The overdrive light to flash on 2005 Ford Expedition is caused by either the sensor problem or the electronic pressure control problem for the tranny.

The light will flash if the vehicle senses that you should be in overdrive (based on speed) but aren't. There should be a button on the end of your gearshift lever to turn overdrive back on. The only time you should turn that off is, for example, if you are pulling a trailer in the mountains. Turn OD back on and the light will stop flashing. If it doesn't stop then there is a problem with the transmission going into overdrive.
So first I do not have this vehicle. In general when you see overdrive light flash or stay on, it means overdrive has been turned on. In most vehicles the overdrive button is either on the gear shifter or on the stiring colum. If you dong want or need overdrive on then just press the button. If your light stays on, then it could be something different and not so simple.

something is wrong in the transmission. It will have to be diagnosed. You probably have a bad shift solenoid in the tranny.
