I believe most use 75/90 just like the rear, although that is technically not the exact spec listed by Ford. If you’re doing it yourself, you will need to extract the oil out of the fill plug. Easy job if you have the right tools. I used a brake bleed vacuum pump. There is no drain plug on the pumpkin and removing the cover is difficult.
Most of your questions about fluid spec and capacity can be easily searched on here or on Amsoil’s website.
