Moving gears is slipping off sometimes when I put it in park

So I am sure you can just replace the shifter handle but just to make sure we understand what is happening, can you get a picture of what is happening? I am not sure if the entire stalk is coming out of just the handle part at the end. If we get a picture, I am sure we can come up with a way to repair it. Here are the instructions for replacing the shifter able in the diagrams below. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
