I have not been parking on hills. This is happening in flat/level parking lots. My truck is going into the shop next week for oil change/tire rotate and I will have them look at it then. It seems as though the longer the truck sits the harder it is to shift out of Park into gear. Reverse to Drive or any other combo is a smooth shift. I will start to use the parking brake and see if that makes a difference.

I hate going into dealership service departments clueless. I am a petite blonde female and the service advisors assume that means dumb. One even told me that I would have to pay for an alignment on my truck at 8000 miles!

Thanks for your help!
