An electromechanical bypass mechanism is provided for use in a hydrostatic transmission, to enable the user to open or close a bypass to the hydraulic circuit of the transmission through use of an switch mechanism attached to the bypass mechanism in the circuit. The invention also comprises an improved neutral feature for hydrostatic transmissions, with a switch connected to the control mechanism for the unit, whereby the switch is activated to place the unit in bypass when said mechanism is placed in the neutral location. A means is provided for opening and closing a shunt or bypass between the high pressure side and the low pressure side of the hydrostatic system which is triggered by an electrical signal.
