Snapped off an ATF pan bolt

[bairjo]

Well i need some thoughts on this one. I did a drain and fill to douche the ATF system a few months ago. I planned on doing a followup drain and replace the filter today. However that did not go well. I snapped off one of the pan bolts while removing it. WTF!...torque specs for these is only 5.6 ft.lbs. That was the only one that I had any problems with. I drilled it and tried and easy out and snapped it off as well. I got it back out though. I tried and cussed at this thing and finally gave up.

What I ended up doing was putting a smear of permatex red rtv high temp gasket maker on the flat metal surfaces around bolt hole extending to the other two bolt holes on each side of it to take up any gap in the absence of that one bolt. I know putting gasket maker on ATF pans is a no-no but i had no choice. I did that along the OEM cork gasket.

So, has anyone else heard of doing something like this or am I screwed and will have leak when i fill it up and run it tomorrow?
Also, the permatex states that it needs to cure 24 hours. Is that really needed? I don't believe there is any pressure to speak on that seal is there?
