Just do this. http://www.thenewx.org/forum/15-how-tos/30213-how-transmission-pmf-poor-mans-flush.htmlI have 6 quarts of Redline D4 sitting on the shelf. I will probably use it once I am out of Nissan S Matic.
I got lazy and have gone the route of sucking it out the fill hole. Getting 4 quarts at a time. I am thinking I will run 10 quarts through it and then start swapping out 4 quarts every other oil change.
