Transmission fluid temperature gauge (automatic transmission
only): If the gauge is in the:
White area (normal) - the
transmission fluid is within the
normal operating temperature
(between “H” and “C”).
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 to Special
Operating Conditions in the
scheduled maintenance guide for
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.
