Torque Converter Question

No. The problem with converter contamination is that it builds up in the outer perimeter, and it becomes compacted from the centrifugal force. Not to say that after your rebuild, a couple gallons of high detergent scalding hot fluid isn't going to flush out the converter and clog your new filter. I did a th400 once that came in with black fluid; and I didn't change the converter. Now a th400 filter is one of the easiest to clog, but still, it took four fluid and filter changes to make it stop whining; caused by pump cavitation from not being able to suck up fluid thru the clogged filter. Plus the fact that the converter can become unbalanced what with all the buildup. The flushing or reinstalling it and letting it flush itself, can cause further imbalance of the chunks come out unevenly. What went into the converter as dust particles, wash out in chunks.
