There is a debate on the French forums for the use of the motul gear 300 for tranny. People strongly advise against Motul gear 300 it because of the GL4 / GL5 mention.
I trust this forum the370 more than french forum, we have very few nissan 370z. People living on the North American have more experience on japan cars.

But I don't use motul for tranny because it will be difficult to sell later if I use this oil

If 75W90 viscosity is Ok, I will try Castol oil for trann (unless the redline MT85 will be back)
