2008 PONTIAC G6 transmission

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 4-19.
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. It
provides the best fuel economy for your vehicle. If you
need more power for passing, and you are:
Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have more
power.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-10.
Notice:If your vehicle seems to accelerate slowly
or not shift gears when you go faster, and you
continue to drive your vehicle that way, you could
damage the transmission. Have your vehicle
serviced right away. You can drive in LOW (L) when
you are driving less than 35 mph (56 km/h) and
DRIVE (D) for higher speeds until then.
2-28

THIRD (3):This position, available on the SE model, is
also used for normal driving. However, it reduces
vehicle speed more than DRIVE (D) without using your
brakes. Here are some times you might choose
THIRD (3) instead of DRIVE (D):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
LOW (L):This position, available on the SE model,
reduces vehicle speed more than THIRD (3) without
using your brakes. You can use LOW (L) on hills. It can
help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
You can use LOW (L) 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 rst gear until the
vehicle is going slowly enough.
Notice:Driving in LOW (L) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
LOW (L) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or DRIVE (D)
instead of LOW (L).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 MODE (M):This position, available on the
GT/GXP models, allows you to change gears similar to a
manual transmission. If your vehicle has this feature,
see Manual Shift Mode (MSM) following.
Manual Shift Mode (MSM) (Automatic
Transmission)
To use this feature, do the following:
1. Move the shift lever from DRIVE (D) rearward and
then to the right into the MANUAL MODE (M).
While driving in manual shift mode, the transmission
will remain in the driver gear selected.
2. Press the shift level forward to upshift or rearward
to downshift.
The odometer display on the instrument panel cluster
will change from the vehicle’s mileage to the letter M, for
manual shift mode, and a number indicating the
requested gear range when moving the shift lever
forward or rearward. SeeSpeedometer and Odometer
on page 3-29for more information.
2-29

While using the MSM feature the vehicle will have rmer
shifting and sportier performance. You can use this
for sport driving or when climbing hills to stay in gear
longer or to downshift for more power or engine braking.
The transmission will only allow you to shift into gears
appropriate for the vehicle speed and engine revolutions
per minute (RPM):
The transmission will not automatically shift to the
next higher gear if the engine RPM is too high.
The transmission will not allow shifting to the next
lower gear if the engine RPM is too high.
If the vehicle does not respond to a gear change, or
detects a problem with the transmission, the range
of gears may be reduced and the Malfunction Indicator
Lamp will come on. SeeMalfunction Indicator Lamp
on page 3-38for more information.
SECOND (2)/THIRD (3) Gear Start
Feature
Notice:If you attempt a third gear start while
trailering or towing a heavy load, you will notice
reduced engine power. This could overheat
and damage your transmission. Do not attempt a
third gear start while trailering or towing your
vehicle.
If your vehicle has the 6-speed transmission, when
accelerating your vehicle from a stop in snowy and icy
conditions, you may want to shift into SECOND (2),
or THIRD (3) gear. A higher gear, and light application
of the gas pedal, may allow you to gain more traction
on slippery surfaces.
With the MSM, the vehicle can accelerate from a stop in
SECOND (2) or THIRD (3).
1. Move the shift lever from DRIVE (D) into the
MANUAL MODE (M) position.
2. With the vehicle stopped, move the lever forward
towards the plus (+) to select SECOND (2) or
THIRD (3)gear. The vehicle will start from a stop
position in SECOND (2) or THIRD (3) gear.
3. Once the vehicle is moving select the desired
drive gear.

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 on
page 4-28.Use this procedure to shift into PARK (P):
1. Hold the brake pedal down with your right foot and
set the parking brake.
SeeParking Brake on page 2-31for 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. For vehicles with base ignitions, remove the key
and take it with you. If you can leave your vehicle
with the ignition key in your hand, your vehicle is in
PARK (P). Vehicles with the passive ignitions,
turn the passive key to the LOCK/OFF position.
Take the keyless access transmitter with you.

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 pushing the button.
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 your
automatic 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 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, see
“Shifting Into Park (P)” previously in the section.
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).

Running the Engine While Parked
It is 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
Engine Exhaust on page 2-35.
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 — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-15.
{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. 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 the
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into PARK (P) (Automatic
Transmission) on page 2-32.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-28.
