FORD 2002 Mustang v.1 - Manual (Page 239)

Low fluid level
Do not drive the
vehicle if the fluid level
is at the bottom of the
dipstick and the ambient temperature is above 10°C
(50°F).
Correct fluid level
The transmission fluid should be checked at normal
operating temperature 66°C-77°C (150°F-170°F) on
a level surface. The normal operating temperature
can be reached after approximately 30 km
(20 miles) of driving.
You can check the fluid without driving if the
ambient temperature is above 10°C (50°F). However,
if fluid is added at this time, an overfill condition
could result when the vehicle reaches normal
operating temperature.
The transmission fluid
should be in this range
if at normal operating
temperature (66°C-77°C [150°F-170°F]).
The transmission fluid
should be in this range
if at ambient
temperature (10°C-35°C [50°F-95°F]).
High fluid level
Fluid levels above the
safe range may result
in transmission 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.
