I have had my g25 for 3-4 months now, and it is developing shifter issues, e.g when i put the car into first gear (H pattern mode) and drive in first for a little while it drops into neutral, this can be very annoying and now the shifter has started getting problems in sequential mode too, it just chooses to drop gears randomly, does anyone have an idea as what this problem could be and how to fix it, thanks...
