2012 Koleos CVT fluid filter

Yesterday I stupidly drained all the CVT fluid instead of the engin oil from my 2012 Koleos 2.5lt petrol. Dumb move I know (never trust me to service your car). The drained CVT fluid is now tainted (I had debris in it from the oil collection pan) so I will need to refill with new fluid. While I am at it, are there any filters I might as well change in the CVT transmission or is there no filters in it? Do I simply refill with fresh CVT fluid? I emptied out about 10lt of fluid. Yep, expensive...
