    Well, its hard to say. Are you sure the noise is coming from the converter? Does it move at all? If the reverse is gone, and the other gears work atleast somewhat, your tranny is gone. My reverse was the first to go too. The clunking could be a broken impeller inside the TC, or possibly a broken oil pump behind the converter. Could be a broken planetary somewhere. Again, hard to say without further diagnosis. I would just replace it or rebuild it with better parts and be done with it.

    I would suggest going with an 87 and up tranny, with a 92-93 (i think) being even better. They made many improvements on the 700r4 over the years, including a thicker 3-4 clutch pack in the later years. My tranny date code says 93.

    Good luck...
