2001 Chevy Tracker 4 cyl Two Wheel Drive Automatic 150000 miles
When I shift to drive or reverse, the car lurches a little accompanied by a sort of moan sound. Once in gear its fine and drives well. I'm just concerned that this could be the beginning of a bigger problem. I just changed the transmission fluid and it was pretty dark, like engine oil. I didn't replace the filter as it had a drain plug.
