Transfer Case Fluid In Gmt 900 Autotrac?

[pckhalil]

I have a 2007 1/2 ton with the automatic transfer case, my owners manual lists Dexron VI as the recommened transfer case fluid but the dealer believes I should use the blue Autotrac II stuff. Anyone have experience with this? Are the new automatic transfer cases designed to work with Dexron VI now? Thanks!

Use Dexron VI.....Do NOT use AutoTrak II fluid.
