.
The six-speed transmission has a spring that centers
the gearshift lever near THIRD (3) and FOURTH (4).
This spring helps you know which gear you are in when
you are shifting. Be careful when shifting from
FIRST (1) to SECOND (2) or downshifting from
SIXTH (6) to FIFTH (5). The spring will try to pull the
gearshift lever toward FOURTH (4) and THIRD (3).
Make sure you move the lever into SECOND (2)
or FIFTH (5). If you let the gearshift lever move in the
direction of the pulling, you may end up shifting
from FIRST (1) to FOURTH (4) or from SIXTH (6) to
THIRD (3).
Parking Brake
To set the parking brake, hold the brake pedal down.
Pull the parking brake lever up. If the ignition is on, the
brake system warning light will come on.
2-30

To release the parking brake, hold the brake pedal
down. Then push the release button in as you move the
parking brake lever all the way down.
Notice:Driving with the parking brake on can
cause your rear brakes to overheat. You may have
to replace them, and you could also damage
other parts of your vehicle. Make sure the brake
warning light is not on before driving.
Shifting Into Park (P)
(Automatic Transmission)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake ®rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle won't
move, even when you're on fairly level ground,
use the steps that follow.
1. Hold the brake pedal down with your right foot and
set the parking brake.
2-31

2. Move the shift lever into PARK (P) by holding in the
button on the lever and pushing the lever all the
way toward the front of the vehicle.
3. Turn the ignition key to OFF.
4. Remove the key and take it with you. If you can
remove the key from the ignition, the vehicle is in
PARK (P).
Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake ®rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch ®re.
You or others could be injured. Don't leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is ®rmly set before you leave it. After
you've moved the shift lever into PARK (P), hold down
the regular brake pedal. See if you can move the
shift lever away from PARK (P) without ®rst pulling it
toward you. If you can, it means that the shift lever
wasn't fully locked into PARK (P).
2-32

Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may ®nd it difficult to pull the
shift lever out of PARK (P). This is called ªtorque
lock.º To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave
the driver's seat. To ®nd out how, see ªShifting
Into PARK (P)º listed previously in this section.
When you are ready to drive, move the shift lever out of
PARK (P)
beforeyou release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply your regular
brake before you can shift from PARK (P) when
the ignition is in ON. See
Automatic Transmission
Operation on page 2-24.
As a reminder, you will see a message in the Driver
Information Center (DIC) that will say PRESS BRAKE
BEFORE SHIFT within 15 seconds unless the brake
is pressed.
If you cannot shift out of PARK (P), ease pressure on
the shift lever ± push the shift lever all the way into
PARK (P) and release the shift lever button as
you maintain brake application. Then press the shift
lever button and move the shift lever into the gear
you wish.
2-33

If you ever hold the brake pedal down but still can't shift
out of PARK (P), try this:
1. Turn the key to ACCESSORY.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and then shift to the drive gear
you want.
5. Have your vehicle inspected by your dealer as soon
as possible.
Parking Your Vehicle
(Manual Transmission)
Before you get out of your vehicle, move the shift lever
into REVERSE (R) and ®rmly apply the parking
brake. Once the shift lever has been placed into
REVERSE (R) with the clutch pedal pressed in, you can
turn the ignition key to OFF, remove the key and
release the clutch.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't park
over papers, leaves, dry grass or other things
that can burn.
2-34

Running Your Engine While You
Are Parked (Automatic
Transmission)
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust Ð with CO Ð can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
ªWinter Drivingº in the Index.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake ®rmly set. Your vehicle can
roll. Don't leave your vehicle when the engine
is running unless you have to. If you've left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle won't move, even when
you're on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See
Shifting Into Park (P) (Automatic
Transmission) on page 2-31.
