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

FairladyZ10PG · 07-27-2015, 03:16 PM

Just a thought, before my CSC gave out my car had problem starting. So I often had to depress the clutch pedal very hard several times before the car would start, which I believe led to CSC failure.

I think if I hadn't stomped on the clutch so many times the CSC might not have failed when it had.

does anyone know the ratio or percentage(if one is needed) needed for a recall to be issued. so far 90 cars out of tens of thousands sold doesn't seem like a high percentage of cars having a default.

Good question, I would like to know that too. We might be missing a lot of the G37s and people with Z34s that had this issue and a)are not in this forum b)fixed it and didn't report it c)had the issue and its not documented.

Could be, but I'm no mechanic. There are two sensors at your clutch pedal that I know of, 1 for cruise control & 1 for starting vehicle. If you should happen to have difficulty again with starting, I think it may just require a minor adjustment at the pedal. There was a link with pictures on the370z.com that explained how to make adjustments for those sensors. If it were Me, I'd take it to a shop to make adjustments because it is a pain in the a** to lay on my back with my head up under the dash.

I think it takes some serious injuries & or deaths before anyone takes recall action. Basically Nissan doesn't give a SH*T !

About a year ago my clutch PEDAL broke, shearing off the helper spring mount. The pedal became very sloppy and difficult to shift but I replaced it with the RJM adjustable pedal and was very pleased with the results. Thanks to this website though I have since known to keep a close eye out for any CSC issues.

The car is my daily driver and I generally baby the car around town, although I have been to a few HPDEs with it. I currently run PFC 665 for the clutch line.Two weeks ago while changing my engine oil, I noticed that the Clutch reservoir fluid level was getting very low

. Prior to this, I had not had any problems with the clutch line and had it flushed at least once before. No puddles or leaks were noticed under the car or on the bottom of the transmission. I ordered the ZSpeed CSC and parked my car for a week (make sure you have a spare car if you own a nissan or anything British).

I am lucky enough to have a good friend that owns a shop with a lift, and today the two of us swapped out the CSC. The entire procedure took roughly 3 hours, and was made much easier by slightly dropping the front subframe to help tilt the transmission down. The clutch disc was noted to be plenty thick still - which is great since I didn't order a new one. Car is now doing great although the engagement point is slightly lower and grabbier, two things I can adjust with the RJM pedal.

Before I did the work myself I went to a Z shop locally and was quoted roughly $950 labour + parts. I ended up doing it myself with a friend for the price of the CSC and a few good beers (Dogfish Head, Aviator, and DuClaw).

As much as I love this car, I will say that I have been pretty disappointed by the build quality and random issues I've had - breaking clutch pedal, CSC failure, axle click, engine oil overheating, and clear coat bubbling off all over.

It looks like you are the first I have seen who has had spoken up about a CSC failure after RJM pedal install. How long have you had the pedal installed until your failure?

Yes the car is back in my hands after staying at the shop over the weekend.

The most likely culprit was the 5 year old battery that I had in my car, so the battery has been replaced and the sensors and pedals have been adjusted. The car is starting like new again

well fellas, I got my Z back from AAM, I drove it a good 40 miles in DC traffic, she drove very well, Im happy.

Good job by AAM.

eastwest2300 · 07-27-2015, 07:45 PM

Oh I forgot to mention, I did NOT have a CSC failure or any sort of mechanical problem.

I have a 2010 with 8000 miles, I only replaced the CSC with the zspeed HD CSC as a preventative measure. I also went with a Southbend Stage 2 clutch, a Southbend billet flywheel, a new CMC, and a stainless steel clutch line.

Running redline fluid in the trans case, and RBF600 in the clutch reservoir.

I also just got my RJM in the mail today.. I'll be doing the install some time this week.

MagmaRed370z · 07-29-2015, 11:09 AM

Happy that I am changing my CSC to HD CSC from Zspeed next month. As a preventable item. Peace of mind all the way!

Blighter · 07-29-2015, 11:46 AM

Just swapped my fluid with some of the RBF 600 stuff.

I have never had a CSC issue but I am monitoring the fluid weekly. I DD my car. No sure if the previous owner had an issue. car has 27k
