I call BS on this. I have attached pics from the Australian Mitsubishi web site of the PDF for the 2018 EC service regimen. It states transmission at 90,000km for normal usage and 45,000km for severe (same for the diff). Transfer case is 75,00km normal and 45,000km for severe. That sounds about right too. After 12,000 odd miles your not even close to a fluid change. Time to find another dealer me thinks...
PS. The US site has a service schedule link but I can't for the life of me get the Eclipse Cross to show in the drop down menus:
