My transmission will not engage on 1999 Buick Century

I changed the fluid, filter, and oil. Checked the filter to see if fell, it didn't, but it still wont engage. there is one weird thing. I no longer have to press the brake pedal to move the shifter. Is there a neutral safety switch attached to this?
