7. Remove the dipstick and inspect the fluid level. The fluid should be in
the crosshatch zone for normal operating temperature.
Low fluid level
Do not drive the vehicle if the fluid
level is at the bottom of the dipstick
and the outside temperatures are
above 50° F (10° C).
Correct fluid level
The transmission fluid should be checked at normal operating
temperatures 150° F-170° F (66° C-77° C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles (30
km) of driving.
The transmission fluid should be in
the crosshatch zone if at normal
operating temperature (150° F-170°
F [66° C-77° C]).
High fluid level
Fluid levels above the crosshatch
zone may result in transaxle failure.
An overfill condition of transmission
fluid may cause shift and/or
engagement concerns and/or
possible damage.
High fluid levels can be caused by an overheating condition.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick blade and also in the
Lubricant specifications
section in this chapter.
Use of a non-approved automatic transmission fluid may cause
internal transaxle component damage.
If necessary, add fluid in 1/2 pint (250 ml) increments through the filler
tube until the level is correct.
