I have a 2006 K9 and do all my own work, I recently serviced everything for the ride to daytona. when I service trans. could not get a good reading cold, so I added a couple OZ more. not sure what yours takes but 20 oz for k9, now I have slow leak coming from left side where seal is - I have open primary and it is coming back side between trans. and backing plate and my breaker hose is right near there. I am just going to let it leak and find its own level this time. before this I have away just put in 20 oz and no problem. hope this helps maybe it was over serviced like mine.
