Bought my Z used about 2 years ago and it always had these problems:
1. Starting out in first gear it felt like the clutch was either massively slipping or something was shaking. This would only happen about 50% of the time.

2. About once a week I would be stopped at a light and when I was about to start moving I would push the clutch all the way in, but I could not shift into first gear. A quick clutch in/out would allow me to get into gear.

3. On a regular 4-5 month or so basis, I would get a p0300 code, but nothing ever seemed wrong with the car so I would just clear it and move on.

These things bothered me, but they were intermittent and small enough that I got used to them. My old 350z had many of the same issues so I thought it was normal. Many of the posts regarding judder are answered that is it IS normal.

After 3 weeks of struggling to fix a persistent p0300 code, Nissan finally replaced my flywheel. The code hasn't been back since, the clutch judder is 100% gone and I am never locked out of first gear! As the driver, the car feels SOO much smoother. :excited:

Now that I look back, the solutions seems obvious for the symptoms I was experiencing. To those who have wondered why its so difficult to engage the clutch in first properly, it may not be driver error!

Hope this is helpful, sorry if this is the wrong section.

What I'm saying is, before the flywheel swap I couldn't engage the clutch without judder, afterwards I can do it flawlessly every time. :tup:

Also, I'm not talking about shifting into first while I'm moving. I'm talking about when the car is 100% stopped -- not rolling at all.

They also cleaned the MAF sensors, replaced my air filters, and bled the clutch. (I assume you have to bleed the clutch when you replace the flywheel?)

Believe it or not, they did not replace the clutch. I wasn't super happy about that, but they said it looked brand new. (I have 20k on it)

I was VERY happy with the end result though! It is a night and day difference.

I actually have a question related to this.

When you burn your clutch, why does the car judder in 1st gear? And after couple days of use, the judder subsides.

Can anyone explain this please?
