I have a clutch "shudder". It doesn't really translate to motion issues, I can just hear the clutch shudder. Especially at very low RPM shifts / pulling into garage etc.
Since my car was in for one last "pre-warranty-expiration" tune-up, I put it down as an issue, but the service tech wrote it off as normal for our cars (he had a pretty lengthy explanation). It doesn't seem to cause any issues actually moving (the car still moves smoothly).
