303.11.0022 Gearbox Valve for Volvo Trucks

What does a gearbox valve do?

This transmission valve plays a critical role in the shifting and control mechanisms of heavy-duty gearboxes. By regulating the flow of operating media, it ensures smooth gear transitions and maintains the structural integrity of the transmission system under high-pressure conditions. It is manufactured with high-strength components to withstand the demanding environments of heavy commercial vehicle operation.

Compatible vehicles and engines

This component is compatible with various Volvo models, including the FH series (FH12, FH16), FM series (FM10, FM12), FL series (FL10, FL12), and NH12, as well as the VHD, VNL, B10B, B10M, and B12 series. It is also fitted to Renault Trucks Magnum models featuring DXi12 engines. This ensures broad application across diverse heavy-duty fleets.

Installation and maintenance

For proper installation, technicians should verify that the port sizes match the M10 x 1.0 specifications required by the gearbox housing. Regular inspection of connection points is recommended to prevent leaks or pressure drops within the transmission circuit. Consult your authorized distributor for precise fitment guidance.

Troubleshooting and selection

When replacing this valve, ensure the transmission fluid or air supply is clean to prevent premature wear of the internal seals and components.
