A hydro-volumetric transmission of a vehicle has a controlled hydro-pump, a control dispenser of working liquid, a system for control of productivity of the hydro-pump; at that the system for control of productivity of hydro-pump has a feeding pump, this is mechanically connected to working shaft of the engine, a hydro-cylinder, inside it piston with rod are placed, the last one is connected to the mechanical controller of the hydro-pump. The rod part of the hydro-cylinder is hydraulically connected to the pressure mains before the control dispenser. The rodless part of the hydro-cylinder is through control valve hydraulically connected to the discharge main and the feeding pump. The control valve is through electronic control block electrically connected to the engine.
