How frequently does the automatic transmission fluid need to be changed?

Need little bit more detail here.

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.

Hi Scott,

I have got 7 quarts of ATF WS from toyota this weekend. However when I went below the car to open the ATF plug, I could not figure out which kind of tool I should use to open it. Looks like it requires big hex key (bigger than 5/14"). I tried to look for that kind of hex key in local wall mart and home depot but couldn't find one. I would appreciate if you let me know which kind of hex key you used and from where can i get it.

As I mentioned in post #9 above, it requires a 10mm Allen. You can purchase one with a 3/8 socket from an auto parts store.
