You can use any ATF fluid so long as it has the proper specifications. The Castrol oil I use has the proper specs for ZF transmissions. See the attached spec sheet in post 1. Also, don't put a lot of faith in what dealers state. They misinform customers and sometimes make shoddy repairs. I base my statement from personal experience and by reading horror stories on this forum.
