I want to try the process this guy outlines in his video for flushing out gunked up shifter cables. What his video doesn't show is the process he uses to actually remove the cables from the car. I can't seem to find a good tutorial video on this process either. Does anyone have advise or a link to a tutorial that covers removing the shift cables in a 2008 manual mazda 3?
