Flushing a transmission is very near to impossible. A transmission is made up of a whole bunch of channels through which the transmission fluid is pressurized. The pressurization of these channels is controlled by gaskets. The gaskets are never all open at the same time, making it quite hard to flush the transmission.
Also to flush something there must be a point at which the fluid drains; a transmission doesn't have a point for the fluid to drain making it rather hard to do. Attempting to flush a transmission may ruin it.
