I take my old used oil to Wal-mart, Autozone etc. to dump it.

What do I do with other old used fluids like transmission fluid when I change it?

 

Just make sure to tell them that it is tranny fluid that you have. They will also take your old antifreeze.

 

I give them my oil and transmission fluid they're saying it all goes to the same dump. No one will touch antifreeze though I wonder why. I just leave it next to the trashcan at the local gas station and drive off LOL. Hopefully they're smart enough not to throw it in the trash.
