I went to change my tranny fluid today and found that my drain plug is rounded out pretty good. Fill plug is fine, and I was happy to find she was at least filled with oil.

Questions:

1) Whats the best way to get this thing out of there? I don't have a welder. Can I JB Weld a hex bolt in there and break it free? Looks like it hasn't moved in decades.

2) I took out that plug on the bottom (the one with the spring and ball bearing) in an attempt to get it to drain. Went back in fine...did I screw anything up by taking it out??

Thanks in advance...

Can you drill out the plug with a slightly smaller drill-bit (17mm), then (carefully) chisel away the remaining threads? How about hitting it with a reverse drill-bit?

I think drilling the whole thing out is asking for metal flakes in your tranny. A reverse drill-bit is a good idea - I bought a large screw extractor as my backup plan - but I did not have to go there. The bolt trick worked just fine.
