I drained mine after I bought it to be sure no metal or other stuff would come out and it was clean. Mine took 1.5 quarts before it started to dribble back out the fill hole. A piece of advice for any drain and fill type situation, take the fill bolt off first and develop your plan of how you will refill it BEFORE you drain it. I used a funnel that has a 2 foot long tube that is about 1/4" diameter and stuck the end of it in the transmission and made sure everything was all set to go before draining, then I lifted the front of the car with a jack and pulled the drain bolt, let it drain until it was down to drips, put the plug back in, lowered the front so the car was level and filled it until it started to dribble a bit out of the fill hole and I screwed the bolt back on with my fingers, raised the car again and tigetened the bolt and gave it a test drive. I'm using Amsoil product code MTF and it does the job well for me, most here seem to prefer sticking to the Honda specific brand.
