Got them all out some of them i could almost break them loose with my hand thanks again for the help gents.

 

+1 on th T-50 bit. Otherwise, those bolts will strip at the head... as you've seen.

 

why are you trying to take these bolts out? I'm a little lost on that one.

 

He bought a new trans, it didn't come with a bell housing...

I see you got them out, but in my turbine shop when a bolt is seized up in a case, Liquid Wench Penetrating Oil around the bolt head allow to soak in, over night if possible, Heat, Allow to cool (The difference in material will expand and contact at different rates and could break the bond between the two), Heat until hot, Spray Penetrating Oil (carefully this might light the oil on fire if it is hot enough, don't think it's wise to get it that hot on the bell housing though), Strike the head of the bolt with a hammer, this will break the bond between the bolt and the case (hopefully) and should be able to back out, if it doesn't work the first time, repeat. I realize this is nearly the same as what everyone else is saying, but shocking the heated bolt that is surrounded by penetrating oil with a hammer is the best way to break it free.
