The only thing I can think of is if you are trying to make Andretti stops on the street? The ECU will use DRM to assist in engine braking as well as braking in order to give you more controlled and quicker stops. Sometimes my AT makes lil noises but I ignore most of them unless they cause some type of abnormal NVH. Nissans are loaded with tech that are always helping you do something. Occasionally you will hear them.

Also, I'm going to strongly go with you are also feeling ABS. That's it. Nothing more!!

I'm not feeling ABS. 100% sure of that. I'm not braking hard enough for ABS to kick in.

I agree. I feel the same thing. I have over 35k miles so far and everything is fine, so I just quit worrying. I still think it has to do with the difference in transmission connection in 1-2 gear. I believe it's "liquid"(could be wrong) and the rest are solid connections.

iv'e never had that problem. if you trust your dealer take it in for a check.
have someone ride with you... they will probably say it's normal but it's not....
but at the least you have it documented. if it does get serious.

I don't trust the dealer because like you said....they will say it's normal so I rather ask the more knowledgeable guys here. I didn't think this was normal but since others have claimed that their Z does the same I don't feel as worried anymore. Can others who have an automatic Z please chime in. Are you sure you don't feel any hard downshifts especially 2nd to 1st?

I wouldn't call it a hard down shift.
if your asking can I feel it than yes
but no way a hard shift. I would still
have it documented at the dealer to be safe
