Clutch SC question

ocfoilist · 11-13-2013, 06:48 PM

My CSC just went out for the second time (I'm currently at 67,000 miles) and needs to be replaced. My clutch pedal is about 1" from the floor and I'm fine with fluids with no signs of overheating so I'm guessing that it's the same issue as the first time. I'm sick of the OEM one breaking so I'm going to go with Z Speed's aftermarket one.

But I am wondering how important it is to replace the master at the same time. The dealer also mentioned something about possible excessive play from the flywheel as a possible cause for 370 CSC failures but I have a Stillen lightweight one installed by Stillen, so I suspect that's probably OK.

I definitely don't want to spend any unnecessary money but since I'm going to have to have the tranny dropped is there anything else that you recommend being replaced?

Might be worth it to throw in a new clutch if the tranny is coming out.

Hi Chuck,

I've got an ACT clutch kit installed and it was done last year when I replaced the CSC the first time.

Then you should be good to just replace the CSC and call it a day.

Thanks guys. Someone mentioned that it could also be the throwout bearing. Is there any way to diagnose this problem without first dropping the transmission?

So far, this started about 1 month ago with my clutch pedal getting spongy for about half of the travel distance of the petal. My clutch engagement depth was much lower than normal. But it would come and go with no apparent pattern (wasn't worse with heavy use). Then, on Wednesday it went almost all the way to the floor (perhaps 1" above the floor) and was difficult to get into gear. At that time I checked the fluid and the level was normal and it was not boiling. Since then, the condition has not improved and it is just barely drivable (if I push the clutch pedal firmly all the way to the floor it will grudgingly go into gear). I don't see any fluid leakage, either. The pedal will snap back up when I pull it out with my foot but immediately drop back down to just above the floor with the slightest pressure.
