I believe the Escalade has AWD which means it's always giving power to all 4 wheels. 4WD is what the Tahoe has, where you can select between 2WD and 4WD. If you have the 2nd knob with the 2 low, auto, 4 low & 4 high next to the headlight knob, you have a 4WD vehicle and it SHOULD take Auto Track II fluid. You can always call the parts department at your local dealer and give them your VIN and they will tell you what fluids you are supposed to use.
If the fluid was blue when you drained it it's Auto Trak II.
