Possible CSC Failure?

KeithF · 06-29-2019, 04:51 PM

Hey Z members! I wanted to get your opinion on something. I have owned my Z for a little over a year and it currently has 48,500 miles. Over the past 8 months I have had 2 instances of my clutch dropping to the floor giving little to no feedback and making it hard to shift gears. The first time was spirited driving in the canyons, after about 30 minutes the clutch just dumped on the floor and I drove her slow straight to the mechanics and 2 blocks before reaching the shop the clutch popped back up to normal and felt fine again. My mechanic just ended up flushing the line and replacing the fluid because he didn't want to charge me for removing the transmission to check the csc since it was clearly working. The second instance was driving to Las Vegas this past week. It was pretty hot outside and around 2.5 hours into my drive my clutch lost a lot of feedback and the engage point was 3/4 of the way to the floor which is odd seeing how high the clutch engagement point is normally. I figured it had something to do with the heat in which the clutch remained weak on the drive back. The clutch has since returned to almost 100% but it feels like it has less feedback and the clutch engage point is a little lower than stock. I'm wondering if I could get some feedback from some of you and what you think the problem might be? Maybe it's the OEM clutch line giving me trouble? Maybe at some point I'm leaking clutch fluid somehow under high heat conditions? Any help would be appreciated! Thank you!

My recommendation is to get a Zspeed CMAK. The last thing you want is your CSC dying in the middle of nowhere and having to get towed back.

Get the CMAK or Z1's elimination kit.

Would you all recommend getting the clutch/flywheel combo with the zapped Xmas for preventative maintenance? Or ride out what’s left of the oem? I was considering upgrading that at the same time due to the transmission already being cracked open to save possible future costs.

Not quite sure why we're shooting lasers at Santa Claus, but as to the rest of the question, yes. I got the stage 1 street kit or whatever along w the CMAK. Doesnt make sense to drop the trans more than once.

sorry, I was a victim of auto-correct! I will probably end up doing the cmak with the stage 1 clutch/flywheel combo. But I havn't had another issue since the trip to Vegas. But i'm pretty sure those are both signs that the csc is on the way out the door and ready to take a dump. Does anyone have a ballpark on how much a shop would charge to install the CMAK and clutch/flywheel?

It cost me 900 to get my stage 1 + cmak installed. Be sure to take your time and find a quality shop. I looked up ab 20 shops and drove by each one till I found one that wasn't high volume and had some really nice, rebuilt older cars outside.

Or just do it yourself. It's not that hard if your so inclined to do so.
