Differential and Transfer Case Fluids 2015 D-MAX

-Getting ready to change the Differential Fluids in my 2015 D-MAX. Was gonna go with the AMSOIL SEVERE GEAR 75W-90 Gear Oil for both Front and Rear Diffs. Do I have to add any additives in with it for the Differential? OR can I just use the Gear Oil alone?

-I'm also gonna change out my Transfer Case Fluid. Wanted to use Transyd for that since I'm already using it in my Transmission. Thoughts on that? Thanks in advance.
