[crash]

I fix cracked Muncie cases all the time... The easiest why for me is when I have an empty case that I can bolt into my surface plate with cut-outs so I can weld completely around the ear with out un-bolting it from the fixture... If you don't want to dis-assemble the trans you should do as Charlie said and bolt the trans to an old cast iron bell housing, because it will warp if you don't... (if you use an aluminum bell you could weld the case to the bell housing)... Crash
