Transmission issues

I slid into ditch the other night, did not bottom out but barely nudged a street sign pole. Immediately I had no reverse, no overdrive, I do have first, second and D. But it only goes thirty mph tops, and revs up to about 3,500 rpm. And that is that. It is almost like it is stuck in a gear, there is a slight almost like marbles rolling around sound when I try to put it in reverse.
