I can't believe people still make threads about this. YES HE HAD TSUKUYOMI. YES YOU NEED BOTH "TSUKUYOMI AND AMATERATSU" TO GAIN SUSANOO. IT IS IN THE 3RD DATA BOOK. HERE IS A HUGE HINT THAT SASUKE HAS TSUKUYOMI. Now, a huge hint that tells you that he has Tsukuyomi is when he uses it the panel always focuses on his right eye. Some times he uses it with his left closed which signifies that he is indeed using a MS technique with that eye just like when Itachi uses Amateratsu he sometime closes the opposite eye. Sasuke's techniques are on the opposite eye of Itachi. If that isn't enough proof then just read the mythology Susanoo.
Mythology that links the 3.
In Japanese mythology, Susanoo, the powerful storm of Summer, is the brother of Amaterasu, the goddess of the sun, and of Tsukuyomi, the god of the moon. All three were born from Izanagi, when he washed his face clean of the pollutants of Yami, the underworld. Amaterasu was born when Izanagi washed out his left eye, Tsukuyomi was born from the washing of the right eye, and Susanoo from the washing of the nose.
