Winter is coming and I will be doing upgrades and repairs, might as well beef up CSC while at it.

Just fix it right

I guess last night I joined this unfortunate club. Clutch fluid was below min a week ago. Did a flush and replaced the fluid. The clutch was better for a day or 2 but then started losing pressure. Last night it abruptly lost all pressure and I was not able to get it into gear. Clutch just sticks to the floor. While there are no visible leaks my break fluid was below min a week ago, and the leak may be inside the bell housing.

Looking to pick these up from Jie at ZSpeed:

Should I replace both CSC and cmc at the same time to save on labour? If they will both eventually fail anyways...

eastwest2300 · 12-05-2018, 09:44 PM

yes, replace both at the same

Joining the party... same symptoms, same solutions. Question is Zspeed ezstreet stage 2 or 3 quiet, or South Bend Stage 3? Already ordered the RJM Tilton pedal kit. CMAK is a given.

You dont need stage 3 if you are not boosted or planning on boost. If you are boosted or really beat the crap out of it, Track, Drag, Time Attack etc you may want to go with the Stage 3 or contact me for the Stage 2+ kit we also offer (not on new site at the moment)

EZ Street is good for just about everything but more for a daily driver, normal hard driver type work and is our most popular, comfortable kit for mixed use.

+1 for Joe at ZSpeed!

After two failed stock CSC units from the dealership within a year, I talked with Joe and got his heave duty CSC unit. That was back in early 2015. When the second one went out, Nissan installed a new master cylinder and I talked them into installing the heavy duty CSC instead of yet another OEM unit. I have had ZERO problems since! I dont track and its a daily driver. I have only flushed the fluid once vs every 3 months with the OEM garbage. I also removed the clutch pedal spring because I hated how it masked the feeling of the hydraulic system.

Joe did this replacement right! Even the Nissan tech told me that he has never felt a clutch feel so good in these cars after they test drove it! What does that tell ya?

Keep up the great products ZSpeed!

Can anyone recommend a mechanic or shop to replace a CSC and clutch in San Diego? It seems that most shops to get this type of work done other than the dealership in my area is in LA

I googled nearby transmission shops and drove around until I found one with a pristine rebuilt '57 Chevy and other such cars out front... figure someone who puts that much into a car would take it somewhere they trust.

So mine failed a couple of months ago. only 26k on it. i asked them if i got my own csc if they would install it under warranty. they said no

i talked to them about others having the same problems even with newer cars and said i didn't want the same cheap part. the only thing they could tell me is it had a new part # and that usually means something changed. maybe they upgraded it? i had no choice i had to let them fix it. i just couldn't afford to not have it fixed under warranty.

If under warranty. Let them have the headache of fixing it.

If you live in California, you may be able to join the class action lawsuit against Nissan if you experience shifting problems, or if your CSC failed:
