My own thoughts are like Transgender = crossing (trans pre op ) full-time into the other gender (mindset) in actions and appearance than wut you are assigned at birth (as per your sex). Transsexual = having actually physically like totally crossed (trans post op ) to the other sex (male/female) that you shoulda been at birth. I feel that CD and TV and other acronyms are a totally different category or wutever with their own meanings. It's like the categories of car, bus, truck is to "vehicle". This is, of course just my take on it, but it works for me. You ask a dozen others or wutever and you'll get a dozen answers lol. Main thing is we all do wutever feels right for ourselves.
