This component is the main Valve Housing or Solenoid Block for the high/low range selection mechanism in Scania gearboxes (such as the GRS905 and GRSO905). It is the critical body that directs pressurized air via solenoid valves to the range change cylinder, enabling the selection of high or low gears. Replacing this unit (OE 2447371 / 2276250) is often required when the internal air passages are damaged or when the solenoid valves are replaced, ensuring the smooth, precise, and reliable pneumatic shifting in modern Scania trucks, including the New Generation G410-S7 and P360-S7.

📌 OE Reference Number: 2447371, 2276250

📌 Suitable Vehicle Model: Scania New Generation Series (L, P, G, R, S-Series) and later 4-Series trucks that use the specified gearbox type (e.g., G410-S7, P360-S7, and other models with Scania GRS/GRSO transmissions).

📌 Fitting Position: Gearbox (Transmission), Hi/Low Range Shifting Mechanism (Main Body)

📌 Category: Gearbox Components / Transmission Valve Housing

✅ Key Features:

• Main Actuator Body: Serves as the base housing for the range change solenoid valves and cylinder.
• Air System Integration: Essential for controlling and directing the air supply for high/low gear splitting.
• New Generation Compatibility: Suitable for the GRS/GRSO gearboxes found in the Scania 7-Series platform.
• OE Equivalent Quality: Manufactured for structural integrity and pressure resistance required for gearbox operation.
