I had this issue on first gen silver2 thumbies that frayed a shift cable. Fixed it by rotating the metal piece between the shifter and mount with the stop on it so it prevented the shifter from pinching the cable like Max showed. That occurred in 2020-ish I think and hasn't happened in the 4 years since I fixed it. I can snap a photo of the "fix" if needed.
To answer the question - it's the thumbie mount, not the shifter that is the culprit. But it is fixable with the parts you've got and you don't need to order new shifter mounts Collin in Oaktown On Sunday, September 28, 2025 at 9:19:27 AM UTC-7 [email protected] wrote: > Recurring (twice) problem, But first a little background.
