my clutch started slipping relly bad so i bleed it and it stopped for a couple days and than started doing it again i pulled the trans last night and removed the clutch and the disc still has fiber left on it its a little dis colered but the center looks purple from heat and the pressure plate is discolored and same with flywheel from heat my question is why is it slipping if the disc still has fiber on it and should i just replace it seance i have it this far apart?

Look for wet surfaces, or any oil leaking from the main seal on the drive shaft. It does not take much.
