A hydraulic transmission, characterized in that it consists of a variable displacement pump, a variable displacement motor, piping elements that communicate the pump output with the motor input and the motor output with the pump inlet, means of manual control, selectively actuatable in a first mode, to increase the stroke of the pump and decrease the travel of the motor to bring the power to the level of the speed, in a second mode to maintain the pump travel and the travel of the motor of so that the output speed and the torque are maintained and in a third mode to increase the travel of the motor and reduce the travel of the pump in order to reduce the output speed, and a superimposed command, obeying the increase in pressure in said pipe elements above a predetermined value during one of the mentioned modes for overcoming the manual control means, to fi n to govern, the route of the pump and the motor.
