My 87 560SL has had a serious clunk in the drivetrain whenever I shift from neutral to drive or reverse. Nothing happens for about a second, then it bangs hard. Also, when the transmission downshifts as the car is slowing down, I get the same delay and clunk when I step on the gas. There is no driveshaft vibration or any other symptoms that I'm aware of.
Anybody run into this before?
