you don't really need a machine to do that. all you have to do is cycle through the gears while draining and pouring atf inside simultaneously. sooner or later you'll flush everything out. it will take a lot of atf tho...

diesoline, yes it can be done. sometimes tho the atf filter cannot be reached without removing the tranny. the cost of pulling down the tranny is what often makes customers think twice about this procedure.

chieffy, i was talking to the owner of autoplus and they returned the machine that sucked oil through the dipstick after 1 use. it hardly got anything daw and was really inefficient. much much better daw to stick with removing the drain plug. hehe!
