Have three of these for biz, diff years. In the past, have always used (as told) the auto trak2 transfer case fluid for a drain and fill of the transfer case. Noticing for my new 2011, manual says to use Dexron Auto trans fluid.

Is this new? Have a gallon of the auto trak 2 left. Can I use or no?

 

no. The fluids have different co-efficient of friction. do not use the wrong fluid or your risk damaging the friction material of the clutch packs.
