OK so UPDATE: talked to my dealerships service dept, and according to their shop manuals: "if the shift knob on the 2011+ 5 speed is damaged, the entire shifter assembly must be replaced, as the shift knob is not designed to be removed."
Good to know, but it seems kinda foolish to me that they would design it like this.
On the Patriot site I've read of people just taking a saw to the thing and cutting it off. You're committed to replacing the knob then, but that is the ultimate goal anyway. I agree, the feel of the stock knob is terrible.
I'm not familiar with the new design of the Compass shift knob and linkage, but in the older version the shift knob simply was pressed onto the shaft. By pulling upward it would slide off. It was not threaded!
If the new version is not removable cut it off. I cut my shaft down some anyways to shorten the throw.
Must new shifter knobs are made for a univesal fit. Mine was a MOMO shift knob. It has a base collar that has a rubber bushing to provide and expanable but snug fit. It slides over the shaft first and then the knob is set on the shaft it has 3 set screws that tightly hold the knob on the shaft. The shift knob tapers at the base where it has a threaded base. The base collar slides back up the shaft and threads onto the shift knob. This collar/bezel ,whatever you want to call it, hides the set screws and provides a flawless finish. As far as I know most shift knobs are made this way.
Cutting the shifter shaft may prove tricky. It is made of hardened steel made not bend or break. It is really hard to cut with any saw. I used a canvas blanket to protect the interior and used a grinder to cut it off.
