2016 GT 6 speed manual. I kept my hand on the shifter (lightly) the other day and realized there is a vibration in the shifter in 4th only. It is slight, and not felt in my butt or feet, only in my hand. Does anyone elses do this? Is it something to worry about? Maybe the gears are cut different?

 

I don't know if I want to see it, nor do I have an answer, but it sounds impressive that you can shift with yer butt and yer feet.

 

NOT feel it.
