Nowhere does it say AWD. The W600 and the previous W500 were part time 4 wheel drive.

A 75 would have used Rockwell FDS75 (6.80:1) or Dana 70 axles (6.20:1). The transmissions were NP435 or NP540. Transfer case was a Rockwell T223

Seeing that you are in Canada, they may have used a NP201 transfer case on Canadian trucks.
