Hot Check Procedure The fluid must be hot to ensure an accurate check. The fluid level rises as temperature increases. 1. Operate the transmission in DRIVE (D) range until the normal operating temperature of 160°F (71°C) to 200°F (93°C) is reached. Consistency of Readings Always check the fluid level at least twice using the procedures described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If inconsistent readings persist, check the transmission breather to be sure it is clean and unclogged. If readings are still inconsistent, contact your dealer. 2. Pull out the dipstick and wipe it with a clean rag or paper towel. 3. Push it back in all the way, wait three seconds and then pull it back out again. Repeat the check procedure to verify the reading. 4. Safe operating level is within the HOT RUN band on the dipstick. The width of the HOT RUN band represents approximately 1.06 quart (1 .O liter) of fluid at normal operating temperature. How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See Part D: Recommended Fluids and Lubricants onpage 6- 18. Add fluid only after checking the transmission fluid while it is 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 overfill. 5. If the fluid level is not within the HOT RUN band, add or drain fluid as necessary to bring the fluid level to within the HOT RUN band. 6. If the fluid level is in the acceptable range, push the dipstick back in all the way. 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. When the correct fluid level is obtained, push the dipstick back in all the way. 5-30

Hot Check Procedure
The fluid must
be
hot to ensure
an accurate check. The
fluid level rises as temperature increases.
1.
2.
3.
4.
5.
6.
Operate the transmission in DRIVE
(D) range until
the normal operating temperature of
160°F
(71°C)
to
200°F
(93°C)
is reached.
Pull out the dipstick and
wipe it with a clean rag or
paper towel.
Push it back in all the way,
wait three seconds
and
then
pull it back
out again. Repeat the check
procedure to verify the reading.
Safe operating level is within the HOT RUN
band
on the dipstick. The width of the HOT
RUN
band
represents approximately
1.06
quart
(1
.O
liter)
of fluid at normal operating temperature.
If
the fluid level is not within the HOT RUN
band,
add or drain fluid as necessary to bring
the fluid
level to within the
HOT
RUN band.
If
the fluid level is in the acceptable range, push
the
dipstick back in all the
way.
Consistency
of
Readings
Always
check the fluid level at least twice using the
procedures described previously.
Consistency
(repeatable readings) is important
to
maintaining proper
fluid level. If inconsistent readings persist, check
the
transmission breather to be
sure it is clean and
unclogged.
If
readings are still inconsistent,
contact
your
dealer.
How
to
Add
Fluid
Refer
to
the Maintenance
Schedule
to
determine
what
kind of transmission fluid to
use.
See
Part
D:
Recommended Fluids and Lubricants
on
page
6-
18.
Add fluid only after checking the transmission fluid while
it is 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
overfill.
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
When the correct fluid level is obtained,
push
the
described under
How
to
Check.
dipstick back in all
the
way.
