MotorcraftXT10QLVC Mercon Lv Automatic Transmission Fluid

Ford says this replaces the old part number xl-12? Also can this be used in the transfer case of a 2000 f250 with the 4r100 transmission ?

There is another motorcraft LV for 11.99, why is this? is one counterfeit?

So why is Amazon stating this is the wrong transmission oil for my 99 f350 v10?

Will this work for my 2011 ford focus SE 2.0 automatic transmission
