automatic transmission fluid CHEVROLET ASTRO CARGO VAN 1995 2.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more
on this. Things that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, and brake
adjustment. Each of these is covered in this manual, and the Index will help
you find them quickly. If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch nuts and bolts are tight.

If the air cleaner is off, a backfire can cause a damaging engine
fire. And, dirt can easily get into your engine, which will damage
it. Always have the air cleaner in place when you’re driving.
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.
Wait at least
30 minutes before checking the transmission fluid level if you
have been driving:
When outside temperatures are above 90°F (32” C).
0 At high speed for quite a while.
0 In heavy traffic - especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which is 180°F to
200°F (82°C to 93°C).

level must be in the COLD area for a cold check or in the
HOT area or
cross-hatched area for a hot check.
4. If the fluid level is in the acceptable range, push the dipstick back in all
the way; then flip the handle down to lock the dipstick in place.
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 overjill. We recommend
you use only fluid labeled DEXRON
8 -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.
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.
