Hi! there is a golden rule never drain until you have opened the fill plug!!!! Otherwise you cannot get the fluid back in! Having said this there is a thread on how to fill, it needs a pump and you have to follow a set procedure it is not just a matter of poring it back in !!!! The fill plug is just up from the exhaust pipe on the drivers side you cannot miss it, it can be a pig to release and even tighten up later!!!! If you get a copy of the TIS it is easy to find!!!!!
I trust we are talking auto box here??? If it is the manual transmission then it is fairly straight forward in terms of filling....
Always said I would go back to a 6 series
