People who transferred Fidelity Mutual Funds to a Merril IRA - any sneaky fees?

So if I transfer $100k worth of, say, FXAIX from my Fidelity IRA to a new Merril IRA, I understand I can't purchase any more of these. That's fine. But with regards to what I already have...

• Will automatic dividend reinvestment work?
• Will I be charged any sneaky fees on the dividend reinvestment?
• Will I be charged any sneaky fees just for holding the Fidelity fund?
• Will the expense ratio be higher than Fidelity's 0.015%, since it's not in Fidelity's brokerage?
