Instrument Cluster Transmission fluid temperature gauge: 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. 16
