A couple Odd things about my Clutch
 

Ok so recently ive been driving around. And I havent found a solution to this burning question.

So firstly, when im not moving and i depress my clutch to shift into first, were all good.

Then once im going like lets say 14-18mph and depress my clutch it gets wierd. Heres the specific order of what happens and how it happens.

Driving up to speed to get ready to shift to second.
Depress clutch and shift into second, this is where things get wierd.
I FEEL so much feedback coming from the clutch. Like i feel this incredible vibration that i havent felt before. its not violent by any means, but its a feedback ive not felt the entire year ive been driving.

It cant be the CSC problem cause my clutch is still stronk.

And im not sure if its just cold but yesterday when i was driving as i depress my clutch, maybe 3/4 of the way down i hear a, shwink, shwink.
Hard to explain the sound, sounds like when you sharpen knives? i guess?

Sit there and say shwink, shwink, in a metallic feel.

Lol.

Thank

Don't assume you can't have a CSC problem.

Do you know anyone else around with a manual Z? Let them drive it. Don't tell them about the potential issue until after and see if they noticed.

Great Advice, my friend drives an 09z ill have him test it for me monday!
Before that what are some symptoms of maybe not enough clutch fluid?

Clutch fluid is easy to see. Look at it. If it's low you have an incoming problem since it's a closed system. If it's low there's a leak somewhere. If it's black and dirty you have an incoming problem since the black stuff in it is bits of CSC.

:bowrofl:

I love you minsu! :icon17:

Here are some pictures of my Clutch Fluid.
There isnt any sediments floating or anything of the sort.

Ur csc wear out bearings are going to fail soon. Imho.

Elaborate lol please

:iagree:

Notice how the clutch fluid looks darker than the brake fluid? That means the internals of the OEM CSC are starting to come apart. Right now you've got two options. One is to continue driving it until it fails, and then pray the dealer takes care of you on the warranty. 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 believe the feedback ur getting is from them NOT being round, causes the csc to move slightly in and out, also causing ur clutch to move in and out and transfer these vibrations to the pedal since the csc it self is in good shape. Am a mechanical Engineer, in general that makes me think is what's happening. I could be wrong.

Hmmm, thanks for all the advice, for those who had there csc fail did you have alot of vibrating feedback when you shifted into higher gears, doommonkey, what you said makes sense, about the bearings not being round anymore. Thank you.

I'm not sure about any bearings not being round anymore, but the outcome is the same either way. My understanding is that the internal seals are plastic and they degrade, allowing fluid to leak out, parts that shouldn't come in contact with each other to touch, heat up and self destruct. Again, either way the outcome is the same. Clutch pedal on the floor, waiting for a tow truck.

I replaced the OEM CSC with the ZSpeed HD CSC simply as a precautionary measure in order to avoid being stranded in the event of failure of the OEM unit. The CMC was changed at the same time, as recommended. Also installed the ZSpeed insulated SS clutch line and used Motul 600 RBF as the fluid. Since then I've noticed very slight vibrations through the clutch pedal when shifting at higher rpms (3500 - 4,000). Not sure what the vibrations signal … but there appears to some similarity with your symptoms, at least in terms of the vibrations. I plan to get it checked out when I remove the vehicle from winter storage next spring. Not sure if this simply confuses the issue … but I'm also looking for any advice from others. I'm a little perplexed as to how the CSC could cause vibrations travelling to the clutch pedal … but I guess strange things can happen. A number of CSC failures have been reported … but I haven't seen any mention of vibrations being experienced before the CSC let go … besides my CSC is brand new and heavy-duty. Comments/suggestions are invited.

Im just getting confused cause the symptoms of a failing CSC is soft clutch, dead clutch.
But for me, its been fine. Clutch Wise. The only thing thats weird is when i depress clutch to shift into second gear i get this vibration in my clutch pedal that i never felt before. I read through most of the csc failure sticky but found not one person who had this symptom before their csc or cmc went out. So im not sure what the exact problem might be or if itss even worth bringing into the dealership. I bought my car in delaware and im in NJ and its a 2013 so i still have warranty, but do i have to go all the way back to delaware where i bought the car to get it serviced? It wasnt a nissan dealership it was a private dealership. So Iono im just confused and getting worried.

The vibrations happen every time i shift into a different gear btw. not just second. Its alot of vibrations higher into the rpms while upshifting.
