Sssoooo I was doing a burn out.... Automatic transmission, in a '62 chevy. The tranny shifted into 2nd and then made a loud noise and the engine revved up because the power wasn't being put to the wheels any more. When I put the car in park there was a grinding sound so I took it back out. I shut it off and we rolled it, and it popped and cracked in the rear end. I started it back up and put it in drive and it had a delayed shift by about 10 seconds. It drove fine when in gear, but made a pop and went out of gear again. Now when I put it in park it doesn't grind, but it doesn't keep the car from rolling. The scary part is, dad doesn't know and he is probably going to murder me. I just want to know if it could just be in the rear end? What do you all think?
