2007 CHEVROLET COLORADO transmission

Four-Wheel-Drive Vehicles
Use the following procedure to tow your vehicle
from the rear:
1. Drive the vehicle onto the dolly.
2. Firmly set the parking brake. SeeParking
Brake on page 133for more information.
3. Put an automatic transmission in PARK (P)
or a manual transmission in FIRST (1).
4. Follow the dolly manufacturer’s instructions to
attach and secure the vehicle being towed to
the dolly and then the loaded dolly to the
tow vehicle.For manual transmission vehicles, make sure
the wheels are straight before proceeding
to the next steps. On automatic transmission
vehicles, use an adequate clamping device
to ensure that the front wheels are locked
into the straight position.
{CAUTION:
Shifting a four-wheel-drive vehicle’s
transfer case into NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P) for an
automatic transmission, or if your vehicle
is in gear, for a manual transmission.
You or others could be injured. Make
sure the parking brake is rmly set before
you shift the transfer case to NEUTRAL.
5. Shift the transfer case to NEUTRAL.
SeeFour-Wheel Drive on page 129for
more information.

Then, during the rst 500 miles (800 km)
that you tow a trailer, don’t drive over
50 mph (80 km/h) and don’t make starts
at full throttle. This helps your engine and
other parts of your vehicle wear in at the
heavier loads.
You may want to shift the transmission to
THIRD (3) or, if necessary, a lower gear
selection if the transmission shifts too
often (e.g., under heavy loads and/or hilly
conditions). If you have a manual transmission
and you are towing a trailer, it’s better not
to use the highest gear.
Three important considerations have to do
with weight:
the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig.
For example, speed, altitude, road grades, outside
temperature and how much your vehicle is used
to pull a trailer are all important. It can also depend
on any special equipment that you have on
your vehicle, and the amount of tongue weight
the vehicle can carry. See “Weight of the Trailer
Tongue” later in this section for more information.
Maximum trailer weight is calculated assuming
only the driver is in the tow vehicle and it has
all the required trailering equipment. The weight
of additional optional equipment, passengers
and cargo in the tow vehicle must be subtracted
from the maximum trailer weight.

Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could
be damaged. Avoid making very sharp
turns while trailering.
When you’re turning with a trailer, make wider turns
than normal. Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring and a heavy-duty turn signal asher.
The arrows on your instrument panel will ash
whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also
ash, telling other drivers you’re about to
turn, change lanes or stop.
When towing a trailer, the arrows on your
instrument panel will ash for turns even if
the bulbs on the trailer are burned out.Thus, you may think drivers behind you are seeing
your signal when they are not. It’s important to
check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before
you start down a long or steep downgrade.
If you don’t shift down, you might have to use
your brakes so much that they would get hot
and no longer work well.
When towing at high altitude on steep uphill
grades, consider the following: Engine coolant
will boil at a lower temperature than at normal
altitudes. If you turn your engine off immediately
after towing at high altitude on steep uphill grades,
your vehicle may show signs similar to engine
overheating. To avoid this, let the engine run
while parked (preferably on level ground) with
the automatic transmission in PARK (P) (or
the manual transmission out of gear and the
parking brake applied) for a few minutes before
turning the engine off. If you do get the overheat
warning, seeEngine Overheating on page 348.

Parking on Hills
{CAUTION:
You really should not park your
vehicle, with a trailer attached, on a hill.
If something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill,
here’s how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual
transmission. When parking uphill, turn your
wheels away from the curb. When parking
downhill, turn your wheels into the curb.
2. Have someone place chocks under the
trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.4. Reapply the regular brakes. Then apply your
parking brake, and then shift into PARK (P),
or REVERSE (R) for a manual transmission.
SeeParking Brake on page 133for more
information.
5. If you have a four-wheel-drive vehicle, be
sure the transfer case is in a drive gear
and not in NEUTRAL. SeeFour-Wheel
Drive on page 129for more information.
6. Release the regular brakes.
When You Are Ready to Leave
After Parking on a Hill
1. Apply your regular brakes and hold the
pedal down while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
of the chocks.
4. Stop and have someone pick up and
store the chocks.
