Hey there, i'm about to change the oil on my 2011 Sportsman its a 500 H.O. and before i get to doing anything, i am trying to find where to drain and fill the transmission. The dran plug has been found but where is the fill plug at? Do i need to hit this thing with the water hose again? I'm guessing it will be easily found after i ask this question but so far, i can't find it to save my life.
