I have a problem with removing the gear knob in my Alfa 156 2.0 TS from 2001. I can easily unscrew the gear knob itself but I cannot get the metal piece off. I have tried to unscrew it as well but it did not work. Neither did pulling it towards me.
Attached is a picture of my gear shifter. I have marked the metal piece I want to take off with a red arrow.
