I have a 2009 Cobalt SS with the LNF transmission. I've gone through about 7 or 8 slaves now (some high performance) and we still can't figure out why or how they keep blowing out. It first had a stage 2 Spec clutch and I thought that it was too strong (or maybe it was just defective) for standard slaves so i bought an OEM clutch. Still blows out the slave. All of the slaves have blown out from the back seal where it bolts on to the trans. I'm thinking perhaps the master cylinder is over pressurizing the slaves and that's what is causing them to blow. But as a guy who doesn't know a whole lot I'm not sure if such a feat is even possible. I'm at the end of my wits and willing to do anything just to have the car driving. PLEASE HELP ME!!!
