So, I hop in my 96 Civi Caprice to leave work. I back up approximately 3/4ths of a car length and there's a bang and the car jolts to a stop (tires even squawked.) I'm looking around thinking I hit something or somebody put something under my car that I ran over. I don't see anything, pull forward, still nothing. I put the car in reverse and all I hear is a tinny spinning rattle sound. Put it in drive and it pulls forward again. Put it in reverse, tinny spinning rattle sound. Soooooo...am I looking at a trans replacement?
