I finally got my redline fluid in two days ago. I changed the fluid today. I drained the GL-5 fluid out and then I used some standard ATF to clean out the gear oil. I ran the car a little while at idle, in forward and reverse gears to circulate and mix with any remaining GL-5 fluid. Then I drained that too.
Afterwards I added about 2.5 quarts of Redline MTL. It sort of smells like a gear oil but is thinner, almost like ATF. However it feels much more...oily I guess, slicker than standard ATF.
Now I have noticed that the transmission sounds the same as with the GL-5 fluid, that is to say QUIET!
With the ATF+ 2oz of FM in it it was noisy and sounded like it was grinding away. When I drained the ATF there was a fine metalic sheen to it from hard part wear though it was a new diff so that is going to happen anyway.
Anyway, the fluid is the correct type and so far I still do not hear any noise so I feel really good now.

Ok, I spoke too soon.
I do hear the noises again now that I have had the fluid in there for two days. I am really bummed.
I went about 10 days with the synthetic GL-5 fluid and I didn't hear anything, now with the MTL I am starting to hear the same groaning noises in tight turns.
The high pressure additives in the GL-5 really made a difference I guess, but the MTL looks and felt pretty good.
Why is it making noise now? It is not as bad as with standard ATF, but I'm going to give it a couple of days of city driving to be sure of a fair comparison. Then if it still makes noises I'm gonna start getting pissed off and calling Torsen about the unit.
You can't actually blame the install because if it was done improperly it would make noise in straight-line driving. Only having noise in tight turns with a recommended fluid indicates it is something internal within the diff. The fact that it was fine with GL-5 fluid makes me even more suspicious.

What do you experts think about this???
