Re: CRACKED TH350 Bellhousing!!!
Well it looks like you'll have to pull it back out and have someont weld it up for you. You apparently have something that isn't right......are you positive the torque converter is in all the way?

Re: CRACKED TH350 Bellhousing!!!
Can it be welded without ruining the seals? I think I tried to bolt it on at an angle,

As long as the person welding it knows what they're doing.

Re: CRACKED TH350 Bellhousing!!!
ouch....that metal is a bear to weld, but it shouldn't get your seals too hot as that metal will weld low. the issue i'd be concerned with, as far as your seals go, is that the imput shaft was most likely pushed in when you bolted the bellhousing up (due to improper tc installation), but i wish you luck in that area, and hope you can get someone to fix up that crack.

Re: CRACKED TH350 Bellhousing!!!
 Did the identical thing - reference my thread: 283 rebuild begins.My welder made it look like a piece of cake - but he did take his time prepping the aluminum and apparently knew what the hell he was doing. Took the repaired unit back to my tranny guy to pull the pump and make sure everything was okay. $100 at each shop for my foolishness (they didn't want that much, but I always take care of my vendors). Mac.

Re: CRACKED TH350 Bellhousing!!!
You can probably get a core housing pretty cheap, and just swap all of the internals. Its alot cheaper than welding, its not so hard to do, just repace a few gaskets.

Re: CRACKED TH350 Bellhousing!!!
So I took the trans out today and it looks like it cracked because i tried to bolt it on cock-eyed. Well I didnt bolt it in all the way so nothing appears to be damaged. When I heard it crack I just gave up for that day. Do I need to jack up the motor and jack up the transmission to it so it bolts up correctly and at a proper angle?

Re: CRACKED TH350 Bellhousing!!!
Usually, using a floor jack supporting the tranny you can get the dowels to line up. Push it up tight...then...start the bolts.

Re: CRACKED TH350 Bellhousing!!!
I cracked one of the mounting ears off my T5 in my s10, I had it welded up for $30 and have not had a problem with it since. Been since june it happend! Since the weld wont have to be ground down make sure they leave the weld on the inside and outside, as long as it doesn't hit the TC your good to go!
the welder used 4043 on a Tig, beveled the edges. It was Cast Aluminum also.

Re: CRACKED TH350 Bellhousing!!!
As long as the cracks arent within 2 inches of the pump you'll be fine with welding.
