Hello, I'm Chris. Thanks for visiting Just Answer.
It sounds like you are referring to the brake shift interlock switch that enables you to shift out of park when the key is on the brake pedal is pressed. If this clicking noise occurs each time your press the brakes then yes this switch does need to be replaced, let me know if that's whats happening so I can get you the directions.
To chris aka moose what is the procedure to place the switch and the diffulculty to replace it and is the switch in the console.
See the file below explaining the steps.
