Transmission issues Not related to a quickshifter mine did not come with one. It pops out of gear at low rpms or deceleration which can lead to an accident. In cornering and braking to rapid deceleration for emergency.it just stopped shifting properly one day. I had some voltage problems on the 5v wire all symptoms are fixed except the transmission. Thinking maybe the GPS gear position sensor. Nope pedal is sloppy and needing manual pressure to stay engaged.
