I used their severe gear. Once my warranties are up I plan on swapping out all the lube covers I can IE trans pan & rear diff cover for the greater capacity fin cooled & drain plug serviceable covers that many after market companies make for these trucks. I know it's silly cause by swapping these items to ones that can hold more fluid that can be cooled w/ external fins as opposed to stock less efficient parts supplied by the automakers. These auto makers rely on any little changes to void a warranty in a hurry. Don't make much sense but it's reality. Good luck pal.

So did you get 2.3 in just by filling to bottom of the fill hole? like I said I know it takes 2.3 which I got in also but had to fill above fill plug in order to do it. I have lifetime max care warranty so I won't be changing rear covers. Looking for people who have personally changed their rear end fluid in 2012 model trucks. thanks
