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.

2019 RT Limited.

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?

I had the dealer replace it with a new assembly and had them give me the old one so I could completely tear it down at home and diagnose the issue. I'm a retired,100% disabled electronics tech and Aircraft Electrician, and the contortions needed are beyond my capabilities now. Someone with greater dexterity and flexibility along with a knowledge of electronics and correct specialty tools would be able to do it as you must remove the connector pins from one harness, and after pulling the disconnected harness out, lace the new one through the "Steering Column" before reinstalling the pins in the correct positions. If you're not familiar with this kind of intricate and precision work, I would highly suggest having the dealer do it.
