Was riding in my buddy's GT today noticed a whine while we was driving down the road, sounded like he had a blower also a slight rattle of some sort, he didn't pay it no mind, next thing we know the car bucked and there was a loud pop but the car didnt stop we pulled over and the car kept running just making a chatting noise but no whine until it was in gear moving. Drove further down the road on the way to get it checked out and it clunked again pulled over and the car shut itself off. Car will not go into ANY gear now. What could have possibly happened? Don't think it's the bottom end cuz the car can be pushed without jolting and locking up??
