Mine has a shudder that feels more like a control system oscillating than the
mechanicals.  In fact, I posted about it shortly after I picked it up, but
got no nibbles or afirmation.

It happens in mine when I shift quickly (not overly quickly - just not
leisurely) at medium to high RPM.  Upon thinking about it, it does seem to
happen most on a 3-4 or 4-5 shift.  When I put my foot back in it after the
shift, I get this kind of slow soft shudder/surge at about 5-10Hz throughout
the car for about 1-2 seconds.  It almost feels like a turbo coming off the
wastegate and oscillating a bit.  I assume that something is trying to
control the RPM drop during the shift, and not getting out of my way fast
enough...

I guess I'll have the dealer look at it when I put it in for the scheduled
service in another 1500 miles or so.
