Easy slick. I'm not a Nissan tech. I have only seen the underside of my own car. Someone who works on and fixes these cars everyday told me this and said that they would check it out and correct anything for free. How is that a "bandaid"?

Lol, maybe they can put in the magical "GTR fluid" and make it all better.

The funny thing is that when I had the CSC and master replaced last Febuary, they noted that they did put the GTR fluid in. 6 months later when I flushed it with this same problem, it was toast. Maybe the shop that did the original repair lied?

Thats why I went to the TYP 200... but here we are again.

Because it's not any type of fluid issue. It's a failing CSC/CMC.

LOL, my wonderful clutch is rattling and making noise when the clutch is depressed. I feel it in the clutch pedal also. I want to take it in to the dealer (old friends) but I don't want just more of the same. I most definitely won't put up with any "it's not under warranty crap". My CSC is still good at the moment but it is only a matter of time. I loath this sorry design.

this is unfortunately a clutch issue and you can't get rid of it, unless something is broken and you have your own unique problem.

juld0zer · 11-04-2014, 09:18 PM

the factory fireshield over a section of the clutch line near the bell housing is inadequate. it is possible to develop similar symptoms with just normal street driving because of the proximity of the clutch line to the cat.

You did mention that you get the same symptoms after cruising on the motorways which seems odd because the airflow would keep things tame.
With the warm ambients and traffic here in Sydney, i resorted to replacing the fluid with RBF600 and wrapping almost all of the clutch line near the cat with exhaust wrap (both the hard line and the flexible section), all the way to the bell housing.

That cured the issue and i feared the traffic no more. This was before i had the CSC replaced due to fluid loss. I think the dealer removed most of the wrap when they replaced the CSC but i havent really noticed the mushy pedal issue since the replacement. Fluid level is unchanged, colour is perfect. I'm happy enough even thouggh the clutch feels a bit too on/off for me. as in the friction point is very narrow, but im not going to disturb anythinf until it really goes south. good luck!

After I had my Zspeed csc installed, I went almost a year without that fiberglass wrap on the clutch line. Never had any issues either.

?

Not sure how many miles you put in during the 6 mos period, but the clutch fluid should not be very dirty. It may be that the internal seals are wearing prematurely and caused the fluid to turn black.

The csc was replaced by the dealer under warranty 18 mos ago with 10k miles. The fluid is still very clean (golden clear color) and the clutch is working well.

just to add a little fuel to these fires.....

the crummy CSC/hydraulic clutch system in the 370 is one of the MAJOR factors in me selling my nismo. i had the car 4 years. i went thru the first CSC in 24k miles. the dealership even said my clutch looked great with zero abuse.

i babied that car, and i babied it after i had the CSC replaced. The nismo was my daily driver which it can do perfectly fine as long as you dont drive the car aggressively. but who the hell wants one if you are too scared to break it???

i sold it at 69k miles. i wouldnt be surprised if the next owner gets 5/10k fun miles before it all breaks again.

driven hard these "OEM" systems will only last a year. babied you can get away with several more.

Lest we forget that MOST(not all) dealer techs are guys who have graduated from the oil change department after taking a year of vocational and a two month "factory training" course on how to use consult3, they know enough to fool you but when something actually goes wrong they end up calling nissan tech line about it because they don't OR AREN'T ALLOWED to actually fix what is wrong. They have to follow Nissan procedure which is only in place to keep nissan from having to spend too much by actually warrantying what is broken. And the service writers are just salesmen they don't chit 3/4 of the time.

I noticed on/off feeling you mention when I did a flush months ago to recover from an un-drivable situation. The flush made all the difference. I also looked at the heat wrap option. It's interesting to hear that wrapping the tube solved your problem. It's pretty clear that it was in fact heat related. Did you have another OEM unit installed?

nis350 · 11-05-2014, 02:57 PM

The CMC and CSC are really simply parts with metal rods and rubber seals. I think the issue with the z is that the CSC in situation inside the transmission where the heat is much higher and worst of all, the labor cost involves in replacing it because the trans has to be removed.

I replaced my Miata's CSC (external mount) in about 45 min. and the part cost $40.
