How do you completely drain transmission fluid?

If you need to remove the entire transmission fluid pan, unscrew the two upper-most bolts halfway, then unscrew the other bolts all the way. As soon as the last bolt is completely unscrewed, the pan may drop a bit and fluid will begin draining. You may also have to pull it loose using some force.

Is it better to flush or drain transmission fluid?
