Different materials expand at different rates. Ideally, the female threads will expand (open) faster than the drain plug.One thing these bitog guys taught me is that heat is a great friend to have. I don't understand how enlarging something makes it loose?????
But some heat and an impact should work.

Project Farm (I know...) did a test on various socket sets. One of the interesting findings was that many brands, including high end, have a chamfer on the end of the socket that prevents actually gripping the nut/bolt. It turned out that the ones that had no chamfer woulde do better loosening a bolt even from a cheap set. So perhaps sacrificing a socket by grinding down the end until the chamfer is gone would be effective.2003 Suburban 1500 transmission drain bolt is very tight.
I don't want to damage it or strip the pan.
Will this come out eventually or damage something if I continue to work it?
Would like to have this available for future drains, otherwise I will just lower the pan.
Wow, PF got something right.Project Farm (I know...) did a test on various socket sets.

In that photo that is such a bad design. Must have be a high paid engineer with a fancy multimillion dollar cad system, that figured that out.
First off the raised area should be on the other side because you would never get all the fluid out of that pan since that hump allows a puddle to form about that same height actually the nut makes it even deeper. The nut should have been welded around the full circumference so it would not break away for any reason. That is the reason they stopped making them with a drain I would surmise. Just more thoughtless engineering in todays automobiles.
Is that the reason for the shallow head and always seems to be overtightened? If so, that's pretty lame.The drain plug was only to help prevent/decrease fluid loss during pan drops under warranty diagnostics/repair.

I have never been able to remove one manually. I never understood the reason why GM made them that way; I was sure it was a mistake.
This is a must! And as Jeff said, make sure you push up to fully seat the socket..... 6 sided socket...
I have the same set up in post # 3 I'm looking for the seal for the small bolt any suggestions ?
