How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Recommended
Fluids and Lubricants on page 6-12.
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 does not take much fluid, generally less than one pint
(0.5 L). Do not overfill.
Notice: Use of automatic transmission fluid labeled
other than DEXRON
® -III, Approved for the
H-Specification, may damage your vehicle, and the
damages may not be covered by your warranty.

DEXRON

described under “How to Check,” earlier in
this section.
• When the correct fluid level is obtained, push the

down to lock the dipstick in place.
