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

TacoSport10

So the stealership is saying my pressure plate is likely gone as there is no leaking fluid, and after sitting for several days they were able to move the car and out in gear.

They quoted me $2,900 for OEM so I’m looking at going with the Zspeed stage 2 with CMAK csc delete. This would also upgrade my csc and I’m going to replace the cmc while I’m at it. Only thing is I’m not sure about going to a solid flywheel vs dual.

Joe@ZSpeed

You will get a little added noise with the solid but it will drive much much better than the dual mass as well as add a good amount of performance.

Thanks Joe! You’ll see my order tomorrow or as soon as those sales start for Black Friday!

Shout out to Joe@Zspeed as I ordered my parts this Thursday and he shipped on Friday. I just got them in today, yes a Sunday, and will deliver to dealership tomorrow. Hope to have my car back Tuesday or Wednesday.

Thanks Joe, you got yourself a future customer in me for sure!

Joe@ZSpeed

You have it all installed now that it's Monday, right?

HaHa, I wish!

Dropped it off at the dealership this morning. They're getting to it either tomorrow or Wednesday. I don't have the tools and lift to get this done.

Just got my car back! WHAT A DIFFERENCE.

I can tell now how much my old clutch was slipping.

I also had times where my rev match would shoot up when I engaged the clutch but didn't change gears yet. Reading the other night it sounds like that's another sign of the clutch slipping.

I'm taking it easy for the first 500 miles or so, but it's night and day so far.

The technician at the dealership was also VERY impressed with ZSpeed's kit and CMAK.

Anyone know if the CSC issue was fixed on later model 370's? Haven't been able to find a solid answer yet. I've got a 2019.

Rusty

Nope. Still using the same old parts.

Terrific.

ZSpeed replacement CSC. Buy one. When the inevitable happens, you can have this one installed instead of the faulty OEM unit. It's an all metal unit and now they sell a kit that includes a new master cylinder. When the CSC fails, it contaminates the fluid which can compromise the master so it's always recommended to change both at the same time. I've had this on my car for 6 years and never had any problems. Clutche is rock solid, 100% predictable, and my fluid has never gotten dirty or contaminated since. The Nissan tech that installed it said that he's never felt a clutch feel so good in one of these cars before. Lol

You can add me to the victims list. I have a 2015 with 15k on the odometer.

Pretty much the exact same story as everyone else. Luckily, I researched prior to having the dealership do anything (thanks to this forum of course). Long story short, I had Nissan replace the fluid, and bleed the line, which obviously didn’t work. They wanted like $2,500 to replace the usual suspects, and he probably added a bunch of things to inflate the bill. I don’t remember, because I wasn’t even listening at that point. I had no intentions of having them do the work, even if the CSC they were replacing it with was a good part, and not made of plastic.

I went through the Nissan complaints/claims process, to no avail. Has anyone ever won one of those battles, and gotten their bill covered for csc/cmc failure, out of warranty? It looks like no, but figured it’s worth asking. I ended up getting the JWT CSC, and OEM master replaced by a 370z mechanic who knew the problem well. It was 1,170 total ($420 for parts $750 for labor). The car is running great. It feels like I’m learning how to drive stick again, because of how soft the clutch became before failing. I had forgotten how high the engagement point was. Is there any harm to removing the assist spring, that I keep reading about?

Basically Nissan is handing everyone who purchases the Z, a bill for 1-2k, before even driving it home. What makes me sick, is they still use the exact same part to this day. I’m a soured with Nissan for good. I would think it would be less expensive to fix the problem and make whole the people who were screwed, than to lose so many loyal Z enthusiasts. When the next Z comes out, we are all going to be thinking, “Okay, what sh!tty part is going to go bad in this car.” And we will 100% know that Nissan will do whatever is in their power to screw you, instead of help. It’s saddening to me.

My Zspeed HD CSC just failed after just changing it last year. Probably gonna bite the bullet and get the CMAK this time.

JARblue

That's unusual. Are you sure it isn't just the master cylinder?

Hopefully. I haven't looked into it yet. Just the pedal to the floor symptom.

Edit: Great news! It was just the clutch hose ripped off at the crimp. I would've upgraded to stainless but wanted it back on the road asap so maybe another time.
