Basically as I normally accelerate onto the highway as I start going threw fourth vibration starts then as I get into fifth about 70 mph it's highly noticeable. Feel it in the seat and steering wheel Then it literally all of a sudden stops. Never the same point either. Sometimes almost immediately. and sometime a mile down the road. But all of a sudden. Unless you have a hold of the shifter. It always has a decent vibration. But it's also raining here. And I just got pretty good wheel hop on soaked pavement. Etc it
