WTF! Is wrong with my clutch!!
 

It is all the way into the ground and it will not come back up and I cannot start the car. WTF!!

Check your clutch fluid, it's probably black and needs a flush and re-fill. It's a common problem and shouldn't happen if the fluid is flushed regularly.

Other possibility is the CSC failing.

:iagree:

on both


Op you may want take a look underneath the car for possible fluid leak.

If so?

The Clutch Slave Cylinder or Clutch Master Cylinder may need to be replaced.

Either way it's looking like a dealer visit unless you have the tools and knowledge to do the work yourself

OP, its probably a faulty CSC like mentioned above. If your Z is still under warranty you should be fine. I would just buy a heavy duty CSC like this one from Zspeed- ZSpeed Performance Replacment HD Clutch CSC Heavy Duty Slave Cylinder Kit

^These are the way to go. Our stock CSC are crappy plastic design that seem to fail left and right.

It was leaking!! So it might be the slave cylinder hope the dealer doesn't say anything about the stillen supercharger. What do you guys think? Is this a common problem with the z? I only have 20,000 miles.

Might be an ''IF'' on what the dealer does. But I'd personally handle it myself. Buy a new clutch and HD CSC.

Well looks like she's going to the dealer tomorrow and getting it checked out. Thanks peeps!:mad:

people really need to start reading what's been written about the clutch problems before posting a new thread, do a search or at least try to look... I mean there's the same question on this very page. :/

If you have a supercharger and its the oem clutch might not be a bad idea to upgrade it to something that can handle some of the extra power.

Sorry thread monitor! I'm new and still learning I guess I just needed help and needed an answer.

hope it is covered by warranty. Most likely it's both MC and CSC.

I did notice that the resovior was empty!

Stock concentric slave cylinder failed, same thing happened to me. I ended up replacing mine and going with the ZSpeedPerformance upgraded heavy duty one, haven't had an issue since.

+1 to Zspeed. Since you're in Mansfield, it's a pretty short trip to Cincinnati (assuming that's Mansfield, OH).

Z Speed's in Dayton, not Cincinnati.

I'm confident its the CSC, the same exact thing happened to me a couple months ago with only 12k miles. They will probably give you crap about the SC but do mention to them its a junk part with a long history of failures and I do believe there is a TSB on this.

Ya almost definitely the CSC. I did the Zspeed CSC when I upgraded my clutch. 18,000 or something miles ago, no problem.

As for the warranty... I would be very cautious before arriving at a dealership with a supercharged 370z and asking for any warranty work. I believe that you can DEFINITELY get this covered under warranty... but I would call around and test the waters anonymously and see which dealer you find appears to be the most mod friendly. Some dealers can be real jerks about modifications.

Once your car is there, they know they get the work. They get paid better to charge you versus the warranty. So I would try and make the arrangements by phone first.

Pooh. I thought they had set up in Cincy a few years ago.

Well based on their website it's Dayton.

No Mansfield Texas. I'm going to take it to the dealer tomorrow it's still under warrenty.

Yeah. I just found the PM from him last year that said they were 40-45 minutes further North than Cincy. Changes my travel plans slightly.

All the much better for the OP though. Closer.

Oh. To quote Gilda Radner, "Never mind". :icon17:

But why does it fail what's the issue with it?

It's plastic. nuf said

Why take it to the dealer? What is a warranty going to do if they even decide to honor it with a SC? The smart thing is to buy the HD CSC from ZSpeed. You can offered a SC I'd like to think buying a new clutch, CSC, and installation of such wouldn't hurt the pocket. Being you have a SC and the tranny is going to be dropped put a clutch in there.

OP was this with a stock pressure plate or aftermarket? thats the only way i could see u having issues with warranty. aftermarket will put more force on the csc possibly causing it fail prematurely.

btw, if stock, how many miles have u gotten outte the stock clutch with this sc system?

I got the sc installed a couple weeks ago. Not that many miles yet.

slave cylinder
 

my csc went out a couple of months ago and was fixed under warranty (i was told -/+$1200) and if it wasnt under warranty i would have def gone with the heavy duty one SPOHN was referring too. I was told these go out quicker because its (csc) is actually in the transmission bell housing and very labor intensive to replace and gets alot hotter.. and doesnt the stillen super charger come with a 3/36k warranty?

I recently replaced mine with the HD CSC when I upgraded the clutch. The OEM one is a cheap plastic piece of junk. And yes being inside the bell housing doesn't make it any more durable.

If you are going to replace it, ABSOLUTELY go with the HD CSC. It's ~200 more than the OEM one, and you don't want to have to replace it again in the future (especially if you're paying someone to do the work)

Csc buddy. Stock ones are weak. Replace that asap

This thread kind of worries me now as I'm approaching 10k miles. Is it alright to just upgrade to the Zspeed HD CSC with the stock clutch?

is it ok to use the stock OEM clutch with the heavy duty csc
 

Yes the csc looks like it will work with many different clutches. Zspeed performance even asks you in a drop down box which clutch you have (or will have) so they can get you the right fitment for OEM or most aftermarket clutches .:rock::xmas3:

Thanks. It's my DD, so I don't really want to upgrade clutch/flywheel and make traffic harder on myself.

My clutch just went out a few days ago :(, Now they want me to pay 1000 dollars to replace the slave Cylinder. Based on what I've read warranty should cover it so I'm fighting this unjustice.

How many miles do you have on your Z?

Your clutch pedal went to the floor because your slave cylinder failed or your actual clutch has gone up already? If the clutch went up, that would be considered normal wear and tear.

If it's the slave cylinder, then that should be covered under warranty, unless you're running an aftermarket clutch or flywheel.

Thanks guys for all of the info I got it replaced and now time for some uprev tunning we will see what numbers the sc brings to the table.:tiphat:

3yr/36k mile yes. 5yr/60k mile no... unfortunately.
