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

KoolKarmaJoe

From what I learned from others who have either had problem with CMC or CSC, is that when one of the two fails you are better to replace both at same time. Also going to a HD CSC is highly recommended. You may also wish to go to a "insulated" version of the short CLUTCH line so as to ward of heat to fluid. This is the second time my OEM CSC has failed. Never again will I buy a OEM CSC . The Nissan part is crap!

I only tried to count those with the CSC failure so I skipped several that had confirmed it was the CMC and not the CSC

for EVERYONE that has experienced or even are concerned for yours to go out give Nissan North America a ring and tell the rep you're issues or concerns. 1-800-NISSAN-1 and file a complaint with the NHTSA here https://www-odi.nhtsa.dot.gov/Vehicl...nt/index.xhtml

Z's and G's prior to 2007 (before the HR engine) used an external slave cylinder with a clutch fork pushing on it. This is pretty easy for maintenance because there's no need to drop the entire transmission to service the slave cylinder. With an internal slave (CSC), it pretty much lightened up the clutch effort. Lots of cars use CSC nowadays, but all of them eventually face the same issue with leaking and whatnot. The Valeo-sourced CSC body is all plastic, which is one of the factors contributing to these problems. For mine, the o-ring on the piston slipped off. I don't even track my car, drag raced, or even dumped the clutch. There was never a situation where the pedal sunk itself to the floor other than the stiffness in the winter.

Anyway, the elimination kit ditches the internal slave for an external and fork setup.

Simply create a spreadsheet and share it on Google Docs. If you like, I can edit post #1 to include a link to the document.

[EDIT] Please PM me if you want to volunteer with edit permission.

Ok looking for some opinions. Recently my clutch has been making a grinding noise just before engaging fully in 1st and 2nd gear. I took it to a shop and they said sounds like throw-out bearing. I believe we have the CSC instead of a traditional throw out bearing. Has anyone seen this symptom of the CSC failing or could it be something else? Thanks in advance.

Thought I would share my experience with this issue.

2009 - 49k miles - out of warranty - Central NJ

Day 0: Clutch pedal not returning all the way up.
Day 1: Car won't go into gear. Notice clutch fluid reservoir is dry.
Day 3: Refill fluid and drive to dealer. Hopeful that the flush and GTR fluid from the TSB might save me money. Still was a rip off - $320 for parts + labor. Clutch barely makes it back home. Read this thread.
Day 4: Order OEM clutch (disc + cover), OEM master, Zspeed HD CSC. All from Zspeed.
Day 6: Parts arrive.
Day 8: Car towed to private repair shop. 17 miles away, I didn't want to chance driving it. After showing up 2 hours late, we get the car on the flat bed tow truck. Tow truck blows a tire about 1 mile from my house. It was a long day :-(
Day 10: Back on the road.

Parts ~1070 (incl'd shipping)
Labor ~900 (incl'd tax)

Dealer wanted almost $4,000 (!!!!) which, granted, included new OEM (dual mass) flywheel - but god damn they are a rip off.

So for the people that want to fix this issue even if the CSC has NOT failed. What is what we have to replace/buy in order to avoid this whole CSC issue? Just replace the CSC with the Zspeed CSC? that's it?

Is this the part?---> http://www.zspeedperformance.com/ZSp...SC-zsp2006.htm

Thanks in advance.

Zbrah

^Yep, replace with the HD CSC AND your oem master cylinder at the same time to prevent future problem.

Does the Master Cylinder needs to be Zspeed as well or just OEM?
