I have a 5 speed transmission I am swapping into a 73 240 the problem is I cant get the fill plug out. I soaked it with penetrating oil tapped it with a hammer heated the case up with a torch wont budge. Now I have managed to chew the square fitting on the plug.

the plug wouldnt be reverse threaded, would it?

Just to let you know someone is reading.

Sorry, can't help you with the five-speed. Both my four speeds are normally threaded.

Machine shop time???

They are all right hand threads. Use the torch. Aim it at the plug inself about 4 inches away from it. This may take a fifteen minutes because the aluminum will suck the heat away. It will eventually separate the threads because the aluminum expands a lot more then the steel. Try to loosen it while it's still hot.
If you heat just the case it can expand toward the plug making it even tighter.

Ok I will give that a try, I was going to cart it off to the machine shop tomorrow.

I had this happen once to me... AFTER I had already re-installed the transmission from a clutch job and went to refill. Dropped the trans again, uber-welded a 17mm nut on the end, and backed it out with a breaker bar and 4ft fence post pole.

That sounds like a good idea! Not sure why I did not think of that. I took it to a machine shop this morning and they were going to "see what they could do" but they said they were busy and couldn't promise anything. I would have thought I would have gotten a better response especially since they have gotten about $2000 out of me over the past year...
Thanks for the suggestion!

Yeah! Success! I welded a big nut onto the end of the plug and put a 6 pt socket on and got out the jumbo breaker bar, bam! Done!

thanks for the help.
