3. Check both sides of the dipstick, and read the lower
level. The fluid 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 one pint
(0.5 L). Don ’t ove@ZZ.
NOTICE:
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-111
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.

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 dealership
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.
Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom of
3. If the fluid level is good, install the plug and be sure

it
is fully seated. If the fluid level is low, add more
fluid as described
in the next steps.
