clutch sticking?

phelan

i don't think it's anything to worry about either. more than that, i'm amazed you can actually tell a 'fraction of a second'.

i doubt the torque would twist the input shaft of the gearbox enough to choke a clutch either, or we have a real bad design problem on our hands when people go FI and try to launch those suckers. if anything, maybe it's just a little blip while the clutch tries to settle in to the really fast spinning flywheel.

note: i'm obviously not a mechanic, so someone with more experience speak up.

You do know your clutch is hydraulic right?

at least it wasn't the other gas pedal sticking to the floor like a toyota...

are there any drivetrain breakage prevention safety device on this machine?

This is inherent to Nissan slave cylinders; my G does the same thing. Look at it as an additional safety measure.

This happens to Corvette guys all the time. It's a Heat issue for them.

This happened to me one night one the way back from the mall.
Maybe 2 months ago?
It would get stuck and pop back up.
After I turned the car off and on it never happened again.

Never really had this problem before. Could it be due to the weather? I've never had a clutch stick the floor. I do drive my Z hard occasionally, but usually just spirited and normal driving. Could it be also that the way you drive? Maybe he drives it hard often? Either way I think thats something that should be taken to the dealer to be looked at if your not so mechanically inclined like me. Just a thought.

37Z

Nissan salve cylinders are the issue. I had the same problem swith my previousl 350Z. I swapped out the stock slave cylinder line with a SS one. In have not had this issue with my 370Z yet. I am not sure the 370Z is internal or external. Others can chime in if they know.

Firing this thread up again.. I get weird clutch action when I modulate clutch and gas e.g. merging into another lane/ getting around a stopped vehicle etc. with lots of gas, the clutch doesn't want to engage so it sits at the bottom of the throw range and sort of comes up a little if I reduce throttle- and I have to completely let off the gas (with traffic approaching from behind- fun) in order to get the clutch engaged. It's happened since I bought the car new, again today getting around a Mustang crawling over a minor RR crossing, with lots of clutch smell from the slippage. Is this just the traction control ( usually off if I remember to ) or an issue with the slave/fluid?

It's the master and/or slave cylinder. The slave is a CSC that is inside the transmission, so it needs to be dropped to replace. You can visually inspect it by prying the rubber dust cover were the clutch line meets the slave. Watch for fluid leaks.

Same here, I remember when I was driving the 350z, they had a recall on the vehicle about changing a part that is related to the slave cylinder, I have the job done at the dealership at no cost.

However, at about the 3rd year driving the 350z, I notice the 'pop' action from the clutch pedal, especially in cold weather.

Pharmacist, is your 370z still under warranty? you might want to have the service department take a look at it.

Pharmacist

haven't had any problems since i replaced the fluid with motul 5.1 it's probably heat related.

That could be it. I noticed earlier in the thread that you said it happened during normal driving....

Once you overheat brake or clutch fluid once, it's never the same and you need flush and refill the system. So you could have overheated the clutch a month before you even started noticing the issue. We stock Motul fluid, and I strongly recommend it to anyone that's going to be driving their car hard.
