I am drywalling my unheated, partially-below grade exterior garage. A four-foot tall concrete wall runs along the parts of the garage that are below-grade.
Above the concrete walls are 2×6 wood framed walls. The wood is anchored to the concrete and separated with a sill gasket. There is a 1/2 inch ledge so the drywall will be flush with the concrete.
What can I do to transition between the drywall and the cement? I don't want a gap, and I suspect the drywall shouldn't be in direct contact with the concrete.

In my last house a daylight basement the original sheetrock was glued to the cement walls with liquid nails that worked very well. I did pull it all out and add furring for electrical spaces. (I don't like exposed conduit and surface boxes in a room that became my man land). If you are worried about cracking at the sill add a accent trim over the gap.
