I don't think transracial is a thing. I get how someone can "feel" like another sex/gender, physically..... but I don't know if I can get behind someone feeling like they belong to another race. That sounds like you just enjoy a culture which is associated with a particular race and have an affinity towards all things THAT but again that just enjoying a culture. If the main things that physically divide us as people are our upbringings and experiences, I don't see where race plays any role
