2004 Tacoma transfer case fluid

I’ve been trying to figure out what the best transfer case fluid is for my 2004 3.4 automatic Tacoma. Wondering if anyone had any suggestions

 

Redline makes good stuff.
If you one of the "best", they are in that category.

TRANSFER Oil capacity,
L (qt., Imp. qt.): 1.0 (1.1, 0.9)

Oil type: Gear Oil API GL−4 or GL−5
Recommended oil viscosity: SAE 75W−90

 

I used Redline MT90 GL4.

 

I use 75-90 synthetic. I can't remember the brand name right now.

 

I also use Redline for the transfer case and the front and rear diff in my 2011. I used Redline in my Miata transmission and diff for years when I had it.
