You should change your transmission fluid between 125000 km to 150000 km with the filter for an automatic . and the same for a standard without the filter . because there is no filter required for a standard transmission .
On any vehicle, the filter and trans fluid should be done at least every 50,000 miles. I actually change ALL my trans fluid every 30,000.
Should be located inside the transmission oil pan
you should. its def worth it. you dont absolutely have to, but you really should.
I recommend you change it every 75,000 miles.
Shifting of the automatic transmission should be smooth. Try changing the transmission oil and filter. If you take it to be done make sure you specify that you want the pan dropped and the filter replaced, as many places suck out the old fluid and do not change the filter.
Honda recommends changing it at 100,000 miles. I personally recommend you change it every 75,000 miles. The 2003 Honda Accord had problems with the transmission so I would recommend this as a preventative measure.
Drain and change fluid, filter, and gasket
