If you mean it makes the noise only when letting the clutch out, my 99 SE has done this since new. I remember querying at the time and it seemed to be a general consensus that this was "normal" on the Maxima, possibly a design flaw, but nothing that shortened the lifespan of the clutch or caused any harm (outside of general embarassment).
So, I totally ignored it, still do to this day, and after 120,000 miles
the original clutch still makes the same noise but still runs (or rather grabs, in this case) like new. I've had absolutely zero problems, slippage, or otherwise. In fact, it's been a great car altogether!
Not to steal this thread, but how loud is the trans when you let out the clutch and the car is in neutral? On a scale of 1-10 where 1 = can't hear it and 10 = same loudness as the exhaust. On my 91, it whines at least a 10 and multiple mechs have said it needs a new transmission. The previous owner said it has been doing this for that last 100k and there's 185K on it now. Still original clutch and I notice no driveability issues, just that annoying sound.
TIA,
Derek
