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

Neptune · 09-12-2012, 06:27 PM

Dealer replaced the slave and master cylinder and paid for my rental! clutch feels a lot better and smoother then before.

Good luck even if they replace it. Joe at Zspeed illustrated their poor engineering along with Zspeed's corrections. What they did "just made sense."

Mine is finally going in Friday.

got mine back today -- clutch feels great.. put about 200m on it after picking it up.

Mine is the clutch master cylinder. Part will be here in one week. Covered under EXTENDED warranty. 41k miles.

Work order states " Customer states clutch pedal fades and feels mushy when 1st applied at cold start". Inspection confirms customer concern. Mushy feel and found the fluid is full, the clutch master cylinder is by passing. Suggest replace and recheck clutch function.

Next week we will see...

All mine needed was the clutch master cylinder (cmc). 1k + mi on cmc and no worries. Wonder why dealers are replacing the csc if it might just be the cmc. Warranty $$ maybe....unless as someone previously stated the clutch is being thrashed.

All good here, but will keep a foot out for csc.

That should help. IIRC, failed master would lead to failed CSC. I had a buddy with a G370 who had the CSC replaced 3 times before they realized it was the master cylinder that needed replacement.

Can you explain how/why a failed master would cause failure of the slave? If slave is not disengaging properly, wouldn't the damage be more so trans related (syncros and what not) than CSC?

Fingers crossed that by replacing the master clutch cylinder will save the CSC.

how do I get this checked? any signs too look out for?

DIGItonium · 09-15-2012, 05:05 PM

This stuff is way over my head, but the CSC kept failing in his car before they replaced the master cylinder.

fosingwo · 09-21-2012, 11:33 PM

how many time does the same part have to be fix for it to be considered a lemon?

SS_Firehawk · 09-22-2012, 10:43 AM

I remember seeing a revised Nissan OEM CSC, but when did they start putting them on their cars?

afbunn · 09-25-2012, 09:52 PM

Bump for this, my car is in the shop right now for these same reasons. Mechanic says it's the slave cylinder. We have to order the part since we're on Guam

and after what I've been reading in this thread, should I tell him to go ahead and order and replace the master cylinder as well while he's at it?

40k Miles 09 370z

Clutch Pedal stuck to the floor, towed to the dealer. Dealer wants 1600 to replace the clutch assembly and are checking out the slave cylinder and flywheel. I have the extended waranty.

After reading all this I wonder if my cluch assembly even needs replacement and I just need the Master/slave cylinder replaced. ( I don't know much about cars)
