Hi all. I've had my G25 for a few years now and the shifter is starting to play up . Basically, when I'd be driving with the shifter in sequential mode, I'd have a situation where sometimes I'd get a double upshift (e.g.: 4th, 6th) so there is something wrong in the shifter. I opened it up after seeing a few videos and read a little but after taking it all apart and removing the shaft from the casing, I couldn't determine where the micro switches are. I could see a white plastic base at the bottom of the metal shaft so are the micro switches in that? How do I remove them so that I can put in new switches? Also, what micro switch part would you recommend for replacement? Thanks.
