Well when your car starts to slip. Think of it this way, you can go and get it fixed that weekend or a few weeks after. Or drive on it and slip the hell out of the clutch and burn the flywheel till you have to replace that to. Becasue every time or clutch slips its burning the flywheel to. so the longer you wait better chance you will have to replace the flywheel to. I was told to replace a clutch at the dealership in Everett,WA it was 1750.00. thats what a mech told me they charge people. he only charged 500 if you bring your own clutch.
