I mean thats what I would do.. the only way I would work on it myself is if I KNEW what I was doing. Im all about working on my own car, but if its something I dont know anything about, Im not messing with it, you could do more harm than good.

:iagree: The dealer is the best place to take it. They should recognize the issue (SOMETHING caused the fluid to disapear) and if they loosened or overtightened something during the last service, they may fix it completely free. I would just hate for you to be driving down the road all proud of the DIY you did replacing the fluid to find out that the fittings released all of your fluid while driving. That stuff is slippery!!! Saw a car go off at VIR because a car in fron of them lost their clutch and dropped fluid.

wowwwww, thats never good. :facepalm:

That's the weird thing though. I've never seen a fluid leak under the car. That would have definitely set off alarm bells

So no auto shops (and I mean none) around here have Motul. I'm just going to take it to the dealership and let them do their thng with whatever the nismo stock fluid is

Man, that really sucks. Hope you get it all sorted out. The reservoir is basically there to prevent air in the lines. If there's a tiny bit of fluid left in the reservoir, you can still top it off. But if it's gone completely, there will be air in the lines when you add more, and that requires that you bleed the system.

I read the directions from the manual and we could do it but I don't want to chance it especially since it's under warranty

Yeah, and I meant to add the fact that it was randomly out of fluid would be concerning enough for many people to just have it towed to a competent shop.

it is now 8:09PM and my flatbed tow truck that was supposed to show up at 5pm is still not here. USAA is now cancelling it and getting me another one. Maybe I'll get to bed before midnight considering i'm in an all-day workshop tomorrow again.

geeeeez. damn tow truck drivers, thats ridiculous.

Called USAA to request a new towing company. I know the guy who owns it because he's in a dart league with one of my friends. Had no idea they were an option. They got here in 10 minutes o_O

Dealership is the place man...

You lost all that fluid, so something is wrong... if they find it, it should all be covered. refill and fix.

Yep, it's at the dealership now. The guy hooked it up and I warned him about the wheels and then stood behind the car.

He goes "I'm going to release the parking brake now"
I said, "Ok"
He said, "You might not want to be standing behind the car"
I said, "Well if it rolls backwards and squashes me you're going to have bigger problems than a wrecked car you were supposed to tow"

He laughed.

I for one am excited to see the dealers finding here. Something sounds odd there. Please keep us posted.

Fairly confident I didn't have anything to do with this UNLESS:

-Dyno pulls. I had quite a few while tuning the car. Would that do it?
-Abuse of synchrorev match while downshifting.
-Z1 silicone hoses weren't reconnected properly? This isn't likely though since there wasn't a clutch line - just a brake booster hose.
-Gremlins

Grasping at straws here.

Want to reiterate this wasn't a catastrophic clutch failure. I've seen first-hand what that looks like. This was odd. Monday, the clutch "stuck" down towards the floor a couple times but with no grinding/burnt clutch smell. Oddly enough, it would still engage fine but the friction point was almost on the floor. I fixed it by flipping the clutch pedal back up with my toe. I assumed it was just getting caught n the floor mats.

Drove the car home from work on Mon night with no issues. Parked and went to bed. Got up in the morning, and the car simply would not drop into gear. The clutch pedal feels totally disconnected. I could/can push it down to the floor (it sorta clicks) and pop it back up with my foot.

I have $10 on it being a leaking CSC but the leak wasn't crazy so you didn't notice it. I mean the **** doesn't evaporate. My car was delivered August 2011 so its 1.5 years old, I have 15k miles logged in it and is nowhere near low.

Just a suggestion... Ask the dealer if they have any GT-R brake/clutch fluid. It may be Nissan branded, but I think it is upgraded fluid over the Z. Just a thought.

Good luck!

The R35 clutch fluid is what they put in the Nismo Z according to Nissan.

I've learned something today. Nice to have a NISMO! Good luck with the repair.

This is correct. Slave cylinder failure.

Replacing under warranty. Should have the car back tomorrow / early afternoon.

Sweet! well...atleast for me getting it right haha. On the plus side. 0k miles on that new CSC :tup::tup:

Its good that they diagnosed the problem, hopefully you dont have anymore hiccups.

Looks like it will all work out well with the slight inconvenience. At least you weren't on travel in the middle of nowhere land. Glad to hear it will be fixed at no charge to you. Plus, you are now more aware of clutch related issues than you probably ever wanted to be!

I had a slave cylinder go out on the eclipse, ohhh man it sucks, luckily it didnt cost a fortune to fix.

Yep, you nailed it. Minor inconvenience and I can now diagnose yet another Z failure. Thanks for all of your help!
Man it started to go on Monday. It very well could have gone out on my way back from the gym. I had to pop the clutch pedal up twice while I was driving.

I got a mitsubishi outlander as a rental and man is this thing weird. It's a SUV with crappier than usual handling and...paddle shifters.

I do not understand paddle shifters on a SUV

Hi all,

I'm new to the forum. I'm having similar issues with my car. I have a full HP Logic Twin Turbo kit and engine build. It's a 2009, 36,000 miles on it.

My clutch pedal is stuck all the way to the floor. Only my situation seems to be a little different because my fluid reservoir is still full.

The car has sat for 3 days because I thought it may be a heat issue and I started it today to pull it into the garage, and my clutch pedal depressed about an inch before getting stuck.

Does anyone have any insight on what could be going on with mine? Could it be the slave cylinder?


Thanks in advance.

So uh...you're running a TT build with the stock clutch?

Questions:
Can you pop the clutch up with your toe / does it snap back all the way up?
Any smells/wacky delays in acceleration?

Dude, you need to have your car towed to a mechanic.. simple as that.

Lack of fluid is only one representation of a failed CSC. Your issue sounds very similar and may in fact be a failed CSC. Is your clutch/flywheel/CSC all stock?!?

Hell no with a stock clutch. Lol. But it's not an after market slave cylinder.

The clutch pedal will snap all the way up if I do it with my foot. But as soon as I push it, it will return equally as fast to the floor. Do you get what I'm saying?

No smells or delays. I drove it about 12 miles with no clutch keeping the car in 4th gear. No slippage or funky smells.


Towing it is going to be a bit of an ordeal since the car literally sits 3 inches off the ground. I'm looking more to gain insight on parts to buy for when I can finally get the chance to get it up on a lift.


The CSC is stock, not the clutch or the flywheel.

Yeah that's exactly what mine was doing. Very likely the CSC or a leak/blockage between the CSC and the fluid resevoir.

I'm with E/W though... If you can't get it to a mechanic, find a mechanic and bring him to the car.

Probably me just being paranoid but I'm wondering if the CSC leak I had was indicative of a large clutch problem. Makes me nervous... Dealership would check that you'd think...right?

Negative on a larger issue. Known issue with the CSC, just like the steering lock issue. You should be fine now that it's been replaced.

Sooner or later a slave cylinder will go out on manual transmissions.. I've come to notice.

Hopefully it won't happen to me but who knows

Ohh its gonna happen to you, for talking bad about the V-TEC phenomenon.. :roflpuke2:

Thank god. I mean hypothetically, a slipping clutch COULD cause the fluid to overheat and make the CSC spring a leak. Was hoping someone would say exactly what you just said.

I'll road test in 4th gear anyway just to be safe.

:facepalm: :icon23:

OEM CSC is known to fail when paired with a pressure plate that requires more bearing load to release than the OEM pressure plate.
