He doesn't have a problem yet, but he will if he doesn't change the fluid. All CSC will fail eventually. Even on the older Z's that were on the outside of the bellhousing, They failed too. Pisses me off because they have always had issue no matter what the brand. What did Nissan do? Go and stick the dam thing inside the bellhousing. Now they are making it a pain in the butt to change. It used to only take 10mins to change one.

If your very agressive on the car it could be possible that youve worn down your clutch, or badly scored the flywheel due to heat. If your recently not driving as aggressive then the clutch and flywheel surface are evening out again causing the vibration to go away. Just some food for thought. Everyone on here likes to think the csc is the root of all clutch problems. I have 50k on mine with no issues and stock clutch with occaisional track use.
But by all means go to the dealer and have it checked out. However if the dealer finds its an issue related to what i said then it wouldnt be covered under warranty. Clutches/flywheels are considered a wear and tear item and are easily damaged or worn down by the user.
Also the throw out bearing is integrated in to the csc on our cars. Think of the csc as a 1 piece throw out bearing/slave cylinder. So when you depress the pedal the csc pushes out and contacts on the pressure plate. If your clutch and flywheel surface are scored like i mentioned thats when it would transmit the vibration.

Thanks for the info, im piecing everything together. Hopefully its not a big issue.

The other is to buy the HD CSC now and put it on a shelf, so when it fails you can sweet talk the dealer into installing it instead of the OEM piece when the car shows up there on a flatbed.

Someone soon will chime in about the magical "GTR Fluid" that will cure all your woes. It's a band-aid. The problem is a failing part, and fluid will not save it. It will only prolong the time until the bearing fails.

I consulted Ryan at RJM who makes the RJM pedal assembly to obtain his opinion since he's a bit of a "clutch" guru when it comes to the Z. Evidently, he has heard from a number of owners of newer 370s about vibrations felt through the clutch pedal (factory as well as RJM assemblies) when shifting at higher rpms. In these cases, the problem has been traced to the factory clutch, and not the CSC. Changing the disc and pressure plate apparently solved the problem. Unfortunately, it's a costly fix since the clutch is not covered under the powertrain warranty. Anyway, that's the input from Ryan. He recommended going with a Southbend Stage 1 or 2 clutch for daily driving … which is consistent with Joe at Z Speed.

Well thats good to know and consistent with what I said.

40 to 332 · 11-27-2014, 11:42 AM

Just to clarify, according to Ryan at RJM, the problem has been traced to the factory pressure plate. The problem evidently was solved by replacing the pressure plate. That said, the CSC has to be replaced at the same time since it can't be re-used. Not a good situation!

Minsu · 11-27-2014, 11:50 AM

Dammit.

IDK why all of a sudden the OEM pressure plate is causing this. Other model years didn't have these issues and the flywheel/pressure plate are the same for every year. And once you have the transmission dropped, changing a csc is no big deal, that is the easy part.

nismolucino · 11-27-2014, 01:15 PM

At that point might as well do a lightweight flywheel a new clutch and upgraded csc or csc elimination kit.

IDK either. Just reporting what Ryan has discovered. Could be that a bad lot of pressure plates were installed on certain vehicles during a production run. Again, IDK. Agree that changing the CSC is no big deal. However, it only adds to the cost of the repair. It'll be interesting to learn what the OP discovers at the dealership.

Don't worry. Mine does the same thing. I feel it at idle. I know it is the pressure plate. I am going to drive it as far as I can, then do a total upgrade. I get feedback from the clutch with the pedal depressed and I hear a clicking sound and feel it in the pedal. I don't always get it. I will guarantee one thing. I will fling that dual mass flywheel across the yard. Told the dealer about it and they were not helpful at all. Hence I told them I would yank that junk out and put a proper clutch, flywheel, and CSC setup in it. Basically, to shove it where the sun don't shine, they were not getting any of my money.

Parts guy I have bought mucho parts from says he keeps a clutch/flywheel on the shelf for the 370z so it is not uncommon.

Well, that thing is so heavy you won't be throwing it very far lol. A lightened flywheel was the best mod I did to my Z!
