Google it. You would do more harm than good if you flush it.
If you want to change the ATF, do a drain and refill twice with filter change each time, about 1k miles apart. You can do more than twice but it'd be pretty much waste of money after that. Since there would be some ATF in the Torque Converter, you can only replace about 75% of the old fluid the 1st time. The second change will bring it to about 90%. Remember the Lifeguard ATF is not cheap. GL.
