+1 i had the same problem and it was due to a cut wire and another wiring almost falling apart. You can try connecting the wire back together but I just got a new shifter assembly off the forums and swapped it and now its all good. Ebay may have a couple shifter assemblies for a reasonable price if youre looking to replace it
