Mine did not pop out but simply pulling on it like the instructions say. I had to stick a flat bladed object between the trim ring surround the boot and the textured plastic panel. Hope this helps.
So far I have been able to follow the instructions for the install, but I have gotten stuck at removing the shift boot inside the car. Can someone please tell me how to get the shift boot out so that I can lock the mechanism in place and finish my install?
Thanks for the responses!
