Default Need help with a clutch problem!!

So here is my dilemma. I bought a 2011 370z nismo about 2 months ago. The car has 22k miles on it. I started to hear a knocking sound coming from under the car so I took it to the Nissan dealer to get looked at under warranty. They say they couldn't exactly pin point the problem but it sounds like the transmission. So they replace my transmission. While they're doing that I ordered a southbend stage 2 daily clutch, Zspeed CSC replacement, and SS clutch hose to be installed while tranny was out. I pick my car up this morning and notice that the clutch is sticking. It doesn't stick while engaged but as I'm depressing the clutch it sticks at the top and I have to pull it up with my foot. Idk if it will go away when it starts to get broke in or what. If anyone could give me some input it would be greatly appreciated. I searched the forum but couldn't really find an answer.

I would take it back, I think they may have screwed something up putting it in.

^also, when I start to take off, the car studders at around 1500 rpm like it wants to stall out. Don't know if that's normal with a new clutch/tranny

Nope, not normal at all. I had the same clutch installed and it felt just like stock even during the break in cycle. There could possibly be air in the system. Sometimes our clutch system can be tricky when bleeding. As for the dealership installing the clutch wrong.... well it only goes in one way so I have no idea how you could screw that up. I would say re-bleed the clutch line and go from there. It would have been a good idea to replace the master cylinder as well.

Yeah, I'm taking it back in the morning after work. After the install of the aftermarket parts it voids my warranty but if they messed up they better fix it for free

I had my dealer do a aftermarket clutch, had problems with the stock, but replace OE CSC and they took care of the labour...
As MJB mention the clutch is in right, it's most likely an adjustment/bleed that is needed. If the Master wasn't done at the same time I would also do it, after going through 3 of each, if you do one, do the other. the master is cheap.

As far as the dealer putting in the clutch, I just tried to kill 2 birds with one stone (and they didn't charge me labor to do it). But going to see if bleeding it helps. Mine definitely doesn't feel like stock. My clutch practically engaged when I pushed the pedal but now it doesn't engage till half way through the pedal. There is barely any engagement room.

Well like I mentioned, I'm gonna take it to them in the morning and tell them to bleed the system and if that doesn't work then tell them to re-adjust it. As far as the master cylinder, going to look in to that. Might as well go ahead and do it right the first time

Update: Nissan says that every thing was bled properly that the instructions for the Southbend clutch say to let it get broke in before you get the original clutch feel back. Is this true? I didn't see the instructions sheet

Perhaps you should bleed it yourself. The clutch not coming back to the top seems like a hydraulics issue, not a clutch disk issue. That, or they screwed up the install of the CSC.

I put a flywheel on a few weeks ago and completely emptied the clutch fluid, even squeezed it out of the CSC. After a proper bleeding, it works like it is supposed to.

Did you get your car back from the dealership? How's the clutch feel. Your car shouldn't shutter with the new clutch during the 500mile break in process. Like I said, I had the exact same clutch and it felt just like stock, no shuttering or pedal issues. I just recently installed a JWT clutch myself and same deal, no issues.

I haven't searched yet, but is there a DIY to bleed the clutch? And how exactly could they have screwed up the CSC install?

Well I didn't even drop it off. I went by this morning after work and talked to the technician and he's the one that told me that it just needs to be broke in and that it showed the clutch was properly bled. "aszyd" ^ says they could've messed up the CSC install. Could that be the case? He also told me that is was a PITA to get the clutch installed. They told me to drive it for a couple weeks/ couple hundred miles and see if it doesn't resolve itself.

The car shouldn't shutter on take off just because its a new clutch. A brand new car doesn't do that, and its clutch needs break in time as well.

I don't see how they could mess up the CSC install. It only goes in one way. A clutch system is not complicated at all, anyone could do it with the right tools. Just tons of work to get to it. Hows the pedal feel? Spongy, soft, or is it firm?
