Tranny cooler, replace or flush?
I had my old torque converter go out on my 1990 super duty with a 7.3/e4od and was wondering if I should either flush or replace the radiator since the tranny lines hook into it?

A good thorough flush would be recommended IMHO. Replacing it would entail replacing the entire radiator.
Flush the existing cooler as well as the lines. Then install one of these in the return line:

There ya' go from the man himself. Safest bet: replace the radiator and external cooler.
I'm a cheap bast**d so if I know I had a good radiator and cooler I would try to keep it knowing there is chance debris from a failed converter/trans, could remain even after a good flush. Hence the reason for the inline filter on the return line.
Do you feel lucky punk?
