So this afternoon I brought my N down to my local mechanic to have them put the redline mt-lv I bought. They warned against changing the fluids so soon and possibly jeapordizing my warranty. I went ahead and two things were discovered. The fluid was nearly black and absolutely full of metal shavings. Not just fine particulate on the magnetic drain plug but throughout. And then the real doozy was they noticed a bolt in the transmission was just sitting in the hole loose. I'm now sitting on hold for over an hour to get my free roadside assistance. 2020 PP manual btw.
