yes, replace both at the same

Sticky: (Official) 370Z Clutch Pressure (CSC) Failures
 

Joining the party... same symptoms, same solutions. Question is Zspeed ezstreet stage 2 or 3 quiet, or South Bend Stage 3? Already ordered the RJM Tilton pedal kit. CMAK is a given.

You dont need stage 3 if you are not boosted or planning on boost. If you are boosted or really beat the crap out of it, Track, Drag, Time Attack etc you may want to go with the Stage 3 or contact me for the Stage 2+ kit we also offer (not on new site at the moment)

EZ Street is good for just about everything but more for a daily driver, normal hard driver type work and is our most popular, comfortable kit for mixed use.

ZSpeed CSC for the Win!
 

+1 for Joe at ZSpeed!

After two failed stock CSC units from the dealership within a year, I talked with Joe and got his heave duty CSC unit. That was back in early 2015. When the second one went out, Nissan installed a new master cylinder and I talked them into installing the heavy duty CSC instead of yet another OEM unit. I have had ZERO problems since! I dont track and its a daily driver. I have only flushed the fluid once vs every 3 months with the OEM garbage. I also removed the clutch pedal spring because I hated how it masked the feeling of the hydraulic system.

Joe did this replacement right! Even the Nissan tech told me that he has never felt a clutch feel so good in these cars after they test drove it! What does that tell ya? :icon17: Keep up the great products ZSpeed!

Can anyone recommend a mechanic or shop to replace a CSC and clutch in San Diego? It seems that most shops to get this type of work done other than the dealership in my area is in LA

I googled nearby transmission shops and drove around until I found one with a pristine rebuilt '57 Chevy and other such cars out front... figure someone who puts that much into a car would take it somewhere they trust.

The drive to Specialty Z is worth it :twocents:

So mine failed a couple of months ago. only 26k on it. i asked them if i got my own csc if they would install it under warranty. they said no:shakes head: i talked to them about others having the same problems even with newer cars and said i didn't want the same cheap part. the only thing they could tell me is it had a new part # and that usually means something changed. maybe they upgraded it? i had no choice i had to let them fix it. i just couldn't afford to not have it fixed under warranty.

If under warranty. Let them have the headache of fixing it.

CSC - Class Action Lawsuit - California
 

If you live in California, you may be able to join the class action lawsuit against Nissan if you experience shifting problems, or if your CSC failed:

https://www.sfchronicle.com/news/art...l-14189523.php

The law firm handling the suit is 'Capstone' at www.capstonelawyers.com

Any shops in Socal you guys would recommend to get the CSC replaced/ upgraded? I'm in Long Beach.

Interesting about the class action lawsuit. Any of you part of it? Trying to decide if it's even worth the trouble to join...

It's a bit of a drive for you, I took mine to Fast Intentions in Simi. The cost was the same as going to Nissan, but it is a much better clutch and if you plan to boost or track, it'll last for you.

Good luck

The only people that win in class action lawsuits are the attorneys. The company usually get off with a slap on the wrist or at worst a minimal fine, and the attorneys get paid fat. The customers who got screwed essentially get nothing. Waste of time and resources...

I just purchased 370z and want to replace my csc now before it goes out on me. Is it better to go with the heavy duty one or eliminating it?

Consensus is to eliminate with the CMAK.

:iagree:

Okay thanks! I'll get it done as soon as possible :D

Hey guys, had my car for couple months now. Recently started to feel "softer clutch feel" after couple harsh driving. Fluid was black... Changed the fluid for stoptech 600 fluid. It's still doing it but less dramatic.

370Z CSC Failure
 

2016 370z with 20,000 miles. Csc failed. Replaced with Z-1 Elimination kit. Total cost 1,300. Very insensitive of Nissan not to fix an ongoing problem.

https://drive.google.com/file/d/1ClD...w?usp=drivesdk

*Sigh*...2015 370z Nismo Manual. Just passed 35k miles and has been rock solid since I bought it almost 2 years ago at 8k miles...until this past Saturday. I absolutely love this car and it has been a dream to own one.

Since I've been working from home for the past couple months, I drive my Z about once a week to just get out and keep it running well. I may have felt my clutch acting funny a couple months ago here and there, but nothing significantly. On Saturday, all of a sudden, the clutch was very week and I was barely getting any pressure back. I am well aware of the CSC issue and it is the main reason why I got it CPO, among other reasons. There were two times while I was driving on Saturday that the clutch wouldn't come back up, so I had to lift it with my foot. Pumping it would kind of help, but driving on the highway did not help. I quickly turned back around and went home when I noticed things getting bad. I actually even stalled at a stop sign because I wasn't getting any clutch feedback...and, yes, I know how to drive stick very well. Just to make sure it wasn't a leak, I checked the fluid level and everything is topped off, so I guess this is good news and bad news.

