2015 XP1000-4 trans/transfer case lube service

I am servicing the transmission/transfer case and the owners manual says that it takes a total of 44oz of AGL fluid. I drained about 2 quarts from the lower drain plug and when I went to fill it the at the rear fill plug the unit only took the same amount that was drained out.
The owners manual says that the capacity is 44oz. Is there something that I am missing such as a second drain plug? I have been reading that the transmission and transfer case are the same unit and the whole assembly does not appear that big to hold 44oz. Could this be a typo in the 2015 owners manual?
