Finally got a purchase survey and made sure to note this issue there, as well.

Dude, your CSC failed twice? So you had it fail, you replaced it, then failed again, you replaced it, then the 3rd time you got the one from Zspeed? Am I understanding this correctly?

The previous owner replaced it. When I bought car it came with receipts from Nissan dealership. It busted on them at about 40,000 miles ( I'll have to check receipt for actual mileage)

Then it broke on me just a little past 60,000 miles. Crazy too how it happened; I just started car, let it warmup & high idle drop, put in gear went about 40-50 feet at 5-10mph in complex garage. Then pedal just dropped.

I understand this might not make too much mechanical sense, but I was just curious to know how many of you had the csc failure with the RJM clutch pedal?

thats a good question, im not really sure, but I would say this, An aftermarket pedal and the actual csc are two entirely different components, that pedal wont save that poorly made csc.

Honestly I was totally unaware of any CSC issues with 370z. In fact, when I was looking at the car (prior to purchase) the previous owner nonchalantly mentioned replacing CSC do to it having "a leak" . Me being naive, thought nothing of it. I thought "a leak? that's no big deal"... How wrong I was!

Why didn't the previous owner put an aftermarket one in? I'm sure he was likely NOT a car guy.:ugh:

LOL yeah. I wonder what the mechanics, engineers and board of directors at Nissan think about: "Oh we put a very important transmission plastic part inside the 370z that was recalled in the 350z?" That's not good....:ugh2:

This thread has a lot of info on the RJM pedal: http://www.the370z.com/drivetrain-en...el-stroke.html

The RJM pedal does put less strain on the CSC than the OEM pedal. Ryan explains it in more detail in Post #176 here: http://www.the370z.com/drivetrain-en...ml#post2566457

johnwiki 07-15-2015 08:09 PM

My clutch just went out for the fourth time. The first three times they replaced the slave, the master, and the clutchline in that order. Now they said its the clutch itself and are replacing the cluthplate, pressure plate, and the flywheel.

Tell them to replace the CSC with a Zspeed one and a new OEM CMC. Problem solved.

Mahalo JAR! I hope Ryan's correct as I've had his clutch pedal in my car for nearly the life of my car. However anyone who has had an RJM clutch pedal and csc went bad, please feel free to chime in.

I can tell you from experience that it is pretty $hitty working under the dash like that. So make sure you review the details of the install thoroughly before you even begin. I took breaks every 10-15 min I spent under the dash. Basically, I would do a few steps under the dash, and then a few steps at the work bench.

There are two things you can do to make working conditions a little easier and more comfortable. First is remove the driver side seat - I think it's only like four bolts although I didn't bother to do this. The second thing is to find something level with the door sill that you can lay on top of. I set a 2-drawer wooden filing cabinet on its side and covered it with a blanket so I could shove it up next to the car. You can use a pillow or two for extra comfort if you wish.

Roger that, thanks man! Good stuff.

KoolKarmaJoe 07-16-2015 09:51 AM

Any difficulty with "cruise control sensor" or "start sensor" when putting in new clutch pedal assembly ? Any helpful hints?

That is one reason i haven't bought one sooner.I work on cars for a living and i hate doing under dash work.I didn't even like putting in the softer assist spring.

Yeah dude, its gonna suck, I already know..

Magic Bus 07-16-2015 04:16 PM

JAR's correct guys, you've got to be a contortionist to work on the clutch pedal. I'm of slender built and it was a bitch staying under there for 10 minutes. Never removed my drivers seat or did I put something level with the door but I think that's a great idea.

Interested to see if this occurred as well.

Haha, I was asking myself the same thing when I was installing it.

I think the cost and hassle of installing the RJM pedal was worth it and if it keeps my csc from going, then it's worth 5 times the cost, literally :tup:

Oh yeah, one last thing, I'm never going back under there to remove it when I sell the Z, no way, uh uh :icon17:

Yep. They hooked me up though and replaced the slave since the nissan parts warranty was almost up on it. But the thing is its happened to me so many times that even though the entire clutch has been rebuilt I still dont feel confident that its fixed. I still feel like any second now im gonna feel the clutch hit the floor again. I guess what makes me nervous is that the clutch pressure is still inconsistent. The engagement point stays the same, but the force required to push it is slightly different sometimes. Reading around the forum some people say its normal for the Z, can anyone comment on that?

I would feel the same way as you!

I have been a victim of my clutch pedal losing all pressure and going down to the floor. This has happened to me twice now. The first time one dealer replaced my clutch fluid and with "Gtr fluid" and did some "clutch adjustments". That was supposed to fix the problem.
Three weeks later my clutch pedal is back on the floor. I have it at another dealer since my car broke down out of state. They fixed the problem the same way as the first dealer by bleeding the clutch fluid. I told them that was how my car was fixed the first time and I am scared it will happen again. They said they will look further at it and see if the they can find why this is happening. Can somebody give me some information on what they should look at specifically? If they can't find the issue, I think I will sell my Z.
I really do not want to but I need to be able to drive my car with confidence.

This issue is the $hitty OEM CSC. No question. The stupid GT-R fluid solution the dealers are using is just a band-aid for a broken leg :shakes head:

I drive my Z all over Texas and often times to locations with little to no cell service and zero traffic on the roads. So I replaced my CSC with one of the aftermarket solutions before it failed and stranded me out in the middle of nowhere :twocents:

Thank you. It is a shame Nissan and their dealers are aware of this issue but act like it does not exist. There is no way they have not heard of this issue. How is it I can come to this group and get information on it, yet they suggest these band-aid solutions. I will file a complaint with the NHTSA that was provided on the first page of this thread.
