Yellow area(warning)—the
transmission fluid is higher than
normal operating temperature. This
can be caused by special operation
conditions (i.e. snowplowing, towing
or off road use). Refer toSpecial
Operating Conditionsin the
Scheduled Maintenance Guidefor
instructions. Operating the
transmission for extended periods of
time with the gauge in the yellow
area may cause internal transmission damage.
Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.
Red area(over temperature)—
the transmission fluid is overheating.
Stop the vehicle to allow the
temperature to return to normal
range.
If the gauge is operating in the Yellow or Red area, stop the vehicle and
verify the airflow is not restricted such as snow or debris blocking airflow
through the grill. If the gauge continues to show high temperatures, see
your Ford dealer.
