I cut up a flexible plastic coat hanger to fix mine, I cut some extras too and threw them in my spare parts box I carry in the Jeep in case it happens to someone else on the trail. A plastic coat hanger has enough flex to make the bend without problem. You just need to whittle down the tip diameter a small amount so it fits inside its hole in the shift knob handle. It works very well.
I went to Ace Hardware and bought a dowel rod of sufficient diameter and it must be too long or something because when I press the button on the handle, the handle pops off in my hand. Ugh.
This shit is getting ridiculous.
