Doing a flush uses external equipment to pressurize and move the fluid through the trans, this can blow seals, dislodge crap, force particulates where it doesn't belong, but just as bad there are flushing systems like BG that use a solvent to "clean" the system before pumping new fluid in, this solvent leaves a residue that's not compatible with our trans and it'll kill it.
That is the primary reasoning behind the Nissan notice to dealers regarding flushing the trans.
The proper way to replace the ATF is by doing a fluid transfer. This allows the transmission itself to pump the fluid and you're not introducing any contaminants or other fluids that are potentially harmful. Old fluid goes out one trans cooler line while new fluid is sucked in the other line, let it run until you get nice, clean red fluid coming out and you're done.
