I hade the trans bolts on my '04 T come loose and ended up breaking one off. I got a good easy out, soaked the broken bolt from the top for like 2 days with penetrating oil, drilled clean through the bolt, carefully put some heat on it and thought this will be a cake walk but to my surprise the SOB didn't even budge. I soaked it another day. Went back out try again and after getting so frustrated I decided to really put some force on and shattered the easy out. Never had this happen. So I am now coming to you knowledgable brothers to enlighten me with tricks to get the rest of the easy out, out, so I can just drill the whole bolt out and retap to a bigger size.
Thanks
