I don't think shifting manually in the auto is actually any more detrimental than leaving it in D4 because it is the exact same feeling of a downshift whether you put the pedal down or manually shift with the gear shifter. I can't know for certain but my auto tranny has lasted... a long frickin time, and I will automatically downshift during passionate driving over waiting the slightly longer delay of when you just put the pedal down. As well I will go into D3 to help slow me down when going under 80km. any higher speed it still downshifts but feels too rough for my liking. And even into gear 2 at under 40km. So far nothing bad has ever happened. I don't know off the top of my head how far my tranny has gone. But it's over 200,000km.
