Is this your 94 with the 3.4 V6? Check to see if any wires got disconnected down along the front of the engine. It sounds like something wiring is out of whack. Your fans might not be turning on which leads to the overheat and the trans coolant as well. It reallys sounds like you hit something that might have dislodged some wiring.
