Hello everyone,

I have searched through these forums and found many 350z’s that have transmissions replaced, clutch troubles and recalls. It seems like specifically, there have been lots of problems with the 350z transmission.

I purchased my 350z brand new and have 17,000 miles on it.

When I shift from any gear, especially down shifting, it’s very hard to get the vehicle in gear, even though the clutch is fully depressed. If I don’t shift at just the correct rpm (with clutch fully depressed) I can hear my syncros grinding, or clipping. When going from a stop to first gear, it’s near impossible to shift from neutral to first gear, having to ‘force’ the car into gear.

I informed my dealership of this problem and they told me there was a recall on the slave cylinder. I left it at the dealership over night and they replaced the slave cylinder well, so they say.
As soon as I drove the vehicle off the lot it seems like the problem got even worse!

I’ve been babying my 350z and every car I have owned in the past was manual so I doubt it’s something I’ve caused. I know this is common, but as additional information, around 10k miles, when in neutral the flywheel sounds like rocks in a tin can. It was always there, but around 10k miles the noise became pronounced.
