is there anyone okay with your 370Z after 100K miles without ATF change?

While there is a bit of truth to the don't-change-if-miles-are-high theory (mainly with older ATs), it's not gospel. Depends on the lube and what's being lubed. With modern ATs/ATFs, it shouldn't be a problem.

You know, not all modern automatic transmissions are maintenance-free.

I actually somewhat agree to that no-change-at-high-miles theory because in my experience my Z got pretty faster acceleration (like having higher torque) just after its ATF change at around 100K miles, but soon some weeks later after all it got broken.

I guess that previous transmission must have malfunctioned after its fluid change anyway ..
