Automatic Transmission Fluid

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
overheated transmission. This vehicle is not
equipped with a transmission fluid level
dipstick. There is a special procedure for
checking and changing the transmission fluid
in these vehicles. Because this procedure is
difficult, this should be done at the dealer.
Contact the dealer for additional
information.
Caution
Use of the incorrect automatic
transmission fluid may damage the
vehicle, and the damage may not be
covered by the vehicle warranty. Always
use the correct automatic transmission
fluid. See Recommended Fluids and
Lubricants 0 365.
Change the fluid and filter at the scheduled
maintenance intervals listed in Maintenance
Schedule 0 359. Be sure to use the
transmission fluid listed in Recommended
Fluids and Lubricants 0 365.
