I was planning to change my transmission oil today and got the fill plug off easy, but when it came to the drain plug it was all rusted up and stripped from only a couple of attempts. I already have a new drain plug coming in, so what is my best course of action for getting the old one off? One idea I had was sacrificing the 16mm striple square and JB welding it into the socket. Any other ideas? I would weld, but I don't have the tools for that. Heating it wont really work since there is little to no more teeth to grip on in the socket.
