Like said, DO NOT use synthetic fluids with your True-trac. I dont have mine installed yet but Ill probably just run whatever GM non synthetic fluid the dealer has.

Something about how the diff won't lock properly with synthetic. You can do a search on it. Some guy's diff wouldn't lock at all, then he switched to conventional as recommended and it worked.
