Transgender is the state of one's "gender identity" (self-identification as male, female, both or neither) not matching one's "assigned gender" (identification by others as male or female based on physical/genetic sex).
(Love the word assigned must have been on the work order!)

They seem to be the same, do they not?
No, they don't. Transgender says that your gender doesn't match your sex. Transsexual says that your gender is the opposite of your sex. They are only the same if you believe that everyone's gender is either male or female, which is not the case. Using those definitions all transsexuals are transgendered but not all transgendered people are transsexuals.
