Theres a drain bung on the bottm, much like sump of engine. There will either be a filler bung, or ya fill it rhough the speedo drive hole (small hole at top once speed is out) that method usually has a dip stick sort of arangement somehow. Filling up via the side bung ya just fill till it comes out the bung, thats the correct level mark.
