So after hardly over a year of very light use, my G25 shifter has come down with the infamous gear hopping issue. Since it is out of warranty, I looked on ebay for replacement shifters but they're all gone. I have also opened the shifter up but it looks pristine inside with no loose connections or pinched/broken wires. I don't know where to go from here and could use some advice. I really don't have the money to spend on a new wheel setup. I hope the shifter works when i put it back together but I won't hold my breath.

For whoever cares, it ended up being 2 broken wires going into the horizontal positioning pot. Soldered them back in, put some silicone back on, and wire loomed the wiring so it shouldnt happen again. Working perfectly again!
