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 711.
Using a funnel, add fluid down the transmission dipstick
tube 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 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 711.
.
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.

When to Check and Change Automatic
Transmission Fluid
It is usually not necessary to check the transmission
fluid level. The only reason for fluid loss is a
transmission leak or overheating the transmission. If a
small leak is suspected, use the following procedures to
check the fluid level. However, if there is a large leak,
then it may be necessary to have the vehicle towed to a
dealer/retailer service department and have it repaired
before driving the vehicle further.
Change the fluid and filter at the intervals listed in
Scheduled Maintenance
on page 73
, and be sure to
use the transmission fluid listed in Recommended
Fluids and Lubricants on page 711.
How to Check Automatic Transmission
Fluid
Because this operation can be difficult, it is
recommended to have this check done at the dealer/
retailer service department, which can monitor the
transmission temperature. The transmission fluid level
increases with temperature. To obtain a highly accurate
fluid level check, the transmission temperature must be
measured.
