Hi, I've noticed two things that I think are related. On semi level ground I can Rev the engine a few times high and the car will roll back (towards decline) while it is in park.. it only rolls less than an inch but you can feel it slip out of park
Today I parked it on an incline and it slipped out of park rolled an few inches and then stopped. I was fine after that.
I know there are brake bands u can adjust. Will this help?
