if you want to prevent N or R notch where its shaded ,i chose to add height to the N slot rather than cut it .
if you want a stop at third notch the third gear slot slightly and leave a tip at the edge to catch the hook, this could be done to the 2 slot as well for a more positive click but leave the tip shorter and softer (like a bump) so you dont need to depress the button to move it to third
, the plastic rod that runs down the shifter stalk is threaded and spins to adjust depth travel of the pin into the gear selector gate , reinstall the handle and clip and take the time to adjust the jhook while the console is off .
for first gear (tbrake) being the lowest gate slot I just adjusted the hook rod so that i would have to just reach in with my thumb on the shift button to get the rod travel to go into the 1, once its on tbrake you only need to bump shifter forward without having my thumb on the button which if you did use the button and didnt set it tight you could accidently pull it back in to the brake .
