I have had a Syncro tranny welded before but a different section of the
case. It seems like asking the welder would be the best thing. Myself I
would be inclined to try to glue it first. Just drain the tranny
completely, then jack up the DS to tip any remaining oil away from the
crack. Clean, wait, clean, wait, clean, etc until I was sure the oil was
not still seeping from the crack. Then scuff the crack area with
sandpaper. There is some 5 minute JB weld that I have used a few times
and it sets up quick.
