One clue that will usually get you straight on fluid flow direction: Look at the external coolers ... they are always: "in high -- out low" ... this is to keep particulates flowing thru back to the tranny pan.

Of course, particulates still get trapped ... some coolers actually have metal mesh in them trapping particulates, mostly at the "in" end. It's more trouble, but some folks ...when flushing ... will cross-hook the hoses so that the fluid goes backward thru the external coolers. This helps to flush out more of the trapped stuff.
