From the research I've done, a lot of people are running Redline MT90 in their transmission. I have also used it in the past and literally just filled my transmission up with it. As for the rear differential, I've found that Redline Heavy Shockproof Gear Oil is a popular choice (transfer case as well). Of course people are going to have varying opinions, but I jumped on the bandwagon and have been happy so far.
 
Redline MT-90

And redline heavyweight shockproof in the transfer case and diff. Ive found it to be a little notchy in temps under 50, but after the first couple shifts its fine.
 
Sweet great info and how many quarts do I need for the tranny, diff, and transfer case?

There is no need to mix Redline oils anymore. Here's what you need:

Red Line Synthetic Oil - Gear Oil for Manual Transmissions - MT-85 75W85 GL-4 Gear Oil

I recommend Shockproof Heavy in the TC and 75w/90 in the rear diff.

You say you recommend shockproof heavy for the tc but not the shockproof heavy for the rear diff and just use the 75W90 NS GL-5 Gear Oil for the rear diff, why not just shockproof heavy in the rear diff? Just making sure thats what you where saying.
