Don't feel too badly. I changed the rear cover on my Explorer and when I took it to a local service center to have it topped up, the "mechanic" insisted that he had to remove the cover to fill it with oil. He was not aware that there was a filler plug. Now remember, this person regularly changes oil and supposedly checks the fluid level in the differential as a part of that service.
