Rockauto says to put ATF in my differential

When I went to purchase differential fluid, it listed ATF. I am not a car expert and I'm here trying to learn.

No where did I say it spec'd ATF. I stated that they only list ATF. I even posted a picture of it. My apologies that we can't all be ASE certified bobistheoil guy experts.
Yeah basically for fluids don't trust any listings unless in the owner's manual or FSM.

I never trust fluid listings even on AutoZone, O'Reilly etc. They'll usually show nothing, everything, or just universal fluids like coolants.
