My van was parked for a week or so. I went out to run errands. I put the van in reverse and it rolled backward from the slope of the driveway but wasn't in gear. I put it into drive and it rolled backward from the slope of the driveway but wasn't in gear. I put it in park and back into drive and drove up the driveway. I put it in reverse and backed out and went about my business. It was fine from then on. I have no idea what was up the first time. Any opinions?
