1998 Accord Transmission fluid DRAIN??

I had to do the service on my fathers 1998 accord lx 4cyl, it just hit 60k miles and i changed, plugs, cap and rotor, air filter, LOF, and i was going to drain the transmission to change the fluid. (the dealer told me that it only needs 3 quarts if im only going to drain the pan and not the whole transmission) But i cant find the drain plug for the transmission, any help would be greatly appreciated
Thanks, Andreas
