Boys, don't fight... you're BOTH pretty.
There is a rear differential IF you have the AWD version... if you have the FWD version, then no.
My dealer used 3 qts of ATFWS WORLD STANDARD AUTOM at a $7.78 a bottle and charged me $74 in labor for a total of $104
Considering the time it would take me to track down the right oil, research the quantity, set up the work area, do the task, clean up (including a shower), and dispose of the used oil... I would be hard pressed to get all that done in less than the 1.6 hrs needed for me to just break even economically, let alone save any money at it.
This kind of math works out for the air filters because those are very easy and quick.... but for oil and getting under the car... That is the kind of thing you do for the love of it. Like a hobby. I don't love it, never did, so I pay someone else to do it. That works for me, YMMV.
