Other advice is excellent -- never try ANYTHING but a six point, high quality socket on it. Never anything 12-pointed. Some PB Blaster helps loosen it up (soak for a day or two). Smack the plug with a light hammer a few times to jar it a little.

I have used an impact wrench out of frustration which worked perfectly, but DON'T do that unless you are sure. But it sure worked. Again, good, six point socket... The quick motion is really what freed it up.

Also, do the fill plug BEFORE you do the drain plug. Just in case it breaks or something. Obviously this is common sense that one would want the trans full of fluid if the head tore off the fill plug or something.

Never used sunshine on an M47 that I can remember. The fill plugs did always come out.

Also apply anti-sieze liberally to the threads on reassembly. It makes this a discussion of the past.
