I have an IS700Z and both transaxles just started having leaks. I have attached an image where it's leaking. It seems like it's where the rod for the brake attaches on the opposite side.
It also seems to leak more after we're done using it and it's just sitting there turned off. This happened the first time on one of them a few months ago, but never saw it again until today.
If it leaks out while the transmission is sitting there then check for a blocked vent which is pressurizing the transmission thus forcing the oil out of places where it should be mostly dry .
