This spring I want to change the transfer case fluid (from what I understand it will need 2 quarts Mercon fluid), front and rear differentials and the auto transmission fluid. I am not sure what differentials are in my truck, I have a manual but is says there could be a number of different differentials that could be in my truck ranging from a ford 8.8, 9.0 10.25 or Dana 44,60 or 70. Can someone explain where I could find out what differentials are in my truck? The book says I should use Hypoid gear lubricant or gear oil depending on the differential. Do I need an additive???

Also the book explains that there could be five different transmissions in my truck including C4,C5,C6, AOD,E4OD. I would imagine that mine contains the
E4OD transmission but I could be wrong, can someone clarify.

Thanks
