transmission CHEVROLET ASTRO 1996 Owners Manual

To release the hatch using the optional Keyless Entry
hand-held transmitter, see “Keyless Entry System”
in
the Index.
To release the hatch and unlock the doors from the
outside
of the vehicle, put
the key in the lock and
turn clockwise.
Then, pull up
on the hatch and open the right rear door
first. Grasp the handle and pull the door open.
The hatch and doors will automatically lock when the
hatch is shut.
If
the hatch is partially closed, the rear doors will lock
and you will need to use the key or the REAR HATCH
button to unlock them.
Also, see the Caution following “Hatch,” located in
this section.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number
of theft-deterrent
features, we know
that nothing we put on it can make
it impossible
to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it.
When you park your vehicle and open the driver’s door,
you’ll hear a chime reminding
you to remove your key
from the ignition and take
it with you. Always do this.
Your steering wheel will be locked, and
so will your
ignition and transmission. And remember to lock
the doors.

Ignition Positions
Use your ignition key to start your vehicle. The ignition key \
lets you turn the ignition switch
to five different positions.
C
ACCESSORY (A): This position lets you use things like
the radio and the windshield wipers when the engine is
off. To get into ACCESSORY, push in the key and turn
it toward
you. Your steering wheel will remain locked,
just as it was before
you inserted the key.
NOTICE:
Don’t operate accessories in the ACCESSORY
position for long periods
of time. Prolonged
operation of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
LOCK (B): This position locks your ignition, steering
wheel and transmission shift lever
in PARK (P). It’s a
theft-deterrent feature. You will only be able to remove
your key when the ignition is turned to
LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. Use
OFF if you must have
your vehicle in motion while the engine is off (for
example,
if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This starts your engine.

NOTICE:
If your key seems stuck in LOCK and you can’t
turn it, be sure it is all the way
in. If it is, then
turn the steering wheel left and right while you
turn the key hard. But turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch.
If none of this
works, then your vehicle needs service.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start
in any other position -- that’s a
safety feature.
To restart when you’re already moving,
use NEUTRAL (N) only.
NOTICE:
Don’t try to shift to PARK (P) if your vehicle is
moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. Without pushing the accelerator pedal, turn your
ignition key
to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
I
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
~
damage your starter motor. ,

Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
, ’
I
It is dangerous to get out of your vehicle if the
shift lever
is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
CAUTION: (Continued)
I I
I CAUTION: (Continued)
Don’t 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 won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to
PARK (P).
See “Shifting Into PARK (P)” in the Index. If
you’re pulling a trailer, see “Towing a Trailer”
in the Index.
I
v
Ensure the shift lever is fully in PARK (P).range
before starting the engine. Your vehicle has a
brake-transmission shift interlock. You have to fully
apply your regular brakes before you can shift from
PARK
(P) when the ignition key is in the RUN position.
If you cannot shift out of PARK
(P), ease pressure on’
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear you wish. See
’‘Shifting Out of PARK
(P)” in this section.
2-1s

REVERSE (R): Use this gear to back up.
1 NOTICE:
Shifting to REVERSE (R) while your vehicle is
moving forward could damage your transmission.
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, see
“Stuck: In Sand, Mud, Ice or Snow” in the Index.
NEUTRAL (N): In this position, your engine doesn’t
connect with the wheels.
To restart when you’re already
moving, use NEUTRAL
(N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
A CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is “racing” (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people
or objects. Don’t shift out of
PARK (P) or
NEUTRAL (N) while your engine is racing.
I NOTICE:
Damage to your transmission caused by shifting
out of
PARK (P) or NEUTRAL (N) with the
engine racing isn’t covered
by your warranty.

DRIVE (D): This position is for normal driving. If you
need more power for passing, and you’re:
Going less than about 35 mph (56 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (56 km/h) or more, push the
accelerator pedal all the way down. You’ll shift
down to
the next gear and have more power.
DRIVE
(D) should be used for normal trailer towing.
THIRD
(3): This position is also used for normal
driving, however it offers more power and lower
fuel
economy than DRIVE (D). You should use THIRD (3)
when carrying a heavy load or driving on steep hills.
SECOND
(2): This position gives you more power but
lower fuel economy.
You can use SECOND (2) 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.
If you manually select SECOND
(2)’ the transmission
will drive
in second gear. You may use this feature
for reducing torque to
the rear wheels when you are
trying to start your vehicle from a stop on slippery
road surfaces. FIRST
(1): This
position gives you even more power
(but lower
fuel economy) than SECOND (2). You can .
use it on very steep hills, or in deep snow or mud. If the
selector lever is put
in FIRST (1)’ the transmission
won’t shift
into first gear until the vehicle is going
slowly enough.
NOTICE:
If your rear wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against
a solid
object. You could damage your transmission or
transfer case or both.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use your brakes or shift into
PARK
(P) to hold your vehicle in position on
a hill.
2-20

Leaving Your Vehicle With the
E.noiqe Rmnnjnq
r
can be ( lgerous to we your vt cle wi
the engine running. Your vehicle could move
suddenly if the shift lever
is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have
to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you’ve moved the shift lever into the PARK (P)
position, hold the regular brake pedal down. Then, see
if you can move
the shift lever away from PARK (P)
without first pulling it toward
you. If you can, it means
that the shift lever wasn’t fully locked into PARK (P).
Torque Lock I
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 find 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 find out how, see “Shifting Into
PARK (P)” in the Index.
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 transmission, so you can pull the shift
lever out
of PARK (P).
2-24

Shifting Out of PARK (P)
Your vehicle has a brake-transmission shift interlock.
You have to fully apply your regular brake before you
can shift from PARK (P) when the ignition is in the
RUN position. See “Automatic Transmission” in
the Index.
If
you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK
(P) as you maintain brake application. Then
move the shift lever into the gear
you want.
If
you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
I. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid
. levels and also the brakes, tires, cooling system and
transmission. These parts can work hard
on
mountain roads.
0 Know how to go down hills. The most important
thing to know is this: let your engine do some
of the
slowing down. Shift to
a lower gear when you go
down a steep or long hill.
~~~
A CAUTION:
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking
or even none going
down
a hill. You could crash. Shift down to let
your engine assist your brakes on
a steep
downhill slope. Coas ,g
downhill in
NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do
all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down
a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.
0 Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine and transmission, and you can climb the hill better.
0 Stay in your own lane when driving on two-lane
roads
in hills or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay
in your own lane.
0 As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.
0 You may see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area
or winding
roads. Be alert
to these and take appropriate action.
