    I got a new th350/NP203 combo for 150 bucks...

    The bellhousing is cracked off from the little aligning nob abovethe starter to the first bolt hole up... about three inches total... Is this fixable... can it be welded back on...
    Or did I just buy a piece of junk...

    My bellhousing cracked also. If you search I asked this question with some good answers. Ended up buying a strong built Th350 and replacing it. Mine started as a small crack and by the time I replaced it the things was cracked from one end to the other, still ran though.

    As long as you're okay with it, get someone that welds aluminum to weld it up for you. I think it'll work fine.

    Welding cast aluminum is very tricky. The material is brittle as you found out and it just soaks up the heat. This can lead to spiderwebbing and more cracking. I've welded cast aluminum and it is a beotch![​IMG]

    I would consult a reputable tranny shop and see what they thought of it. Myself I would be looking for another case.

    Yes, with the right equipment. I personlly wouldn't attempt it, I'd have a pro do it. Aluminum is funny like that.

    I hope you KNOW that tranny's good.

    Call aluminum head repair shops. They are obviously pros and are comfortable welding it. I had a tranny pump welded up, no problems.
