I'd say that both are correct, but not all the time.
The reason for this is that not all transitive phrasal verbs are separable.There are some transitive "take objects" that can't be separated even if the object is a pronoun.
4 example: I'll look after the house while you're out.
I'll look after it while you're out.
But, I'll look it after while you're out. Incorrect
I think the way you differentiate between all kinds of phrasal verbs is much easer than learning their meanings by heart.
