First, lets discuss what most often represents the term "transsexual"…
What's a Transsexual?
A transsexual is a transgender person - starting from either a male or female platform - that’s determined through therapy and/or their own reflection they were clearly born in the wrong body. They usually have plans to change their gender via “transition” - or have already done so.
Translation?
If you are diagnosed "transsexual" - your transgender desire is of utmost importance to your happiness and well-being and you're intently dreaming of completely changing your gender. This desire and frustration usually starts at a very early age and is something we're born with from the start.
Additional There's a number of TS (transsexual "types" you might hear about - based around where we are in the process of changing our gender)
The two most common, include:
Pre-Op Transsexual
A “pre op transsexual” is a transsexual whose usually already living full time in their new gender but who hasn’t yet had the final / bottom surgery = also known as GRS / SRS. 
Post-Op Transsexual
A Post-Op Transsexual is a transsexual whose already completed “bottom surgery” - GRS. 99.99% of the time she’s been living full-time as a woman for an extended period. Generally-speaking, post-op transsexual women are amongst the most well balanced & evolved transgender women - since they’re now past much of drama associated with being transgender. However, that’s not always the case.
What is a DRAG Queen?
By classic definition, a prototypical DRAG Queen isn’t really a member of the transgender community. They’re more closely with the gay community - versus trans-world. Most DRAG Queen are gay guys that are simply too fabulous to remain a man “all the time”. Thus, some create female characters, costumes and persona’s for DRAG stage performances.
However…since many transsexuals also work as DRAG performers: it’s not so cut & dry.
DRAG Queens used to cause havoc for transgenders in the public domain. Why w’as that? Lots of people’s first direct encounter with trans expression was at a DRAG show. When some performers made playful and crude comments regarding being their sexuality - this caused confusion later when people always assumed trans-expression meant you’re gay. Nowadays, people are much more aware of the differences.
Also, there’s a big difference between doing DRAG...and being a DRAG Queen. DRAG and DRAG-themed nightclubs are at the essence of transgender evolution. It was once the only place for transgender women to find total acceptance & it remains a haven and source of income for some trans-gals to this day. I am now clearly a transsexual woman - but I still do DRAG as a part of my entertainment platform,
The acid test for a DRAG Queen vs. a transgender is what we want to wear and present during intimacy. A DRAG Queen?
They’ll want to lose the get up and be a “guy” in a loving union. A trans-girl? She’ll want to remain feminine in appearance during love-making.
The easiest means of determining the difference? Simply ask. DRAG Queens and T-Girls have no confusion regarding who they are - and who they are not. 
DRAG King
A DRAG King as a woman who creates and presents a male character for stage amusement - often through costume, make up and choreography while lip-syncing a male voice to a song.
Some DRAG Kings are transitioning FTM transsexuals. Others, are heavy duty lesbian dyees with a strong masculine flair. There also a number of gender variant women who identify as Gender Queer who perform as DRAG Kings.
At present, DRAG King show are not as publicly popular as DRAG Queens acts - but interest continues to expand each year.
Thus, in summation:
A Transsexual ia a transgender person whose compelled to change genders on a full-time basis. A DRAG Queen is a female impersonator - a number of transsexual's still work in the DRAG industry as means of earning a living although that's becoming less common as barriers to employment for TS women become less overwhelming.
