I have a 2007 3500 5.9L with a 48re transmission. When I put the truck in park it rolls. The indicator is on Park. I have no other problems with it. Has anyone ever heard of this happening? We have checked the adjustment on the shifter. I guess tomorrow (Wednesday) morning we are going to drop the pan and service the tranny and see if there is anything obvious that could be causing this problem. If you have had experience with this or just some advice, I am all ears! Thanks!
