Get it checked out. You have an electrical problem. Most likely a short. Overdrive is basically a "Higher Gear" allowing the wheels to spin faster than the engine, which increases fuel effeciency. If this is out, you will only get to use the next lowest gear. I have a 6 speed automatic. Which means, I could only use up to fifth. If yours is a 5 speed auto, then you can only use up to fourth gear.
If you are on a highway maintaining over 45 mph. OK, but If vehicle continually shifts in and out of overdrive you are better off leaving it in 3rd
