1995 GMC SIERRA automatic transmission

A CAUTION:
If your vehicle has air conditioning, the auxiliary electric fan
under the hood can
start up even when the engine is not running
and can injure you. Keep hands, clothing and
tools away from
any underhood electric fan.
-
NOTICE:
Ignoring these steps could result in costly damage to your
vehicle that wouldn’t be covered by your vehicle warranty.
Trying to start your vehicle by pushing or pulling it could
damage your vehicle, even if you have a manual transmission.
And if you have an automatic transmission,
it won’t start that
way.
To Jump Start Your Vehicle
1. Check the other vehicle. It must have a 12-volt battery with a negative
ground system.
NOTICE:
If the other system isn’t a 12-volt system with a negative
ground, both vehicles can be damaged.
If you have a diesel engine vehicle with two batteries (or more), you
should know before you begin that, especially in cold weather, you may
not be able to get enough power from a single battery
in another
vehicle to start your diesel engine.
If your vehicle has more than one battery, use the battery that’s on the
passenger side
of the vehicle - this will reduce electrical resistance.
2. Get the vehicles close enough so the jumper cables can reach, but be
sure the vehicles aren’t touching each other.
If they are, it could cause a
ground connection you don’t want.
You wouldn’t be able to start your
vehicle, and the bad grounding could damage
the electrical systems.

You could be injured if the vehicles roll. Set the parking brake firmly
on each vehicle. Put an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL (N). If you have a
four-wheel-drive vehicle, be sure the transfer case is not in NEUTRAL
(N).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This
will avoid sparks and help save both batteries.
And it could save your radio!
NOTICE:
If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
A CAUTION:
Using a match near a battery can cause battery gas to explode.
People have been hurt doing this, and some have been blinded.
Use
a flashlight if you need more light.
Be sure the batteries have enough
water. You don’t need to add
water to the Delco Freedom@ battery (or batteries) installed in
every new
GM vehicle. But if a battery has filler caps, be sure
the right amount of fluid is there.
If it is low, add water to take
care
of that first. If you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you. Don’t get
it on
you.
ff you accidentally get it in your eyes or on your skin, flush
the place with water and get medical help immediately.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do,
you could get a shock. The vehicles could be damaged, too.
Before you connect the cables, here are some basic things you should
know. Positive
(+) will go to positive (+) and negative (-) will go to
negative
(-) or a metal engine part. Don’t connect (+) to (-) or you’ll
get
a short that would damage the battery and maybe other parts, too.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades’’ in the Index.
If
you get the overheat warning with no sign of steam, try this for a minute
or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan speed and open the
window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the
highest gear while driving
- AUTOMATIC OVERDRIVE (@) or
DRIVE
(3) for automatic transmissions.
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If
the warning continues, pull over, stop, and park your vehicle right away.
If there’s still no sign of steam, push the accelerator until the engine speed is
about twice as fast as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now see
if the warning stops.
But then, if
you still have the warning, turn ofSthe engine and get everyone
out of the vehicle until it cools down.
You may decide not to lift the hood but to get service help right away.

Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid level is when the
engine
oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See "Scheduled Maintenance Services''
in the
Index.
How to Check
Because this operation can be a little difficult, you may choose to have this
done at your
GM dealer Service Department.
If you do
it yourself, be sure to follow all the instructions here, or you could
get
a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your transmission. Too
much can mean that some of the fluid could come out and fall on
hot engine parts or exhaust system parts, starting a fire. Be \
sure
to get an accurate reading if you check your transmission fluid.

How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of transmission
fluid
to use. See “Recommended Fluids and Lubricants” in the Index.
Add fluid only after checking the transmission fluid
HOT. (A COLD check
is used
only as a reference.) If the fluid level is low, add only enough of the
proper fluid to bring the level up
to the HOT area for a hot check. It doesn’t
take much fluid, generally less than a
int. Don ’t overfill. We recommend
you use only fluid labeled DEXRON
-111, because fluid with that label is
made especially for your automatic transmission. Damage caused by fluid
other than DEXRON@-I11 is not covered by your
new vehicle warranty.

0 After adding fluid, recheck the fluid level as described under “How to
Check.”
0 When the correct fluid level is obtained, push the dipstick back in all
the way; then flip the handle down
to lock the dipstick in place.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is changed. However,
the fluid
in your manual transmission doesn’t require changing.
How to Check
Because this operation can be a little difficult, you may choose to have this.
done at your
GM dealer Service Department.
If you do it yourself, be sure to follow all the instructions here, or you could
get a false reading.
NOTICE:
Too much or too little fluid can damage your transmission. Too
much can mean that some of the fluid could come out and fall on
hot engine parts or exhaust system parts, starting a fire.
Be sure
to get an accurate reading if you check your transmission fluid.
Check the fluid level only when your engine is off, the vehicle is parked on
a level place and the transmission is cool enough for you to rest your fingers
on the transmission case.
