RE: park not holding

The indicator (not the technical term, I know) slides past P, doesn't it? Is the shifter loose?

Trannies are not my strong suit, but it sounds like the parking pawl in the trans has broken or worn so that it does not hold.

RE: park not holding

Yes that is what it sounds like the pin or pawl is worn or broke to were when you put it in park it will not hold at all!! Looks like the tranni needs to get serviced for this part!!
