i have a fiarbanks trans 727 i put a high stall converter on it and wen i was driving it i had a loud raddle sound and was leaking from the bell housing i guessed it was the seal but what would cause the loud raddling sound ??? thanks nate

 

did you make 100 percent sure that the convertor was ''seated'' all the way in. If not the bolts may hit . Thats all I can think of other than loose bolts somewhere.
