I have a 97 Subaru Impreza 2 door (AWD, manual transmission) with about 165k miles on it. The shifter moves side to side even when the car is in gear, as though it is coming loose. I am noticing no ill effects on the actual transmission (the car stays in gear and the transmission is otherwise working). It is, however, becoming increasingly dificult to tell whether I am shifiting into 1st or 3rd gear because the shifter is so loose. Is this something I can tighten without considerable invasion into the car, or should I seek a mechanic for help? If I need help, how much can I expect to pay to get this fiexd?
