Has anyone ever used this in a GM transfer case calling for Auto Trac II fluid? If so, please share your experience. Thanks.

Valvoline says it meets the need...

If Valvoline says it is compatible/ok to use then it should be ok. I have used it in GM AWD transfer cases (NP149) with no issues.
 
Mind you, their maxlife says its compatible with AT2 as well. I'm running a group 4 atf in my AT2 with no issues for close to 3 years.
