is the strainer/ filter supposed to be replaced, i saw a video where a guy changed the fluid on a porsche boxter s, the whole process for changing the fluid was very similar to what you do with a 1krfe automatic vitz, but on my friend's vitz, the filter was not changed.
btw the magnets were furry on the vitz
i was amazed at the similarity, both required the fluid to be filled until it starts dripping out, both cars had similar magnets in the sumps and the filters were also similar looking
