There is a difference between messing with your body and augmenting it. Transhumanists generally believe in augmenting the human body with cybernetic parts, not changing the body's internal chemistry.

But about, as the parent pointed, improvement. Even in a transhumanist society, someone with eyes on its feet or a mechanical arm without any usefulness would be regarded as stupid or mentally ill.
Not all modifications are good &/or transhumanists.
On second thought, what I should have said was "transhumanists focus on improving the human body". Transitioning may improve your mental health (debatably) but it does not improve your physiological capabilities, and in case of MTF transition arguably worsens your body (bone density, muscle mass, fat distribution and so on)
