Nissan 370Z Forum - View Single Post - is there anyone okay with your 370Z after 100K miles without ATF change?

I did read the maintenance guide. It said the 370Z's automatic transmission is maintenance free.

I really get confused here. Now I'm using my second Nissan genuine automatic transmission on my 370Z. I got it installed after its fluid had been changed when around hitting 100K miles and was soon broken after that ATF replacement. (it was a Nissan genuine AT fluid of course, because I got service at a Nissan dealership).

It does not mean that changing fluid surely did break it. I got my 370Z as a pre-owned one, and have no idea about what exactly its previous owners had put into it. (If in case they had put any third party ATF, then it might not be maintenance free, right?) - or it just unfortunately might be classified as a 'defect'.

Anyway I really do not want to see my transmission broken again. I want to keep my Z as long as possible even after I buy another car in the future. My dealership recommends me to get it checked everytime I take the oil change and replace its AT fluid basically every 100K miles.

I don't go to the track, and consider myself as a just normal daily driver with some rare spirited driving that I enjoy my zero to sixty when I enter to the freeway.

So, is there anyone in this forum okay with your automatic transmission without changing its fluid even after 100~200 miles? Is its fluid literally 'ever-lasting' as maintenance free? I've done pretty much research for this by myself, but still cannot make my decision.
