So I'm driving my 05 GTO and the clutch stopped working, I stopped and checked the fluid and it was gone. I filled it and pumped the clutch and all of leaked from the bottom of the tranny. I believe its the slave cylinder but I'm not sure. Anyway I bought a new one but my mechanic is telling to buy a new clutch so that I wont have to pay the labor again later. If I get a stage 2 clutch do I have to change other parts?
