I don't believe that the 98 auto tranny has a filter. These trannys, along with the Accords of these years, have many problems if not well taken care of. Just Google civic accord transmission problem, you'll see what I'm talking about. Best thing to do is to get the Transmission Fluid serviced by Honda and make sure they use Honda ATF-Z1 fluid. Anything else will mess up the seals on the transmission, causing leaks, bad shifts, and ultimately the P0740 OBD code, which means transmission failure. Don't service your Honda transmisison yourself if you don't know what you're doing.
