Transfer case ID

[elite0259]

Hey everybody, I'm about to do the fluids on my 07 (GMT900) Silverado, but the haynes book has several transfer cases listed, how do I determine which I have? It has auto 4WD and it's electric, not manual.

Thanks for the help.

With the GMT 900 series they went to using Dex VI

 

Amsoil's website is a pretty good source for capacities and fluid types for various vehicles

But in the book it shows a type of transfer case that uses some gm fluid that's not transmission fluid... does that not apply for me?

This is what I found online myself...

Pg 645 it states Dexron VI for the transfer case just as txab stated. Now in the 2007 Classic yes it takes a special fluid (Auto Trak II, smurf blue).

Okay perfect thanks so much just needed confirmation that there's no way it's the auto Trac stuff
