The Prius doesn't have a tradition automatic transmission with a torque converter and multiple gear ratios. The gas engine is connected to the wheels at a fixed ratio along with two motor/generators in a planetary gear system. Reverse is achieved by running the electric motor in reverse. There is no reverse gear. Shifting the neutral on the prius just means disconnecting the MGs and turning off the ICE.
