Up/Downshift Issues - I may have found the cause.

[Frostbyte]

To all of us who have suffered the shifting issues on our RT's, F3's, and whatever, after spending nearly $900 to get the left grip assembly replaced, I asked for the old part and then proceeded to tear it down in my electronics lab once I got home. What I found astounded me. It turned out that the issue was a bit of moulding flash on the turn signal lever that over time penetrated then arced out the downshift foil cable so that it would only work intermittently under just the right conditions. It looks to me to be either a design fault or a QC failure wherein the casting flash doesn't get removed.

I have a 2019 RT Ltd, I'm now unable to shift into reverse, or manually shift down with the lever. Was that your issue?

If so, did you replace the whole lever, or have a dealer do it?
