How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Recommended
Fluids and Lubricants on page 7-12.
A. WARM Range
B. HOT Range
Using a funnel, add fluid down the transmission dipstick
tube only after checking the transmission fluid while it is
warm or 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 middle of the WARM (A) or
HOT (B) range depending on the ambient temperature
and prior driving conditions. Refer to "How to Check
Automatic Transmission Fluid", earlier in this section
for instructions on driving to achieve warm or hot
transmission fluid. It does not take much fluid, generally
less than 0.5 L (one pint). Do not overfill.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7-12.
•
After adding fluid, recheck the fluid level as described
under "How to Check Automatic Transmission Fluid,"
earlier in this section.
•
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.
