I think it'd be real tricky, Gary.... The skin of the torque convertor isn't real thick so you'd need someone good with a MIG. Personally, it's a job I wouldn't touch without the customer knowing we could be replacing the convertor even after our efforts. Make sure the convertor is full of oil to help carry the heat away and your welder will probably need to work with real short "stitches" unless he's real brave and sure he wont have a burn through.
