You need to buy or make adaptors to suit the oil bottle and inspection hole in the bottom of the pan.
The transmission is gravity-filled.
The filter is above the pan.
To drain, you remove the inspection plug, then the level tube which is in the same hole.
To re-fill, you reinstall the level tube, fill the transmission, run the engine to get the transmission oil up to temperature, and let the excess oil drain out, before re-fitting the inspection plug.
