I know nothing about the inside of the tranny, but I flushed mine last summer, and I plan to do it again this summer. It just seems to me that if there is junk inside of the tranny, it needs to be removed, and it seems to me that a flush will remove more of the 'junk' than a drain and fill.
Just my $.02. I know nothing.
