Welcome!

I agree with my buddy Bill except for a nit-pick

In stock form, the spec'd differential oil is in the neightborhood of 89W-90. In later 8.8's, the fluid-viscosity he mentioned was indeed used, but AFAIK, the lesser-weight stuff is still in vogue with the fox III guys. That said, ahem, I do run the thicker oil. BUT I probably would not in a colder climate (I live in the desert).

And I still recommend 50/50 water/antifreeze mixes, especially since it's coming up on winter and we don't know that you dont live in Alaska.

Enjoy the new ride!

How many miles does the tranmission have on it? A lot of tranny techs don't recommend changing the transmission fluid if it has not be maintained on a regular basis.
