Normal, when you depress the brake pedal and actuate the brake switch, the BCM sends a signal to the shifter lockout solenoid in order to release the shifter from park position. The noise you hear is the solenoid moving the lock mechanism.
Solenoid is the yellow piece with the 2 black wires coming out of it.
It moves this lock mechanism....
