I recently slid into a pretty bad snow filled ditch.Did minor damage to the left side of the front end of car. (Which I think the trans. is on the right side) The car's automatic transmission will not engage into any gear. The shifter moves smoothly as usual, although all gears, including reverse, all seem to be just stuck in neutral. There is aren't any unusual noises or****** in the car. It just seems to always be in neutral. Is there a safety shutoff in case the fluid has leaked too low, or possibly a wiring harness that transfers information that would not allow the car to go in gear? Please help with this. Thank you
