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