the bell housing/torque converter hold a significant amount of fluid, this can not be drained by pulling the pan.

Flushing is done with pressure by a machine at a mechanic's shop. Tires Plus here does it for $100, and they'll change your filter...but they are grease monkeys and I really don't trust them.

Now, if your local mechanic has the time, buy him the parts and even the rtv and a new gasket, and filter, and Nissan tranny fluid to do it...tell him you were gonna do it yourself but you weren't sure on how to flush the thing and you didn't want to have your wife kick your butt when she saw all the tranny fluid in the driveway...and you will, tranny pans don't usually have drain plugs, you have to pull it off full of fluid.

this job best left to pro's...or at least guys in coveralls who've got plenty of speedy dry laying around.
