Does my 2008 CX-9 FWD have a PTU/Transfer case?

I’m new to this forum. I have a 2008 Mazda CX9 that is FWD and I did a transmission flush. But I am wanting to know do I have a Power Transfer Unit (PTU) or transfer case or is that only on AWD models? I’m asking because I’m wanting to do a fluid change on that as well if I even have that on my FWD model
