You need to read more closely. Being transgender is not in the DSM-V. Yes, Gender Dysphoria is, but part of the diagnosis for Dysphoria is suffering from distress as a result of feeling as though you are the wrong gender. While many Transgender people suffer from feelings of Dysphoria, most do not qualify for the medical diagnosis due to the fact that they are not in distress according to the DSM.

Additionally, it is important to understand the context behind WHY Gender Dysphoria is even in the DSM-V. Thankfully, I don't need to try and draw conclusions on the subject, as the APA literally wrote an explanation themselves.

A few relevant quotes:

"It is important to note that gender nonconformity is not in itself a mental disorder. The critical element of gender dysphoria is the presence of clinically significant distress associated with the condition."

"For a person to be diagnosed with gender dysphoria, there must be a marked difference between the individual’s expressed/experienced gender and the gender others would assign him or her, and it must continue for at least six months"

"Persons experiencing gender dysphoria need a diagnostic term that protects their access to care and won’t be used against them in social, occupational, or legal areas. When it comes to access to care, many of the treatment options for this condition include counseling, cross-sex hormones, gender reassignment surgery, and social and legal transition to the desired gender. To get insurance coverage for the medical treatments, individuals need a diagnosis. The Sexual and Gender Identity Disorders Work Group was concerned that removing the condition as a psychiatric diagnosis—as some had suggested—would jeopardize access to care."
