Push-button transmission, 1956 Packard Clipper automobile

View of the push-button transmission for a 1956 Packard Clipper car. Label on back: "Push-button driving for the 1956 Clipper models. Laid out like component parts of a radio, this is the system which brings the first real concept of push-button motoring to the medium-price car field. The driver has merely to push a button for the driving selection of his choice. The button transmits an electric signal down through the steering column to a 'servo-motor' mounted on the side of the Ultramatic transmission. This motor picks out the right driving position, as a jukebox picks out musical selections, except that with the Clipper electric push-button driving system, the job is done in the smallest fraction of a second. The Clipper push-button automatic transmission system incorporates a 'safety-park' feature and automatically prevents shifting into either 'Park' or 'Reverse' at speeds over five miles per hour. There is no mechanical linkage in the system for the driver to overcome."
