Workshop manual says that tranny is keeping some info on oil quality, so it is better be reset with the scanner after oil is replaced. I did not reset it and no major problems on 15K, but I also did not replaced filter (my mechanic told me that it might cause lot of problems if you put any dirt there, so he refused to change it by himself). I'm going to replace filter and oil again, and reset the tranny during next 5K.
