Automatic gear change for cars, essentially characterized by coupling on the drive shaft a movable pinion that automatically performs the change of speed as it is coupled with the corresponding fixed pinion of each gear, arranged for the purpose in the change comprising a shaft with screw endless provided with a longitudinal and rotary movement that receives the driving force through a coupling that can be connected to the electric motor of forward or reverse gear, through the corresponding switch, said automatic connection being made by a needle arranged on the Odometer, which performs the corresponding closing of the electrical circuit of one or another electric motor, through the contacts provided for that purpose, finally comprising a safety-based electromagnet to prevent the passage of the first gear to reverse gear, without previously passing through the intermediate dead center and both directions of travel.
