hello on the 206 automatic transmission sump you have a drain plug ,about 22 mm I think and in the centre of your drain plug you have your overflow plug 19 mm,two drain your box take the 22mm off you will have a metal tube attached,when refilling your box just put the 22mm plug back leaving the 19mm off ,then take of your plastic breather pipe to your air filter,put your auto handle into the lowest drive,then look at the top of your gear box,you will see a 8mm square stud .that's your filler,get a plastic tube and push it to the bottom of the box then attach your full and pour in your fluid,when the right amount is in it will start to run out,then put back your 19 mm stud into your sump screwing it into the centre of the 22mm one,then put back your 8mm stud back into the to of the box,then take for a run to warm up and recheck the level by undoing the 19 mm again,a little will come out,then you will have too get the ecu reset
