Hi, does anyone know how to transfer bo2 map packs from Xbox one to Xbox 360

The map packs are tied to your account. You can (re)download any time. Here are more information how to do that on Xbox 360:

The only way your stats will transfer from Xbox 360 to Xbox One will require the BF4 Premium $50 membership. All stats and map packs will transfer for free. Without Premium you will not be able to transfer stats.

Got banned because my cousin came over and wanted to play his bo2 map packs and didn't bring his xbox so he license
transfered at my house. No sense.

The situation you described makes "no sense". To access his map packs all he had to do was download his profile and then log into the console and download the map packs. No license transfer was required.

@Malacat The season pass was suppose to give us access to the map packs on the Xbox One as well after transferring from the Xbox 360 but none of our content has transferred over. I am unable to download Atlas Gorge or the Map Pack Havoc even though I bought
the season pass.

I have read that there is an issue with some texture or skin packs transferring properly. You could try going back on your Xbox 360, unload the packs from the map, save it again, then export it. Since you also have the packs on the Xbox one, they can be
put back on if the transfer is successful.