I just find it so interesting that there is no common factor among those who have been plagued with this issue. It spans from brand new vehicles to vehicles that are crossing 60k miles with all kinda of different background stories. It's very discouraging that Nissan hasn't done anything about this, even with a class action law-suit, which I understand can be pointless at time, but it really does shed light onto the matter. Also, I do not think it is a coincident AT ALL that Nissan changed the clutch set-up to an Exedy system - I haven't really heard any issues with this newer system, but maybe you all can chime in.

Anyways, I am obviously trying to get Nissan to pay for this is ridiculous manufacturing/engineering flaw, and I've read the PITA stories that people have gone through, but I'm giving it a shot. I had one local dealer basically say I'll have to pay for everything and that they don't have many Zs that come through. The next dealer I spoke to, the lady knew what she was talking about and assured me her GTR tech would diagnose my car and she even waived the $150 fee, which I appreciated. She also mentioned it sounds like it would be covered under my CPO warranty if it isn't covered by Nissan. She said Nissan has one of the best customer services...sure, I'll go with it. I heard back from the tech today and he said the "CLUTCH SEEMS OK SINCE HEAT IS A FACTOR IT IS POSSIBLY THE RUBBER LINE THAT GOES TO THE SLAVE CYLINDER." So, before removing the transmission to actually see if it a CSC issue, he wants to "REPLACE LINE FIRST AND BLEED SYSTEM AND RE-CK MAY NEED SLAVE CYLINDER ALSO." This is a $481 bill to me and they will not cover this. So, what guarantee do I have that I pay $481, the new rubber line doesn't fix the issue, and I have to pay the $1-2k it costs to replace the CSC. Sounds like I'd be really effed then. Also, do you guys/ladies think they would replace it with the new exedy system rather than the same plagued system?

I've called Nissan NA to speak to them about this, but apparently their lines are busy, so I haven't been able to actually talk to them yet. Any advice? I'm currently w/o a car and have been hitching rides with my wife.

Thanks!

I went thru all of this. Both with my 06 350z and my current 09 370z. On the 09 it was happening at around 18k miles. Do yourself a favor... I have a few words for you. And I know you'll be happy. Joe at zspeed. And Ryan at rjm performance. Get this

The clutch master cylinder normally causes this issue if there are NO fluid leaks or loss of fluid, Master is $99 on our site, If you are tight on cash at the moment, replace the master and re-bleed the system first and your issue should be resolved until the slave dies...

Thanks for the prompt response from both of you. I've heard great things about both companies. Is the adjustable clutch pedal from RJM necessary or just a nice to have? I don't track/race my car - just DD and the occasional spirited driving on highways. I'll definitely need the complete clutch flywheel system as I don't want just a quick fix. Fortunately money isn't tight and I prefer doing things right the first time, but I was just really hoping to have Nissan cover this. My birthday is tomorrow too - THANKS, NISSAN!

BTW how much is it to have this done in a shop - on average?

Both are neccesary in my opinion. I just got the pedal installed last week. Had the zspeed cmak and clutch for about a year? Wish I did both sooner. I'm a casual street driver. The stock pedal is just too finicky for me.

3:20 mark for a better explanation. But I can assure you, shifts, especially 1st to 2nd are wayyy smoother with this pedal. And the clutch feel is much better.

2 hours for a good mechanic to install the pedal. And some time afterwards for you to try the pedal and then make adjustments. So maybe 150 to install? I paid $550 in nyc for the complete cmak and clutch install.

I got a case # with Nissan a couple days ago and they called me yesterday to let me know they are "investigating the issue." I was told they will let me know the outcome on Friday. I'm just hoping my Z isn't being joy ridden while it's sitting in the shop...hopefully the dash cam that is pointed at the driver's seat is a good deterrent. I'll keep you guys posted for information sake. I'll either get lucky or I'll be placing an order to Zspeed this weekend. I know you all have warned me, but I'm just shooting my shot.

Side note: I'm not sure if I'm being dramatic, but the outcome of this may or may not influence my loyalty as a returning customer to Nissan (especially if they were to revamp the Z).

I'm afraid you're wasting your time, and the point of my rant was to save you your time. Thousands have gone down the road you're on. My last attempt. Get your car outta there, meaning out of the hands of that Nissan dealership, and into your custody, and get rid of that concentric slave cylinder, and that stock pedal. There's no other way to put it. And I'm only saying this to you because I'm gathering from what you said, that you are willing and able to invest the funds required to right this problem. Respectfully. Did you read through this whole thread??

Sent from my SM-G965U using Tapatalk

lol NNA isn't going to do jack for you. Same as that dash cam. What you're really hoping is that the idiot who wants to joy ride doesn't know how to unplug the camera in the back although it's likely they don't give two shìts anyway. What are you going to do? Sue the dealership for driving your car? You're just wasting your time :rolleyes:

Yes, and I appreciate you taking the time to respond. I figured I wouldn't lose anything by at least giving it a shot as I have the time right now. There have been members in this thread that have been able to get it fixed under warranty. Anyways, I'm just getting worried now so I'm trying to pick my car up this evening based off what you are telling me. The auto shop will probably be closed, but I'm hoping I can get it via sales dept. I admittedly did not read the entire thread...it's 120 pages, but I did read many.

