So the dealer has come back and found "nothing wrong with the clutch"....they re-bled it and it has been fine since I've had it back from them, sometimes it returns quite hard and fast but it hasn't gotten stuck anywhere...so I think there's still something wrong with it but unlikely it's going to be covered under the stat warranty.
The other thing they picked up when I told them about the clunk in the rear...the diff is stuffed...so it's currently in getting re-built and should have her back on Friday....it appears the previous owner didn't treat her very well....
