not only can you submit now, you SHOULD submit now. they'll be processed a lot faster earlier in the process. if you wait until oct/nov when everyone else is sending in their LORs and transcripts and such, it'll take a lot longer, and the delay will cause your applications to be considered incomplete if there's no transcript on file yet.
while you're at it, have your LORs sent to LSAC ASAP too.
