Code P0708 2014 Chevrolet Silverado Description

The P0708 code for a 2014 Chevrolet Silverado indicates a Transmission Range Switch Circuit High Voltage. This means that there is a problem with the transmission range switch, also known as the neutral safety switch, which is responsible for ensuring that the vehicle can only be started in Park or Neutral. The transmission range switch communicates with the vehicle's computer to determine the gear position and allows the engine to start only when the transmission is in Park or Neutral. When the voltage in the circuit is higher than normal, it can lead to issues with starting the vehicle, shifting gears, and overall transmission performance.
