When I put the car in park, all of the positions are selected like in all gears.

What is your question?

I had a used transmission put in about 18 months ago, the shifter has been sloppy since then. The shop I worked with went out of business and I just never took it somewhere else. Is there an adjustment to fix this and tighten up the sloopiness? They are all selected when I put it in neutral also.
