hi all, when im driving on either street or highway, accelerating fast or slow, i get this vibration coming from the shifter in 3rd gear. i think somethings wrong so i put it out of gear and then back in and it still keeps doing it as im accelerating. any of you guys have this problem? or is it even a problem at all? this only happens in 3rd so far. i have a 2.3l 06 mz3
