Let me just address this all at once.
Transracial is usually a term used with adoptees who were born in another country/race/ethnicity but raised in another, which can create very complicated identity issues. What people seem to think that transracial means: “I am (insert race here) but oh man, I just feel like I should’ve been born (insert race here)”. 
Stop.
You get people on Tumblr talking about “transitioning from white to black”, editing their photos to look “more Asian”, and comparing being “”“”transracial”“”” to being trans*. Which is SO FUCKING PROBLEMATIC IF YOU CAN’T UNDERSTAND THIS WHAT THE FUCK. It dismisses experiences and all the shit trans* people go through, it appropriates certain parts of a culture, and it perpetuates stereotypes about exotified and romanticized culture!
Here’s a pretty good response to all this.
And if you still have questions about being transethnic or transracial, I highly encourage you to read THIS POST.
