727 ticking in park?

I got "Dragged" on a FB page once over someone having this issue, or shall I say they thought they had.... My suggestion was in relation to the parking Pawl, and if it had the incorrect rod '904 instead of a 727' and/or if the adjustment was incorrect. As in it never really gets completely in park.... just close enough to catch alittle on flat ground. The point I was making is that you can actually engage the parking pawl and still be enough in reverse that it will direct fluid flow.... thus making a horrible sound and allowing the car to roll as well as send power for reverse. If the car is on jacks you can safely inspect this....
