Red Line 30504 D4 Automatic Transmission Fluid?

Saw this on Amazon and it stated it was an "exact fit" for my 2006 H3. Anyone use this in their transfer case? Getting ready to do fluid changes on my H3, getting my ducks in a row for a big purchase.

Dex VI is good stuff - maybe there's better, but my opinion is that I don't know if you will see or could measure the difference. Transmissions can be finicky so I'd stick with Dex VI spec. Others may disagree. They way I see it - a GM transmission can last 150,000 miles or more in GM Dex VI. With another spec, maybe it lasts more or maybe it fails miserably. You can do your math to figure out what's best for you.

My company gets a good discount from a local GM dealership, maybe I should just pick up some fluid there. Thanks for the reply.
