what could be causing my car to make whinning noise at 20-30 mph on 1996 Geo Metro

when it does this there is a jerk feeling.. also my reverse went out.. it sometimes works when you put it allthe way down and back up a couple of times.. use a computer it states its the shifter with the problem.. but dont know what to do to fix it
