1994 Honda Accord transmission

My wife inherited her mothers 1994 Honda Accord. It's in mint condition with only 40,000 miles. I know the transmission has never been serviced. It doesn't have enough miles on to hurt anything but the fluid is 13 years old. Should it be serviced at this point or left alone? On a Ford Tauras that I had with high milage I was told that it would do more harm than good to service the transmission at that point. The new fluid would do damage to the pumps and seals because the fluid had high milage. Would low milage and many years do the same thing?
