Bleeding Spec 3.
Um...I can only think that you should take everything out, put in a new master cylinder, the new slave, bleed it (at least 3 times)...make sure the clutch/throw out bearings/etc, are all in place cause something could be getting caught on something...oh yeah...I got a Spec 3 too...but I didn't install it, GM did...um...I've never heard a problem like this...I'll ask around though
