What does it mean when my O/D light is flashing on and off?

I have a 2003 ford e350 super duty van and my van started to rev high and my O/D light is flashing and won't shift out of 2ed and it's spitting fluid out the top of the transmission.

  • I can rule out a flat tire as the cause. I would consider the transmission has a major and expensive problem. Have it checked. Could be a sensor in the transmission sending an OBD code to the computer. Make sure the transmission fluid is at the proper level (check with engine running, in Park, on level ground).

  • Wow! Spitting Cobra's and spitting tranny fluid. Did someone overfill the tranny? That's the usual culprit for fluid loss from the top side or vent tube. Under filling the tranny is what most grease monkeys do. They forget that most tranny's have to be filled with the engine running so they leave out two or three quarts.

  • A flashing O/D light means there is a fault in the transmission control system. Your vehicle is now in fail safe mode. Go to the dealer and they will use the factory scan tool to read the transmission codes and read the transmission data to determine which sensor or solenoid is the problem.

    Going to a tranny shop you're likely to be told you need a rebuilt transmission rather then them diagnosing it properly.

  • The O/D light is the "Check Engine Light" of the transmission on older vehicles.  You need a scanner that can check transmission trouble codes to find out what is wrong with the transmission.  There is likely a bad shift solenoid or the fluid pressure has dropped caused by the fluid leak.  See a transmission garage.