Thanks, I guess?

To all, I'm not the most technical person, but what exactly do I need aftermarket? The companies I keep hearing about are z1motorsports, zspeed, and RJM. I obviously do not want OEM parts, as that is what is causing the issue in the first place. I've also seen a CSC delete kit - I'm not sure what this is. Please help. Thanks! I'll try giving Joe a call as well.

https://zspeed.com/product/zspeed-st...clutch-system/

This is the kit i am going with. I am not an expert on the 370Z platform
but I have researched this for myself and have only read good things.
This was also recommended to me by Rob at Z car Garage in San Jose CA.

Thanks, man. I have been looking at this too. Although Joe from Zspeed mentioned the stage 2 - he actually responded to my original post in this thread the other day. Their shop is closed, but I need to call them tomorrow to verify. My main question is why I would need a new clutch too.

Thanks!

FYI I was able to "rescue" my car a couple hours ago. I had my wife rush from work to come get me (she's the real MVP). It's a long story, which I will spare all of you from, but the dealer actually started to work on my Z w/o my consent. I even told them specifically not to until we hear back from NNA. All of a sudden they weren't charging me the $481 for the rubber hose either. I also caught them in another lie. Needless to say I won't be going back to dealerships for any work. Sick of this $h!t.

Your best bet is to email Joe. He always got back to me within hours even on the weekends. I was really surprized. I expected to get a response on the next business day but he answered my questions on a Saturday night.

Just got off the phone with Joe from Zspeed. Just as everyone said, he was very helpful. Rather than replacing the slave cylinder, I went with Joe's recommendation and I will be replacing the entire system. I ordered a new OEM master slave cylinder and the stage 1 clutch and flywheel assembly which comes with the CMAK.

https://zspeed.com/product/nissan-oe...-g37-g35s-q60/
https://zspeed.com/product/zspeed-st...clutch-system/

Prices seems reasonable and the OEM clutch master cylinder is on sale. The reputation of Zspeed on this forum, their service, and quality of parts is definitely worth the price.

I'm ordering an axle back exhaust too, because why not. I don't plan on modding my car much as it is my DD, but I'm hoping these mods will make it better than it already it is. I already called a reputable shop near me and they will be ready. This is definitely adding up to be a lot, especially since I was not expecting any of this, but I'm looking forward to it!

Thanks to all of you who helped me.

Don't forget the rjm pedal! I know Joe may say it's not necessary. Joe's clutch movement alteration kit and upgraded clutch will definitely eliminate the pedal pressure and sticking to the floor issue. But the rjm pedal makes the pedal itself feel way better and eliminated the on off feeling of the stock pedal making shifts, especially 1 to 2, buttery smooth. It's a requirement in my opinion and completes the system.

I just went through almost the exact same ordeal when my CSC went out unexpectedly, and yeah, it's a monetary doozie if you haven't planned for it. Not including the CMAK I was lucky enough to already have waiting in my parts pile, an EXEDY Stage I clutch kit with a steel flywheel, gear oil, towing and installation labor from a reputable shop came to like $2200 I think. For what it's worth, the owner of the Z-Tech (specializes in Z/G cars, and has been here for like 20 years) said the CMAK was his solution of choice and was only going by his own experience. I was quite relieved to hear that.

I expect that you're going to be as happy with the change as I was, and feel like the investment was 100% worth it when you drive the car again. Like the kit in your link, my EXEDY kit also has a 20 lb. flywheel, and the car's response is vastly improved revving it up for a down shift or just taking off from a stop. There was no loss in street driveability (is that a word?), and it now feels like a sports car and not my dad's old Wrangler while running through the gears.
I gotta agree with Joe on this one after my personal experience. With the CMAK and a properly matched single-disc clutch and flywheel, I no longer have the RJM pedal on my radar. It was just that much of an improvement.

I can put it this way: after driving the new setup for about 3 weeks, other mods will get prioritized in the budgeting department. However, since the pedal isn't too pricey and appears to be an easy DIY, I'd still give it a shot to refine things just a little more.

What and where is "z-tech"?

Sent from my SM-G965U using Tapatalk

They're a mechanic shop in Central FL that does a ton of RWD Nissan work.

I personally chose them because they were flexible with letting me choose and order the parts I wanted installed.

I'm glad to hear this! Thanks for the affirmation. I'm eager to drive my Z again ASAP, especially with the new exhaust. $2,200.00 is about what I'm looking at as well after parts and labor. I'll circle back around with my review and hopefully some pics. As for the RJM pedal, I'm sure it's very nice and I haven't put it past me, but I just don't feel like shelling out another $400 when I personally don't think I need it to fix the issue at hand.

Thanks!

I just trying to emphasize that the outcomes you were hoping to avoid were exactly the ones that were likely to occur by leaving your car with the dealer. Your experience below is exactly why we were recommending to "recuse" your car from the dealer immediately.

Smart move :tup:

Looks like you are now on the right path. Good luck with the work and hope you get back to :driving: asap
