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

Joelito · 03-28-2013, 07:19 AM

Got my car back yesterday and as strokethis347 stated, there is a new bulletin regarding this issue. The same thing they told Jupiter pretty much was what they told me. They replaced the fluid with the gtr, they couldn't find any leaks and this seems to have fixed the issue at least for now. I'm still worried about this issue reoccurring and me getting stuck again. On the plus side they did cover my tow expense (i don't have road side assistance), and gave me a loaner for the 5 days they had my car.

Wow, took them 5 days to change the clutch fluid and bleed it?
That's got to be a record! /sarcasm

Seriously, what is the difference between the GTR fluid and the fluid in the Stock Z?

Stock is Nissan DOT 3. The GTR is DOT 4 and more than likely is synthetic and has different additives in it.

All brake fluid is synthetic.

Dot 4 has slightly higher wet and dry boiling points. Both are compatible with one another but not dot 5 (albeit dot 5.1 is also compatible with 3 & 4, but not 5).

IMO, at a minimal, dot 4 should be used in any high perf vehicle.

Lazy to read past post. Any particular year model does this problem occurs?
or what Date of manufacture? TY.

Is the CSC an issue with later models?

Hi Akmcmahon,

In this forum I've read about 2013 on down having the CSC failure within 7000 miles and some at 20 or 30,000 miles and some having that many miles with no failures. I detect no pattern and theoretically, because "race car" then power train components should not fail within the boundaries of their use (capability of the engine) etc.

Wasn't thinking when I typed that lol.

Yes dot 5 is a big no no.

The difference between dot 3 and 4 is negligible for a street or street performance vehicle. Unless you are going to track it, if you have DOT 3 in I wouldn't go run out and change it just because it is DOT 3 (your not going to boil it on the street or spirited driving). Also I believe the viscosity is different between the 2.

Took 5 days because I dropped it off Friday 20 min before the service department was closing so they did not get to look at it till Saturday, and of course Saturday the clutch pressure was fine (magic I know) so they let it sit until they can find what the problem was, Sunday was day 3 and they were closed so Monday day 4 was really the 2nd day they looked at it and the pressure was fine again. They couldn't find any leaks of course and didnt know why it lost pressure so finally tuesday they got the bulletin and informed they will be replacing the fluid & to come get it the next day (weds). So yea kind of a long hassle I'm just hoping it was really that and not the cmc warranty or not

I might be willing to change my fluid now before I have any problems. Let us know how it works out. I'm not having any clutch issues now but one never knows....I'm half expecting it but since my car has 12K miles on it (2009) I hope I have a little while before I have to get underneath it.

I'm at 6,700 miles and had to do it :/

Keep this updated, My guess is it will work for awhile then you'll be back for a master cylinder replacement.
