Abstract
The invention relates to a hydraulic system for a vehicle transmission, comprising: a hydraulic circuit arranged for generating a pressure, a hydraulic actuator arranged for engaging a park lock system, wherein the hydraulic actuator is hydraulically connected to the hydraulic circuit for actuation of the hydraulic actuator using the pressure, and a back-up system configured to keep the pressure above a predetermined pressure threshold for maintaining an actuation of the hydraulic actuator for a predetermined period of time in case of an operational interruption of a transmission control unit of the vehicle.
