Has anyone else experienced a very abrupt, loud thunk when shifting from R into P? It doesn't happen to me every time, and I'm beginning to think I just need to pause a moment and make sure I've come to a complete stop after backing into the garage, but all the same it's very disconcerting to hear and feel such a loud clunk (I can feel it through the shift lever) when I put it in P. Interestingly enough, it only happens when I back into the garage, and not when I back out of a parking spot. Might have to do with the relative speeds with which I execute those two maneuvers, with backing out of a parking being a slower, more cautious maneuver than backing into my empty garage.
