I have the 6 speed and the torsion LSD.

I'm looking at doing my transmission lube and rear differential. I'm looking at
Red Line (50304) MT-90 75W-90 GL-4 for the transmission and
Red Line 57904 (75W90) GL-5 for the differential.

Would this work ok or should I just go with the GL-5 all around? Also am I correct that the transmission takes 2 quarts and the differential takes 1?

So then the fluids are the same?

I'm having trouble understanding the difference between this and this.

Is this just marketing from the company?

Yeah, I plan on buying these fluids myself in the future and having the mechanic do it, I just wanted to be sure I didn't put something where it didn't belong.

Thanks for the help, man. Solid advice as usual :)
