2004 Chrysler Sebring wont start….. Pleas Help!

I have a 2004 Chrysler Sebring. While driving on the highway a transmission line burst suddenly and all of my trasmission fluid leaked out. My car has not started since then. I took it back to the place I purchased it from 6 weeks ago. He said they fix the transmisson line but couldnt figure out why the car would not start, though this is a place where they take apart and put together cars daily. What could the issue be?
