At the time, six years ago, the primary reason I went to a therapist was for all the baggage I accumulated from being trans. I needed a new/better way to think of myself and the world. Unlearn bad behaviors, such as those that exploded my life, etc.. I knew being trans was at the heart of it all, yet I wasn't going there to start transitioning. Been there, tried it twice years (decades) earlier. Still I needed to find a T-Friendly one out in the boonies.
So... yes, do start out putting being trans on the table. It does not mean you are primarily there to start transition. A Gender Therapist I see now is far better with all the assorted baggage then the generalist I was seeing. BTW - six years later I still don't know about transitioning. But is no longer off the table, more like how and when
