Which transformation are we talking about?
if it's the henge-no-jutsu (Transformation Jutsu) in which Naruto uses in order to transform into a naked woman in order to stun his foes, this is done in episode 1.
If we are talking about the Kyubi transformation, it's on episode 15-16, when Naruto thinks Sasuke's dead.
I think it's episode 107 or around it.
First time they are seen thogheter is in episode 32
