Do You Have to Send...

You have to send them yourself. AMCAS does NOT do it for you.

 

This is not correct. When you enter course infomation into AMCAS, it is submitted to the schools. Sometimes a school also asks for a transcript in addition to what AMCAS sends. You only need to send a transcript into a school if they specifically ask for it. Otherwise assume you don't need to send them.

 

Yes, while it's true that AMCAS does send a lot of information contained on a transcript, it does NOT send "official transcripts". The OP was asking (if I read it right) if official transcripts bearing a seal needed to be sent. In that case, he needs to contact his school's registrar's office and send them to the appropriate school.
