When I jab the throttle in park it vibrates terribly and sounds like somethings grinding, also most like a shot bearing somethings out of balance and now it makes a rattling sound at idle . It sounds like it's coming from the trans. I'm pretty sure it's either the flexplate or converter. The car drives completely normal....... no slippage or hard shifting. I hope/ pretty sure it's not my engine.
Sorry about the quality, it's the only camera I have.
