TRANSMISSION FLUID

Checking and adding automatic transmission fluid
Follow the scheduled service intervals outlined in the "Service Guide."
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and/or dipstick handle
and also in the Lubricant specifications section in the Capacities and
specifications chapter.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Do not drive the vehicle if the fluid
level is below the bottom (cold)
notch on the dipstick and outside
temperatures are above 10°C (50°F)
(see figure to the right).
Your transmission does not use up fluid. However, it is recommended
that you check the transmission fluid at least twice a year. The fluid level
should be checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Transmission fluid should be checked at normal operating temperatures
66°C-77°C (150°F-170°F) on a level surface. The normal operating
temperature can be reached after approximately 32 km (20 miles) of
driving.
The transmission fluid should be in
this range if at normal operating
temperature (66°C-77°C
[150°F-170°F]) (see figure to the
right).
The transmission fluid should be in
this range if at room temperature
(10°C-35°C [50°F-95°F]) (see figure
to the right).
