I would get Mitsubishi Diaqueen for the tcase and rear diff personally. Alot of guys including me run the redline cocktail for the transmissions but I wouldn't run it in my tcase or rear diff.

I've been running the Redline Shockproof in my tcase for around 5K miles over the last year at over 800hp. No complaints so far. I've got the Redline cocktail in the transmission.
