Clutch/Slave Cylinder/ Warranty question...
I recently just hit 37K plus miles on my 2007 Z and the clutch is having that "stuck" issue that is the source of the 2007 slave cylinder recall. Eventhough my car doesn't fall within those numbers on the recall....it shows signs of this problem once in awhile. I called the dealership about it and...they told me that my warranty is already up and that it's part of "wear & tear", so i wouldn't be covered anymore. My question is... if it's the slave cylinder, then wouldn't it still be covered under the DRIVETRAIN warranty?...which is good for 50k miles? Any info would be great...thanks!
Did you look at the warranty manual that came with you car? It explains what's covered.
It doesn't really say anything about the clutch or slave, so I doubt it's going to be covered.

I was praying that it would be.

But wait, DavesZ#3... i just read this from Repair Pal Auto Repair Encyclopedia....(http://repairpal.com/clutch-slave-cylinder-replacement) it says,... "The clutch slave cylinder is directly attached to the manual transmission CASING." ---- therefore, according to the Nissan warranty info on what's covered:
TRANSMISSION AND TRANSAXLE
"CASE and all internal parts, torque converter..."
...wouldn't the slave cylinder be actually covered??

By the same argument, the clutch is inside the case as we all know, it's (virtually) never covered.
If we're going to split hairs - the clutch slave is attached to the outside, it's not internal to the case. You can change it without removing the transmisson.
I'm playing devils-advocate here. While I don't agree with the wear-n-tear argument of the dealer, it's technically not an internal part of the transmission, it's a support mechanism.
You can always contact Nissan North America and argue your case.

It's not really INSIDE the case, but you DO have to remove the transmission to get to it.
Maybe we should ask Bill Clinton. He was good at spitting hairs.

yeah..i know that was the issue with the 2007 Z's slave cylinder recall...that people had to drop off their cars for the whole day for the work to be done... because they had to get inside the tranny. The previous year 2006, it was on the outside...easier to get to.

Despite the fact that the Courtesy Parts page you linked to shows the external cylinder is used on the '03-'09 models, the design was switched to a concentric slave cylinder for the late-'06-'08 models as shown on this page:
http://www.courtesyparts.com/350z-pa...5_778_792.html
The last two figures on that page show the concentric slave cylinder for the later models. Note that they don't show a fork lever and pivot ball, both parts which would be necessary with the external cylinder.
The concentric slave cylinder is mounted around the transmission input shaft housing, between the clutch and the transmission.

That's the way I see it.
306A0+A and 306A0+B would be used on 11/2006 -07/2008 vehicles with MT A04
306A1+A and 306A2+B would be used on 07/2008 and later vehicles with MT A05 (including '09 Roadsters)
I don't see why you'd need the tube assembly (306A0+B or 306A2+B). There's not much that can go wrong with them, unless you bugger the threads somehow.
Note: The parts list clearly has the incorrect name for the 306A0+B. It should be: 350Z TUBE-CONCENTRIC SLAVE

When I hit 35K my slave went out on my 07 ... Took it to the dealer and they covered it under warrenty without any questions or problems, I don't see why they'd be givig you a hard time about it.

Well, it turns out that when i took the Z in yesterday, they couldn't even duplicate the problem.... so guess what?...they didn't even want to touch it. I noticed that the clutch gets half-way stuck once in awhile...when it's cold in the mornings when i first start it. (we're talking maybe about 4 times in the 3 years that I have the car....So my dealership's policy is that if they can't duplicate the exact problem...they're not gonna start ordering parts and breaking anything down on the car.

I can't blame them for their policy on that. The concentric slave cylinder is an iffy design in my opinion. The piston is large in diameter with a short stroke, and the compact space means the piston itself is pretty short. That's just asking for it to get a little sideways and bind in the bore, which it apparently is doing. Such a problem would be intermittent, unpredictable, and likely temperature related. I'm not surprised at the number of times this problem shows up.
As for a fix, I'd suggest either replacing the cylinder on your own or taking it apart and putting some super-good silicone lubricant on the cylinder (both the inside and outside) on the engine side of the piston.
Since it's a pretty big job just getting to the thing, you'd probably want to replace it rather than try to get away with just putting grease on it.
