I am down to my final fluid change in my 2011 Cadillac CTS AWD with 75500 miles with a 3.0 engine as I have had the transmission and transfer case fluids changed over the past month. Is the differential fluid something you change in every car or unique to AWD cars? Is it something any shop can do or should I have the dealership do it?

Also what does this fluid do?
