Same crap happened to me a couple of months ago, that's If this Is the same problem that I had. I forgot the name of It but, It's a little sensor under where the break and gas pedal Is. what happened to me was, that sensor Im talking about, It controls the break lights as well as the ability to put It into drive. there was a wire that got pulled out that sensor that controls It to go into drive, reverse, neutral and such...the sensor would be located If you follow your break pedal all the way up into the dash...check It for any loose wires. If It is that, you may want to look at a diagram of It to get a better understanding of It, which you can find online somehow. that's all I know about It...
