I might also recommend changing your clutch line and fluid as well...Most people forget about those.
Jus got a brand new clutch. Newbie to it all. Im thinkin short shift will help an tranny fluid change. Im gonna take it to dealership since it under wArranty make them do it for free. Its weird bcuz i never have any problemin any other gear beside 3rd when im ripping. so maybe its jus me i dunno? Damn awd car gott b gentle on the rex
