I have two Ts as well, both very different specialties. I might be in the minority here, but not only do I bring up whatever needs to be brought up with either, they also communicate regularly to coordinate my treatment plans. I do have two very different focuses so each T has a specific role, but sometimes something comes up and I do talk to one about the other, and vice versa, knowing full well they will communicate with each other, likely sharing what I've said. I really don't care. Having the two of them has saved my life, the fact that they talk just helps me receive the best support possible.
