(hold a rag under the column if you are worried about dripping on the floor mat or carpeting) After you spray it pull the shift lever up toward you and push it back down toward the dash. The knob should move up and down a couple of inches. Do this 4 or 5 times. This will help free up any sticking in the shift lever tube so the detent will do its job. Be sure and spray the bottom of the tube where the shifter arm is also. The reason the shift lever moves up and down is because it should be pulled back towards you to shift it into and out of the park position.
