Sticky: (Official) 370Z Clutch Pressure (CSC) Failures

Spooler · 02-27-2017, 08:54 PM

Well, my old regional service rep retired a couple of months ago. So much for that. CSC failures are not always catastrophic. I have had too many to count on older Z's. Nothing new to me. Been dealing with it since 1986. The problem now is it is in the bell housing. I checked with my parts guy and the CSC part number changed several years ago. That normally means that Nissan started using a different supplier. If they had several changes in the last couple of years that would mean they were upgrading the part. That doesn't appear to have happened.

putting gtr fluid will prolong it some, but eventually you'll just have to replace it. zspeed or z1 motorsports.

My failure to report:
Sport package 2015
Miles - 10500

Symptoms: Spongy pedal not returning
Diagnosis: CSC failure. Took to dealer who was going to put in the GTR fluid to resolve spongy pedal. Lead tech put car on lift and found clutch fluid in tranny bellhousing from leaking CSC. Tech found fluid was trashing clutch.

Major Parts Replaced:
-CSC
-Clutch disc
-Clutch pressure plate

~$1800 in warranty repair. Dealer returned car in one day; was hassle free repair through service advisor Patrick at Nationwide in Baltimore.

How hard do you drive the car? Just curious. Did they put in another stock CSC? You know what that means :-)

I'm replacing mine this Friday with Zspeed CMAK external release, and hopefully drive worry free in that respect.

It was an easy repair because you were within your 3year/36k warranty...

once you get outside of that, you'll be on your own.

Getting mine replaced today on my own dime. I'm not waiting for it to fail. 28k on the odometer.

Hello....

How you feel the clutch now with the CMAK CSC delete kit?

It happened to me when the car was 4 months old, and now 4 years later and 20,650 miles on the Odometer. I'm considering the CMAK delete kit.

Thanks.

It's worth it to me :-). I do some work myself, such as brakes, spacers, exhaust and fluids, but I'm not going to lay on my back and replace the CSC. Besides, I got her tuned while I was there.

I consider a day at the speed shop a good day!

Mine didn't fail yet but my resovior was completely dry. Took it into the Nissan dealership and they recognized the issue and said they would warranty replace it. 35k on the clock, dodged a nice big invoice.

Mine went out on the track at Daytona . Only had 22K on it. Replaced with new external Z1 CSC for the next time.
