You need a knob with a button to shift out of Park.
I went with a Momo shift knob.... same as the one in this thread:
DIY: AT Shift knob removal/replacement
You can find it on Amazon.. but caution... some of the reviews indicate that the product is not genuine Momo.
I ended up buying it from here:

Install was easy.
Good luck
