I was driving my 2001 ford taurus, came to a traffic light. when time to take off car would not go. It will start up find but when i put it in gear you can't feel it shifting and it will not not move, in reverse either. When I looked under the hood I saw a fluid on top of the stearing power fluid top and underneath the car fluid was leaking. Someone said it looks like transmission fluid. We checked resevoir for fluid there was fluid in there. Do you know what it can be
