Shift Valve – Lamborghini Gallardo LP560 LP570 E-Gear
The shift solenoid valves (marked with “PPV”) are responsible for changing the gears of the E-Gear system. There are two of these valves on the actuator. Together with the on/off valve, they operate the shift actuator. If one of the valves is faulty, the car will refuse to go into one or more gears.
