Title says it all really, but I have a recently acquired 2012 1500/5.3L 6 speed trans. Silverado. Yesterday I was creeping along a road, coasted to a stop on a slight hill. Immediately the truck begins to roll backwards (did not apply brake as I was curious what would happen) while still in drive and dies. I'm use to my old silverado (97) where it would stay engaged and prevent backwards movement on hillsides when in drive without having to apply the brake.
Is this normal or is something wrong with my truck?
