96 Pontiac Grand AM wont turn over.

I have a 96 Pontiac Grand AM SE V6. My transmission fluid was leaking and I was putting more in. I was running through the gears and it wouldn't go back into park. I turned the car off and now it won't turn over. I cant get it to go back into park either. I need my car fixed asap and I dont know what to do. HELP!!!

Try starting the car in neutral as it should start there. The car is designed to only start in park and neutral.
