Gearbox Valve Parts

Gearbox valves control air or hydraulic pressure within automated and semi-automated transmissions, enabling gear engagement and clutch actuation. Valve contamination or internal failure causes missed shifts and transmission faults. Gearbox valve issues are common on Volvo I-Shift, Scania Opticruise, Mercedes-Benz PowerShift, MAN TipMatic and Iveco automated gearboxes.
