A couple Odd things about my Clutch

Chuck33079

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.

If the car is under the manufacturer's warranty, then any Nissan dealership will service the car. It's worth asking locals which dealers around you are worth working with and which are to be avoided though.

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.

Yea im doing that as we speak as well as yelp and other business related sites where I can see reviews. I know this might be a dumb questions, I only assume that my car is under warranty, being a 2013. Is there somewhere I can check the warranty on my vehicle. It was a clean title and such.

The warranty has two restrictions- time and mileage. Look in the book that came with the car. If memory serves, the powertrain warranty is 5yr/60k. Bumper to bumper 3yr/36k. As long as you're under the time and mileage, you're good.

Minsu, please let us know what the dealership discovers. Obviously, since I'm experiencing similar symptoms, I'd be interested in knowing the fix. I was thinking the vibrations might be trqced to the tyranny mount (???), especially since they become most apparent when upshifting at higher rpm when the engine and tranny are under load. Maybe in my case the tranny mount wasn't properly aligned when they reinstalled the tyranny. Anyway, let us know what you find out from the dealer.

There is no way to probably align the tranny mount. Its attaches to the end of the transmission and a brace goes on top of it and bolts to actual mount and the frame. Its idiot proof as far as install goes, trust me. I've seen an oem mount go bad before. It was causing the symptoms you mentioned. The Z1 urethane mount solved the problem.

My mistake. I agree … the tyranny mount is a straight bolt-in as you point out. Could be that my mount has gone bad … or perhaps they didn't torque down the mount or bracket bolts enough. I also was thinking of installing an after-market mount … but have seen mixed reviews. Appears you're happy with the Z1 mount which is good to know.

Minsu

So i just did research all throughout the day and night.
I checked other car forums as well as mechanic forums.
Apparently some other people with other cars have experienced the clutch vibrating issue and says it IS NOT a csc or cmc failure usually.

Some mentioned, throwout bearing wearing? no idea what that is.
Also bleeding the fluid. Or just something wrong with the clutch plate or pressure plate.
Im gonna give it another two days on the road to see what the problem is.

Yesterday the problem went away for about 10 minutes or so while i was driving.

So wierd .

Other cars do not experience csc failure at the very high rate of Zs, so take that with a grain of salt. You've got a warranty, use it. Go in and just tell them it doesn't feel right. Anything wrong is going to be a warranty issue anyway, so might as well at least have one complaint on the books.

I had a very similar problem with my maxima and when the trans was opened up one of the springs on the clutch disc/plate was sideways.

Minsu

Your right, I will also be taking it to the dealer, what are some prevention methods so that the dealer don't take the car for a joy ride. So many storys on our forum alone of the dealer fkin the car up cause of joy rides and other stupid shindigs

Note your mileage before and after. They're going to have to drive it to diagnose, and if you tell them it's a high rpm problem they have to wind it out to see what you're talking about. But if you come back and it's got 50 miles more on it, there might be an issue. If you go to a reputable dealer, you should be ok. Keep in mind most people don't go on the internet when things go well, so the ratio of horror stories to success stories is wildly inaccurate.
