The Mobile 1 75W-90 GL-5 should be fine for the diff.

The Redline MT-90 Synthetic should be fine for your transmission. But, if you find any of the gears a bit " scratchy "  with the MT-90, you may find that the GM Friction Modified fluid is even better.

My Audi A4 Quattro with Brass sychros shifts much easier on the GM fluid than Redline MT-90 ( or Amsoil MT Fluid ). As does my 83 280ZX 5 speed ( brass synchros ) and my friends 2006 Infinity G35 Coupe with 6 speed manual. He was astounded at how much better the GM FM fluid was over the Nissan Factory fill. Just saying from personal experience...

 

 

 

Thanks!

I use what Kroon Oil here recommends and that is SAE 80  medium EP -doped single grade oil API GL-4
