Neutral safety switch

I moved the shifter around and when it was in drive it started right up like normal. On the way home we stopped at the store and I left the car running. I went to put it in park and it was slipping and rolling down the slight grade in the parking spot, making a clicking noise like it was trying to "catch". Any ideas what this might be. It's making me very wary of its reliability.

thanks in advance for your help.

Not starting in park could mean your neutral safety switch. Try starting in neutral. Regarding the "catching", my tranny does the same thing. It is the parking pawl trying to engage the notch that it goes into, to lock the transmission up. To prevent further wear to this part which is inside the tranny, always use the parking brake. If it is out of adjustment, it is really easy to fix. You want your parking brake to work correctly as a matter of safety. This way you don't have 3,800 lbs. of Mercedes being held by just the tranny when it is parked.
