A = Applied H = Holding ON = The solenoid is energized. OFF = The solenoid is de-energized. *Shift Solenoid state is a function of vehicle speed and may change if the vehicle speed increases sufficiently in Park, Reverse or Neutral. However, this does not affect the operation of the transmission. **Manual Second-First gear is electronically prevented under normal operating conditions. ***Manual First-Second gear is only available above approximately 48-56 km/h (30-35 mph).
