Very violent shifting from park to reverse or drive

Mine does it quite frequently. More often on slight incline but happens on level surface as well. Still bugs me although dealer never found anything wrong.

Hi.
I had the same problem some years back on a Ford Explorer.
Exactly as you describe. Make sure the revs are at total idle and the problem will be less severe.
It turned out it was a sticky solenoid valve in the gearbox. This was changed under warranty and fixed the problem immediately.
Get your dealer to take a look at it.......

Mine does the same mostly when on a incline of any degree
