The BMW trans filter kit:

Does not come with any Mechatronic bridge seal etc BUT its a good idea to change it once while your in there. On the other hand a few people have told me not to mess with it unless its leaking and to only do the Trans service with the above kit (but using the steal gasket 24117588753).
