Transmission Speed Sensor – Volkswagen Shiftmatic
This sensor provides the speed signal of the transmission input shaft. The speed signal is required by the control unit to control the transmission system, adjusting properly the shaft speeds before engaging and disengaging the different gears.
Valve Body Separator Plate – Volkswagen DSG DQ500 DQ381
The separator plate of the valve body is a high-precision component for the DQ500 and DQ381 dual-clutch transmissions. It functions as a critical control plate and seal within the mechatronic unit, directing hydraulic fluid through the integrated channels – for example, from the solenoid valves to the shift actuator or the clutch. It is recommended to replace this plate when working on the mechatronic unit.
