I have the same car just 99 it was doing the same but mine has 200k miles and i flushed it ..so if you dont know when the last time your transmision fluid was changed check it because there could be particles messing with the shifting in there... take it to a transmission shop...also they sell stuff in a bottle thats supossed to stop rough shifting not sure it works? Acura/honda have been known for transmission problems so check it as soon as you can.
