Thought of that too, Rob... I shifted light and hard, fast and slow, with both knobs. No difference. And made SURE the clutch was always fully depressed (like I said, I was hardly ever in a hurry). I even showed the dealer mechanic and he couldn't wrap his head around it, either.

Although this was the same guy that was SUPER granny-shifting my car to show me it had no issues at all, until he went into second with a CRRRUNNNCHGRRRIIINNNDDD... and he STILL hesitated a few seconds before admitting there might be a problem.
