Maintenance and Specifications
5. Remove the dipstick, wiping it clean with a clean, dry, lint-free rag. If
necessary, refer to Identifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect
the fluid level. The fluid should read
within the hot range on the dipstick
if at normal operating temperature
(140°F-158°F [60°C-70°C]).

Checking automatic transmission fluid at cool temperature

(59°F-77°F [15°C-25°C])
If a fluid check is necessary at a low
fluid temperature (59°F-77°F
[15°C-25°C]), perform the check
using the cold range on the dipstick.
However, the fluid must be
re-checked at the proper fluid temperature.

Low fluid level

Do not drive the vehicle if the fluid
level does not show at all on the
dipstick.
Driving the vehicle with less than
the recommended fluid level may result in transmission failure. An under
fill condition of transmission fluid may cause shift and/or engagement
concerns and/or possible damage to the transmission.

High fluid level

Fluid levels above the normal
operating range may result in
transmission failure. An overfill
condition of transmission fluid may
cause shift and/or engagement
concerns and/or possible damage to
the transmission.
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 and also in the
Maintenance product specifications and capacities section in this
chapter.
