This component is the vital Gasket used to seal the Valve Housing (Solenoid Block) of the high/low range change mechanism to the main body of the Scania gearbox (GRS/GRSO transmissions). Known as the "High low control housing gasket," it is a critical sealing component that prevents oil leaks from the transmission and ensures the integrity of the pneumatic control system. Replacing this gasket (OE 2033890 / 2755103 / 2421224) is necessary during any repair or maintenance of the range change valve housing on popular Scania P and G series trucks, including models like the G400 and P410.
