Got a NV4500 4wd small shaft that had a cracked case. Had a welder repair case (the correct way for repairing cast) then reinforced. Reassembled trans and it looks good. The crack was on the drivers side towards the top of the trans. It was about three inches long through the web reinforcment NV casts into the case by the bell housing top mounting bolt. The case was heated to 500* then welded with some type of cast powder method (I'll have to ask the welder)
Side note: The owner of the parts deliverey truck broke the case of the replacement trans in the similar area, I never touched the truck just got the trans after it was removed. The break was not from an accident. Maybe really bad motor mounts?
18969 is the zip.
$1300
