Gear Lever Push-Pull Switch (Shift Anticipate)
General electrical fault on the gear-lever push-pull switch — a low-force capacitive or microswitch sensor in the lever knob that detects the operator gripping the lever before it actually moves. Used for shift-anticipation, where the TCM can pre-charge a friction element so the upcoming shift feels seamless.
