There's no way to deliver an "If you don't... I am going to leave" message that isn't an ultimatum. If you are serious, it is indeed an ultimatum. You already asked for a transfer to a different team, and were told that it was in the works, but not imminent. If you can't wait, then you are right to seek another job. If you really think they don't understand the depth of your concern, and believe that your boss might hasten your transfer if he knew, then you need to be clearer in your communication. You could up the ante by saying something like "I understand this transfer will happen eventually. But this is really important to me, and I don't think I can wait that long." This is still a subtle ultimatum. Only you can decide if your boss will be amenable to further discussion, if you can wait until the promised transfer happens, or if this is a lost cause. For me, I wouldn't threaten to quit until I already had an offer in hand. Your mileage may vary.
