I was looking into the HD CSC last night and saw that ZSpeed recommended replacing the CMC at the same time. Did you do this? They state that a dirty CMC can affect their CSC.
There were also posts on this forum where Joe, from Zspeed, recommended replacing the HD CSC when pulling the trans, so it does not sound like it is infallible.
Does the clutch pedal return to the top after you release it?
You could try bleeding the clutch just in case.
