Which way does the oil travel thru the Transmission filter 1330 engine?

I have rebuilt thousands of automatic transmissions and most of them have used a filter that looked like that. The only ones we ever cleaned were on some 50/60 models and they were called screens. I also dont recommend cleaning, All you will do is stir up some deeply lodged particles, bringing them to the surface where they will be dislodged upon starting.
