This is a gearbox overdrive supply valve located on the clutch pedal assembly, controlling the engagement of the overdrive gear. It is engineered to meet Volvo's precise specifications for smooth and reliable gear changes. A malfunctioning valve can result in the inability to engage overdrive, harsh shifting, or unexpected gear disengagement, impacting driving performance and fuel efficiency.

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a faulty overdrive supply valve may be a failure to engage the overdrive gear, or intermittent engagement. If the problem persists, the transmission may refuse to shift into overdrive altogether, leading to higher engine RPMs and increased fuel consumption. In severe cases, it could lead to drivability issues or damage to the transmission if operated outside its intended gear range.
Before removing the old valve, ensure the relevant system (air or hydraulic) is properly depressurized to prevent fluid loss or component damage. When installing the new valve, ensure all connections are clean and securely tightened to prevent leaks.
Inspect the clutch pedal mechanism and associated linkages for wear or damage when replacing the overdrive supply valve.
