My '05 GT with 5-speed manual is very "clunky" when shifting into all gears. I'm leaning towards the linkage bushings being the issue (start with the cheapest fix first, right!?!) My question is how much (if any) does an aftermarket shifter smooth up shifting? If I've got to replace it, I might as well put a short-throw shifter in it. I've searched the forum, but only found references to clutch and throw-out bearing causing shifting issues, but I don't think this is the problem.
