hi i have a lancer 1.5 2001 gdx this comes with a cvt auto box is it possible that vibration at about 80kph could be caused by the box the vibration is through the bod of the car not the steering wheel it only starts when i hit 80 and accelerate if i lift off or coast it stops just a little bit of gas and vibration is back i can coast down hill at 100 no problem also do get some vibration turning left at slower speeds none at all turning right at slower speeds any ideas thanks all ps could the cvt oil cause this problem ie need changing 60000k oil not changed yet
