In California you have a few options. When you change your name you can also change your gender but only if you have had a surgery and a letter from the surgeon saying its irreversible or your doctor that is prescribing hormones will sign the court affidavit stating that your changes are irreversible.
If you have a name change already and have not had surgery you can have your Dr prescribing your hormones or your pcp fill out this form for you
http://dmv.ca.gov/forms/dl/dl329.pdf and take it to your local dmv. If your Dr wont put its permanent you can get a provisional license for five years in your new gender while your taking care of everything. The only thing with that is if you get pulled over by a cop it will show your old license and a new one. I just changed everything in California

.
Let me know if you need anything else.
And yes, Dr.Garramone gave me ten copies of a notarized letter saying my surgery was irreversible and a bunch of other wonderful language and said if I needed more just email.
Edit: Apologies, just noticed you said you had your top surgery but the same applies. You need that form to change your liscence or they just wont do it. You can message me if you need anything else, like I said I changed my info with Cali right before I moved to Orlando and it was a bit frustrating.
