2009 CHEVROLET COBALT transmission

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently to allow the oil to warm up
and lubricate all moving parts.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects components. If the ignition
key is turned to the START position, and then
released when the engine begins cranking, the
engine will continue cranking for a few seconds
or until the vehicle starts. If the engine does not start
and the key is held in START for many seconds,
cranking will be stopped after 15 seconds to prevent
cranking motor damage. To prevent gear damage,
this system also prevents cranking if the engine
is already running. Engine cranking can be stopped
by turning the ignition switch to ACC/ACCESSORY
or LOCK/OFF.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor and holding it there as you
hold the key in START for up to a maximum
of 15 seconds. Wait at least 15 seconds between
each try, to allow the cranking motor to cool
down. When the engine starts, let go of the key
and accelerator. If the vehicle starts briey but
then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race
the engine immediately after starting it. Operate
the engine and transmission gently until the
oil warms up and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, your
engine might not perform properly. Any resulting
damage would not be covered by your vehicle’s
warranty.

Automatic Transmission Operation
If your vehicle has an automatic transmission, the
shift lever is located on the console between the seats.
There are several
different positions
for the automatic
transmission.
PARK (P):This position locks your front wheels.
It is the best position to use when you start your
engine because your vehicle cannot move easily.{CAUTION:
It is 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.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure
your vehicle will not move, even when you are
on fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
SeeShifting Into PARK (P) (Automatic
Transmission) on page 2-33. If you are pulling
a trailer, seeTowing a Trailer (Manual
Transmission) on page 4-34orTowing a Trailer
(Automatic Transmission) on page 4-34.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You have
to fully apply your regular brakes rst and then
press the shift lever button before you can shift from
PARK (P) when the ignition key is in ON/RUN.
2-28

If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the way
into PARK (P) as you maintain brake application.
Then press the shift lever button and then move
the shift lever into another gear. SeeShifting Out of
PARK (P) (Automatic Transmission) on page 2-35.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 4-26.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be covered
by your warranty. Be sure the engine is not running
at high speed when shifting your vehicle.
DRIVE (D):This position is for normal driving with
the automatic transmission. It provides the best
fuel economy for your vehicle. If you need more
power for passing, and you are:
Going less than about 35 mph (55 km/h),
push your accelerator pedal about halfway down.
Going about 35 mph (55 km/h), push your
accelerator all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-15.
2-29

INTERMEDIATE (I):This position is also used for
normal driving. However, it reduces vehicle speed
without using your brakes for slight downgrades
where the vehicle would otherwise accelerate due
to steepness of grade. If constant upshifting or
downshifting occurs while driving up steep hills, this
position can be used to prevent repetitive types of shifts.
You might choose INTERMEDIATE (I) instead of
DRIVE (D) when driving on hilly, winding roads and
when towing a trailer, so that there is less shifting
between gears.
LOW (L):This position reduces vehicle speed
more than INTERMEDIATE (I) without actually using
your brakes. You can use it on very steep hills,
or in deep snow or mud. If the shift lever is put in
LOW (L), the transmission will not shift into LOW (L)
until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.Manual Transmission Operation
This is your shift pattern.
Here is how to operate your manual transmission:
FIRST (1):Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal
as you press the accelerator pedal.
You can shift into FIRST (1) when you are going less
than 20 mph (32 km/h). If you have come to a complete
stop and it is hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch pedal. Press
the clutch pedal back down. Then shift into FIRST (1).
SECOND (2):Press the clutch pedal as you let up
on the accelerator pedal and shift into SECOND (2).
Then, slowly let up on the clutch pedal as you press
the accelerator pedal.
2-30

THIRD (3), FOURTH (4) and FIFTH (5):Shift into
THIRD (3), FOURTH (4) and FIFTH (5) the same way
you do for SECOND (2). Slowly let up on the clutch
pedal as you press the accelerator pedal.
To stop, let up on the accelerator pedal and press
the brake pedal. Just before the vehicle stops, press
the clutch pedal and the brake pedal, and shift to
NEUTRAL.
NEUTRAL:Use this position when you start or idle
your engine.
REVERSE (R):To back up, press down the clutch
pedal and shift into REVERSE (R). Let up on the clutch
pedal slowly while pressing the accelerator pedal.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
Also, use REVERSE (R), along with the parking brake,
for parking your vehicle.Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you could
lose control of your vehicle. You could injure
yourself or others. Do not shift down more than
one gear at a time when you downshift.
Up-Shift Light
If you have a manual
transmission, you may
have an up-shift light.
This light will show
you when to shift to the
next higher gear for
the best fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road, and traffic conditions let
you. For the best fuel economy, accelerate slowly
and shift when the light comes on.
While you accelerate, it is normal for the light to
go on and off if you quickly change the position of
the accelerator. Ignore the light when you downshift.United States Only

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 will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer (Manual
Transmission) on page 4-34orTowing a
Trailer (Automatic Transmission) on page 4-34.To shift into PARK (P), do the following:
1. Hold the brake pedal down with your right foot
and set the parking brake. SeeParking Brake
on page 2-32for more information.
2. Move the shift lever into PARK (P) by holding in
the button on the shift lever and pushing the lever
all the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can
leave your vehicle with the key in your hand,
your vehicle is in PARK (P).
2-33

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. Do not leave
your vehicle with the engine running.
If you have to leave your automatic transmission 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 have moved the shift lever
into PARK (P), hold the regular brake pedal down.Then, 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 was not fully locked into
PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift 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 “torque lock.” 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, seeShifting Into PARK (P) (Automatic
Transmission) on page 2-33.
When you are ready to drive, move the shift lever out
of PARK (P) before you 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).
2-34

Shifting Out of PARK (P)
(Automatic Transmission)
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
Prevent ignition key removal unless the shift
lever is in PARK (P) with the shift lever button
fully released, and
Prevent movement of the shift lever out of
PARK (P) unless the ignition is in ON/RUN or
ACC/ACCESSORY and the regular brake pedal
is applied.
The shift lock release is always functional except in the
case of a an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-34for more
information.To shift out of PARK (P):
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of PARK (P):
1. Fully release the shift lever button.
2. While holding down the brake pedal, press the
shift lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from PARK (P),
consult your dealer/retailer or a professional towing
service.
Parking Your Vehicle
Before leaving your vehicle, fully press the clutch pedal
down, move the shift lever into REVERSE (R), and
rmly apply the parking brake. Once the shift lever has
been placed in REVERSE (R) with the clutch pedal
pressed down, you can turn the ignition key to OFF/
LOCK, remove the key and release the clutch pedal.
