Raise it to the full tilt position, Remove the fill plug and top it off with Dextron II. Then cycle it up and down 10 times checking the fluid level while doing this. Post a pic of your black switch.

Yeah... what Boobie said.... BUT.... put that screw plug back in before you drop/raise the engine, otherwise you'll have fluid shooting all over the place.

Best way to fill is using a 20-30cc syringe (vet/farm supply), and attach a length of thin tubing to the tip. Draw fluid from the bottle and inject.
