Buh-dat-dut-dut-dut??

I was nervous too when I first got my Z, but after research here, completely normal. I'm just smoother on the clutch while crawling in 1st.

If you heard buh-DAT-dut-dut-dut, then thats normal. But if you hear DAT-DUH-DAT-DAT-KA-BOOM!, then thats not normal

Sounds like clutch chatter OR....

You might have these things too close to the ground...

I just might become so concerned that I spill my scalding coffee in my lap!

Seriously though..it's likely that I would not be able to reproduce that one for you all to hear!

Unloading the drivetrain like that, I got a clunk in my old Z, too. Especially if you are coasting to a stop in 2nd and let the RPM dip really low before you disengage the clutch quickly, you will hear it.

When the car is good and hot, I hear some kind of chattering if I try to take off gently/don't give it enough gas when I let the clutch out which I understand is "normal" too.

Finally, if I am crawling along in 2nd at 1500rpm and gently step on the gas I hear what sounds like a quieter version of the clutch chatter, also only when hot. Although it almost sounds like an exhaust leak, I think it's very faint chatter.

I can't reproduce either of those last two on a quick drive when it's cold, I have to take it out and get it really hot, drive it for an hour, etc.

Never heard either of those on my 350Z, but I've seen people describe those as "normal" too.

These transmissions are just noisy I guess.

yeah Happy, I think I have heard that (form of it) before. I think it also happens when crawling from a stop in 1st or 2nd, and releasing the clutch too quickly. I believe I responded to a thread on this some time in the past.
