Mine has gotten worse, took it back last Friday for another drive with the dealer, and they do agree something amiss..
It goes in tomorrow am, they want to start by doing an oil analysis.. pretty sure they will find plenty of metal. I'll report back once I know more.
Fyi, mine also has what sounds like a rattle in the throwout bearing, occurs when you load/unload the drivetrain via the clutch. I can duplicate it easily just rolling at a few mph, very noticeable rattle. I tend to think my transsmission issues may be clutch related, although I haven't had the sticking clutch some have reported.
In my original post I was wondering if the shifter it self might be the issue, replaced it with an MGW, didn't fix the problem. (really didn't think it would) The MGW is excellent, just as many have reported.
