All those items in theory are the way it's suppose to work however it's Bank of America.
So my understanding is your manager is not notified if you apply for an open position (you can apply to 3 at one time) however if you are selected for an interview your manager will the be made aware. So the last poster is correct you would need to talk with your manager and indicate you want to look for new career opportunities etc.
I have personally found the posting process is slow with very little feedback. The best way to move is to network and find open positions via the good ol boy network is how it really works.
Good luck in your search.
