I'm not sure this is my SE5 just settling in after the initial running in period so this could now be a normal characteristic but the change up has somewhat of a thump to it. I'm fairly certain is was smoother previously. From what I understand of the SE5 system, it drops the revs when throwing the gears in so that the transition is smooth, and does this regardless of where the throttle is positioned. This should mean smooth syncing but at present there is a definite jolt as it moves through each gear. Downshifting is fine.
