Lt1 Clutch Problems

just a note, but when i had air in the lines (although this is not the lt1 style clutch/hydraulics, but rather the 98+ style) if i was in 4th gear and floored the car, it would slip

actually, it slipped all of the time until the day i spent 3 hours with the mityvac making sure i got all of the air out, and since then it has not slipped even once
