Looking at the pic.... I would replace the ATF hoses, clean area up and see if there is any other leaks. It is important to know what it is that is leaking. However if these lines are oem, they are the most likely to be leaking in the area.
If it is antifreese.... remove the lower Rad hose (have pan(s) under) and inspect it. If it is oem (original) then it would also be likely to leak. Our vx had all original hoses on it when we got it. Most have been replaced now, originals would be 13-15 years old.
