PROBLEM

Show/hide table

ACTION REQUIRED

Show/hide table

If, after following the troubleshooting guidelines, it is apparent that there is an electrical issue internally to the lever, then replace the existing 3109354/">310-9354 Transmission Control Group lever with a new one. The new control lever has improved harness retention inside the lever to stop stress on the soldered joints.
