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

SkipinJupiter · 03-22-2013, 08:07 AM

Update: Ok, service writer came over with this.... Checked out the system, no leaks and fluid quality look ok. They checked the service bulletins and found one on the problem... "We read the bulletin and this is how Nissan wants us to handle issues like yours when someone brings in a vehicle and reports your issues... We are going to flush/upgrade your fluid to GTR and hopefully this will fix the problem.
I'm almost ok with that to be fair because its acting normal today (naturally)... I might be back again but I can't expect them to start replacing stuff without evidence. No mention of any charge for the work/fluid/bleed.

Wow - Good to know. Thanks for the update. Hopefully that would cure your problem, but somehow a little voice inside my head says "don't know about this..." . Just my untrusting self in what the service tech said - I guess... Keep us posted.

SkipinJupiter, sounds like a load of bull. How did they check the system for leaks without dropping the trans. When the csc fails, it leaks inside the bell housing, not outside.

What was their explanation for loss of pedal pressure [if there are no leaks]?

Looks like its my turn to play. On my way to the shop after running a few errands locally I lost all pressure on my clutch. I had it happen a few times before but it would magically get the pressure back the next day but today it fully gave out. On my way! To the dealer right now on the tow lets see how this goes. 2012 with 6800 miles and got it 4-19-12. I saw a few people talk about the 1 year 12k warranty can someone educate me on it because I am still under 1 yr and never heard of it

Update: got a call today stating they found the problem and they are saying it is the hydraulic oil that is bad. So they are changing it tomorrow

Just to confirm Nissan did recently release a TSB stating to use GTR brake fluid to cure/avoid this problem.

So am I correct in assuming that if we change our fluid from DOT3 to DOT4 we'll avoid this issue???

What are the hazards of leftover DOT3 mixing with DOT4 if we attempt this, is there an incompatibility?

I get the feeling I'm reading too much into this and the OP actual problem is CSC or MC but I'm not a practicing mechanic.....

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.

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

Fountainhead · 03-29-2013, 03:59 PM

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.
