1)Where cooling hose is located?
2)How can I suck the ATF out of it? With some suction pump or when I turn on the car, it will pump out it for me.

The AT cooling hoses are the two small (~1/2" in diameter) hoses that both go into the bottom of the radiator (as opposed to the pair of 2 1/2" or so diameter ones for the coolant.

You can loosen the pipe clamps that connect the rubber hoses to the metal pipes and simply drain both sides. No suction is required, and you definitely should not run the transmission to pump it out.
