I have searched on some forum and web, I know that the slave cylinder will be bad very often. But it seems like to be an easy fix for me.
My big concern here is I saw a post saying that there's also a problem with the clutch slave cylinder inside the tranny. Is it just have a few amounts of people who have this problem or it will turn bad very often?
And is there any other problem with the tranny in 2007 350z?

 

i had to replace 2 oem's.... others have replaced zero.. kind of luck of the draw

 

Welcome- the CSC is a known issue with the '07-08 Z. Other than that, you have the latest version of the 6-speed tranny, so with proper lubricants and regular maintenance, should be good.

 

let me rephrase, i have replaced 2 oem slave cylinders, and one master

 

I had to replace none. Because daily driven 5AT
