I just changed mine at 45k miles(08) and it was black!!!!! i know that oil still works efficiantly even though its black but im glad i did it. of course more of a piece of mind.
knocked out both diff and trans fluid in 30 min. and it was my first time. thanks to the guides on this forum.
Brakes are next......
