transmission flush?

[dumbstroke8]

i need to flush my sister's transmission (cuz i'm such a nice brother) on my her 1996 altima. can i just hook a hose up to the radiator or one of the lines to the radiator then run the car, or is it much more involved than that?

much more involved then that. You need a machine that can pump new fluid in as the old pumps out. A drain and fill is pretty much what you limited to unless you want to pay a shop to perform the flush.
