On the MB's I drain the torque converter and drop the pan BUT the '97 Honda CRV is another matter. Up till about 150k miles I would take it to the Honda dealer and have them do the tranny fluid flush (I do not own a tranny flush machine). Now at 210k miles I just drain it and refill it. On this particular application you are unable to drain the torque converter and there is no filter to change that I know of. Tranny still works fine although it does shift a little harder than it did new.
