Will it roll in park? Have you checked the linkage to make sure it is still attached?
As far as the issue, if the trans fluid is still full and clean and doesn't smell burned, it sounds like an electrical issue. My first guess, if nothing works, is the trans control module (TCM). If it doesn't shift from 2nd gear (stays there all the time), then it is in limp mode. That is to get you home or to a shop. You need to have the TCM scanned to see if any codes are stored.
Just fyi, it is normal for the car to roll in neutral.
