Clutch won't come back up
 

Hello guys this past week while driving, my clutch won't come back up. it comes and goes as i drive. My fluid is a little dirty but is full I'm going to start by flushing it. Does anyone has the same issue ?

sounds like your CSC is going out

Thats the worst man I spend all day pimping air out it was endless I just gave up

Slave is dying. Common issue with the G37

Get that CSC replaced ASAP. You've got aftermarket options. If you take it to a shop, prepare yourself for a day's labor cost, because the transmission has to drop for access.

Yeah man I gave up as well I'm just taking it to a shop let's see what happens.

Yeah man I'm taking it to a shop tomorrow what brand would you recommend and how much does the job cost?

Oem is fine also change our clutch line for braided ss one

Like I already said, prepare for a full day labor cost. 8 hour job or more at $xxx/hour, plus parts. I had mine replaced under warranty 7 years ago, and it was a $1500 job at the dealership.

Research CSC elimination kit. Z1 sells one, so does ZSpeed.

Whatever you do, upgrade your clutch pedal to the RJM kit. Part of the RJM marketing claims is that it addresses the reason why the OEM CSC fails so often. So there's that, plus the fact that the clutch pedal is a pretty awesome mod.

I would recommend cmak from zspeed.

Get the CMAK from Z Speed.

Ill look it up. Can I change theithe pedal my self? And I took it to the shop the guy said he'll charge me 800 dollars for labor. But he wants to put oem parts in it and he wants to Change the clutch as well.

Is the clutch fluid low?
If not, the cause may be an internal leak in the clutch master.
When the slave cylinder leaks, it drips on the ground and the reservoir empties.

I have also read that the RJM pedal is a nice upgrade, but it doesn't prevent/reduce CSC failure according to long time Nissan expert Jim Wolfe: https://cimg0.ibsrv.net/gimg/www.myg...3786566065.jpg

An improvement on the OEM design. Nice! I didn't know about the JWT CSC.

As for the claims from RJM, note the second bullet: https://rjmperformance.com/370z-g37/

Feel free to reach out to RJM for an explanation, because I don't know what it is. Used to, but don't anymore.

If memory serves correct, the RJM pedal reduces the stoke on the CSC to prevent the chance of "over stoke" where it cracks the plastic and leaks.
If you have the money, the best solution just may be the JWT CSC and the RJM :)
