here's a pic of what your filler bolt should look like. it's on the passenger side of the car. jack up the car, unbolt this, and see if gear oil runs out. if, none comes out add, till it does. you may also want to just drain the tranny, just to see what comes out. as you can see, Honda reccomends replacing both drain and filler bolt washers and using their gear oil, as it contains addatives for smother shifts. the service manual i used was for 96-2000 civics, but i can't imagine your tranny being too different.
