My point was that by not replacing either the converter or the ring gear he could get stranded someplace or like you say, bust up the bell housing. Too many times in the past I had customers complain about the cost of replacing the ring gear or converter and continued "getting by for now" because they were either too cheap to fix the problem, or got some bad advice from someone. In the end it often cost them more than what they would have paid either for a replacement converter or getting the ring gear changed.
