2k dodge stratus sudden multiple errors

I am obviously very new to the forums, and am requesting help with my stratus. I ran over something earlier today and the car seemed ok. Then on the freeway the spedometer first went out, then the check engine light came on. Before long the low gas light came on, then the oil light. Then the car would not shift higher than 2nd or 3rd gear (automatic- and this happned once I had already exited the freeway and subsequently the car downshifted) I pulled into a gas station, put gas in and checked trans. and oil fluid levels. They were ok. I drove slowly home and the car shut off on the way, but immediately turned back on and did make it home.

Could this be caused by the computer? I know woefully little about cars, but this seems far too many errors at once. I will be taking it to the mechanic tomorrow, but I wanted some idea of what to expect. Is there anything I can do on my end?

I appreciate any advice or guesses as to what this could be.

Note -the spedometer stopped, then started again and now is not working -all in the span of 20 minutes if that helps at all.

sounds like what ever you hit must have hit one of your sensors. check out this link http://www.stratusphere.us/forums/index.php?showtopic=180

Thanks eXcelon for the link -I read the thread and it does sound like my problem. I have it at the shop now. It seemed to work fine once I got it there (go figure) but he's gonna check it out. Hopefully it's just a loose connection.
