Not too sure if I have the same problem or if I have any problems at all but....
Up-shift from 1-2 and particularly from 2-3 feels as if I'm trying to push the stick through a bowl of large pebbles (lot's of intermittent resistance). When I up-shift on the higher gears (4-5) I only feel a single "thunk".
This all happens before I engage the clutch bellow 3000RPM.
It also spitted me out once from 1st gear into neutral. I'm leaning to think that I did not got the stick all the way in but it's still making me nervous.
