I am going to be switching my truck fluids. I will be running Amsoil products in my truck except oil I run Schaeffer oil. What I want to know is what to run in the G-56 and Transfer case? I will be running SevereGear in the front and rear diffs. I have also want to know the fluid capites of the diffs, G-56, transfercase. If anyone has a link to that stuff as I have search for a while and have found a bunch of different if so help me get it straight.
