Mercon VI transfer case fluid compared to GM Auto-Trac II fluid
I have a 2010 Tahoe 4X4 and the fluid recommened for the transfer case is Mercon VI , it is a single speed transfer case.
I use to own a 2006 GMC ,Envoy ,4X4, two speed trans. case., and the transfer case fluid recommended for that truck was Auto-Trac II fluid . #12378508, oil is blue in color.
It seems to me the Auto-Trac II would be better for the Tahoe .
Here is what it says on the plastic Qt. bottle.----
For four wheel drive vehicles with automatic transfer case.
Withstands extended high temperature operation.
Improved oxidation resistance.
Does any one know if this is a better quality oil than the Mercon.
I think I read somewhere it is better oil to resist corrosion of aluminum cases.

it comes from Fishers (Federated Auto), good stuff and its approved to meet or supersede pretty much any trans fluid
