To change the tanny and diff oil they want 400 bucks. The only reason I'm not doing it my self is because I want the OEM long life tranny oil and I don't want to buy a barrall of that shit. They want a hour labor for the tranny and a hour for the rear diff. I mean come on man two fucken plugs on each and 20min to drain and and fill. I'm not being a cheapo but what the fuck. right now I have M1 ATF in the tranny and M1 gear oil in the diff.
