Drivetrain Fluids

[2012M37x]

Hello,

My first post here, was on a board for our G37 coupe when we owned it but frankly my M37x has been so reliable I haven't joined anything until now. I have a 2012 M37x with 83k miles, I'm the original owner. I was looking in the maintenance booklet trying to find info on transmission, differential and transfer case fluid/oil changes. Only thing I could find was regarding the transmission fluid at 30k mile intervals but it would say *except 7 speed AT transmission (which I have). So, what are the Nissan recommended fluid change intervals for:

Transmission (7 speed AT)?
Front and Rear Differentials?
Transfer Case?

Thanks!

The 7-speeds all take Matic S, that's an upgraded Matic J with extra friction modifiers specifically for the 7's. These are the fluids I know to be compatible (there may be many others):
AMSoil Signature Series Synthetic ATF
AMSOIL OE Fuel-Efficient Synthetic ATF
BG Universal Synthetic ATF
Castrol Transmax full synthetic
Red Line Synthetic D6 ATF
Valvoline Maxlife ATF

The transfer takes Matic J, the front diff takes GL-5 80W-90, the rear diff takes GL-5 75W-90. We have the factory manual for your ride here in Nico, you can find the fluids on MA-16 here:
