This is a strange couple of question really... but I was just curious. If you have an automatic and you put your car in first, then second, then into drive... will it hurt it to do this on a constant basis? Just curious. Also, I was curious if you put your car in reverse, then put it into neutral(perhaps when backing down a hill), then put it in drive, is that better than just shifting neutral to reverse real fast? Odd questions I know, but something I've been pondering. Thanks for everyones input.
