I've been getting a vibration/shutter while accelerating. It’s directly related to RPMs. Only happens between 2 and 3k. (2200 and 2700 to be exact) The vibration is more pronounced when turning right. Torque related, more pronounced in 1st, 2nd and 3rd, but It’s felt in all gears, except 5th. I do get a slight vibration when cruising at 70, in 5th, RPMs at 2100. Any ideas?
