I have a 2015 Ford Fusion and the the shifter travels but it ONLY stays I park.

What is your question?

The indicator light while in "Park," is on the "P". But when I move the shifter the indicator goes blank. It feels like there is nothing restricting the gear shifter so it travels through all of the positions but NO engagement from the Transmision. A buddy mentioned the shifter cable might be broken. How would I determine that? What else could it be???

How long has your 2015 Ford Fusion had this problem?

Just now occurred no early indicators
