[V8] Manual gear oil (transmission)

[too many quattros]

the 75W90 NS must be a newer one.  when i called Redline a couple years ago,
they told me not to use their 75W90, this one,

in a gearbox.  

i wonder how the 75W90 NS differs from the MT-90, which is also a 75W90?
other than the fact that the NS is a GL5 and the MT is a GL4.
