From the first drive I noticed a slight vibration in the shift handle when in third gear. The other gears didn't seem to have the same although some could be felt in those too. As I have added miles either the vibration has receded or I have gotten used to it. I now have about 1200 miles on my roadster and a noise starting to develop that sounds like a loose bearing. It gets louder as the transmission heats up and is most noticeable in fifth gear with very little power applied. It has a rattle sound that radiates along the drive line. I suspect a bearing that doesn't have proper preload. I don't think the two are related but though I would get some opinions. I have the mid-shift installed and of course cut the lower mounting flange off the tail shaft. Both of these actions probably voided a warranty as well as the sale date of 2013 so I think I will have to remedy the problem myself.
