I'm not sure how else to describe it. When I put it in reverse to back out of the driveway 1st thing in the morning, it seems to hiccup a little the whole way down the driveway. I can't really tell if its the engine stuttering or if the transmission is slipping. This happens when idleing, my foot isn't even on the gas. It also only seems to happen in reverse, which makes me think something is up with the transmission. Any ideas?
