Hi.,
I had a very minor clutch shudder or shake or vibration that would occur
when starting out in first.  This would happen about 50% of the time,
especially if the rpms were on the low side.  I changed the clutch slave
cylinder ever thought there was no blantant reason to do so.
In fact, I changed it to see if that would facilitate shifting.  Well, the
shifting is a little easier, but the shudder is gone.
