Ok i stand corrected, my car was in park on level ground today. I put it in drive and sure enough, *clunk*. It was similar to when you park on a very steep hill.

I guess if it keeps doing it I'll bring it in. Its definitely a new development for me.

Here's a link to the TSB. I had this problem in my 04 Z. Don't know if you are having the same issue but it sounds like it.

TSB RA04-001b

It sounded like the rear of the vehicle. I'll try to remember to listen for it tomorrow when I go to WORK--:(

Yeah, my clunk clearly came from the rear axle. Initially I thought there was 'play' in the drivetrain, but it also happened after the car was already rolling with my foot off the brake and when I then accelerated it clunked. I was supposed to pick my car up today, but when they replaced the passenger side rear axle and CV joints, they said that now the driver-side is clunking as well, so they are swapping that one with a new Z on the lot tomorrow.

**UPDATE**
After 5 days I finally was able to pick my car up from the Nissan dealer here in Streetsboro. After swapping the passenger-side rear axle yesterday, they noticed that the driver-side rear axle has play in it as well, so they swapped that one too. My goodness, what a difference! No more clunking and also much tighter shifts. Let's hope this won't be an issue for anyone else.

I didn't notice the clunk today... So strange.

my clunk sounded like when you hit two solid metal bars together. you will definitely know when you hear it that it is not a normal sound.

I also have the same problem and the dealer is telling me the same thing. "oo its normal, dont worry about it. I had the axles greased and the sound was gone temporarily. Temp fix. I think so. I am goin back on my next oil change. Its not a normal clink. I have an AT 1st to 2nd clinks when torqued hard. Shift to rverse also clinks. This is a major problem. If you have this problem you must go to the dealer. Nissan of north america will put out a TD on the problem if it persists. But we all have to report it.

Try leaving the car in D or R, set the parking brake, then put it in P. That should eliminate that noise. Also, just a bit of driveline play may be in the diff and tranny prior to putting it in D or R. The slack disappearing could be the source of the clunk as well. Try the first thing, and see how that works. This is extremely helpful when parking at any sort of angle.

Actually try putting the car into neutral first, put the handbrake on whilst foot still on the brake then release the brake ensuring the car is stable then put it into park. This way you will not get any clunk and it is better for the tranny.
