Yeah it's still grinding from time to time... Not sure why yours went away. How many miles do you have on your Z?

Mine did the same thing.

Two weeks ago it stalled at a light . Felt like a manual transmission stalling when you fail a launch. The car made more noise on restart, which improved, but started making a noise in drive at idle and was not smooth.

Nissan replacing transmission now with 51k, warranty. Car has been mostly highway driven and not abused.

What did you say to them? I still feel my grind every once in awhile but I have a different transmission than you...

Not much, they could hear the noise. Nissan had them try a bunch of things, then told them to replace it after 2 days. Since the 7A is sealed, there is not much else they could do.

Have to wonder how complicated the thing is if they don't make it serviceable.
