IMO, the only difficult part about doing clutch work is putting the transmission back on the car. Working with the pressure plate / clutch / flywheel should be easy.

I don't have a Zspeed unit, so I am not sure how much assembly is required before mounting it on the trans, but perhaps one of the fittings is not properly secured to the unit and it is leaking.

Here is a link on how to bleed the clutch: http://www.the370z.com/diy-section-d...ml#post1768840

I was actually able to do it myself, by rotating between the master cylinder, to monitor fluid levels, the clutch pedal, to pump it several times, and the bleed valve to release the air, it probably took 30 minutes, not including the time to put the car on jack stands.

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?

Well after you get past the little bit of "play" in the pedal it's a little firm. And to top it off, even after a new tranny, clutch and CSC, I'm still getting the noise I had to begin with lol

Clutch sticking after tranny/clutch install: Clutch sticking after tranny/clutch install - YouTube


Here is the video I took this morning. It shows how much "play" is in the pedal and how it kinda sticks after disengaging.

After watching the video I think there is air still trapped in the system. Needs to be bled.

I'm just going to order some Motul 600 and bleed it my self. I to get out today and just drive so I can break everything in and after an hour and a half my clutch is going flat on the floor. I barely have any pressure at all and can barely put it into first gear.

Yep, either air in the system or your clutch master cylinder is going out. Luckily its not to hard of a fix for either.

*Keep an eye on your clutch fluid, make sure it isn't leaking.

Well the reservoir is full so I don't think leaking but I'm about an hour away from home and can't even drive. Will the clutch regain pressure if I let it sit for about 30-45 minutes or should I go ahead and call a rollback?

Edit: rollback is on the way. Still no clutch pressure. Nissan better have this fixed for free Monday or I'm gonna raise all kinds of hell lol and they better not and charge me a dime

My experience with Nissan dealerships is their service techs can't diagnose noises any better than a shade tree machanic. In many cases, I'd give the shade tree machanic the odds of figuring out the problem first. Thank God for this forum and others like it.

Don't know if I'd trust Nissan dealerships to work on my cars again.

Well you know the dealership is going to try to say its your aftermarket clutch that is causing the issue and isn't there fault. From everything you've said, I can almost guarantee its the master cylinder or there is a bunch of air still in the lines.

Well I'm heading up there now to talk to the stealership about it and see what say. I'll update after the verdict. They better reimburse me for the towing after they sat there and told me that the "play" in the clutch was normal and to just break it in. Also, is the master cylinder covered under warranty? And about how long should it take to replace?

Yeah, well when I had my G, the Infiniti dealership I took it to was awesome. They were the only dealership that I trusted to diagnose and do the work. Their techs we really good. But obviously Nissan is the complete opposite lol might just have to try a different Nissan stealership next time

Update: just got it back from Nissan and they re-bled the system and said that everything is good. We'll I get in the car and start to take off and there is still a little play in the clutch, it still shudders occasionally, and the clutch still sticks after disengaging just like before. I'm taking it to a different dealership this week and what they say

What a bunch of idiots, I'm SURE they charged Nissan full labor / parts for the "repair" to your car. Sorry to hear about your repeat failure. I would definitely take to another dealer. Might want to check this forum for your area of the country and ask those guys whose the best tech/Stealership in your area.

Yeah. I think I found a good stealership (at least a better one) to to take it to Monday. Hopefully they'll get this settled . I hate being with out my car...... Especially since I haven't even had it 2 months

Damn that sucks. Hope everything turns out OK!
