you don't flush it , you drop the pan andreplace what oil comes out. replace the filter as well. flushing requires reomoivng a line or piercing it to get the old ioil out while engine runs. dopping the pan will do just as well.

i would recommed a trans flush you could have only 5 quarts out of the pan and if you flush it out than you get 12 quarts out of the whole transmission.
