Two questions about automatic column shifter..

[Patrick Sullivan]

1) When trying to put it into park, the shifter just won't go. It goes into every other gear easily, but park is a no-go unless you really put some force into it. If I push on the left side of the part of the column that turns with the shifter, it goes into park just fine. I oiled it up, made no difference. There's no problem at the tranny, all gears are fine down there - so I assume it is a column problem. Is there some kind of adjustment I can make?

2) Does anyone make replacement knobs for these things? Mine broke off, and I miss it..

Thanks..
