and read the lower level. The
fluid level must be in the COLD
area, below the cross-hatched
area, for a cold check or in the
HOT or cross-hatched area for a
hot check. Be sure to keep the
dipstick pointed down to get an
accurate reading.
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 Automatic
Transmission Fluid
Refer to the Maintenance
Schedule to determine what kind
of transmission fluid to use. See
Recommended Fluids and
Lubricants on page 11 6.
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 0.5 L
(1 pt). Do not overfill.
