reverse, neutral and park. There was also a "signal" button which was the horn. A housing containing four large solenoids was mounted at the transmission which acted on the steel transmission shift control rods. The driver was free to select any gear at will, enabling the bypassing of gears, such as jumping from first to third gear without going through second gear. There was a cautionary advisory with the car that one must use care when placing the selector into reverse, only doing so when the car was completely stopped. Pushing a button on the shift control preselected the chosen gear. The electrical circuit was closed only after the driver fully depressed the clutch pedal. This energized the appropriate transmission mounted solenoids necessary for returning the transmission to neutral and then completing engagement of the preselected gear; the driver would then release the clutch pedal to continue onwards. These seemed to have been very advanced automotive systems. The Vulcan Electric Shift Company was located in Philadelphia, Pennsylvania and was eventually bought out by Cutler-Hammer. The model year 1914 was the only year that Norwalk used this system. Only one known Norwalk Motor Car survives today, which is owned by the friends of the Norwalk Foundation, Inc. in Martinsburg. Haynes was evidently the only automaker of note to place the push-buttons in the center of the steering wheel. The Vulcan electric gear shift system probably didn't survive past the early 1920s, since nothing regarding it has been found in the automotive engineering literature past 1921, and a 1919 Haynes print ad has been found with no mention of the electric shifting system. Chrysler Corporation automobiles introduced pushbutton automatic transmission controls for their PowerFlite and Torqueflite transmissions for the 1956 model year. Instead of the traditional placement of a gear selector on the column, Chrysler's system mounted the gear buttons in dashboard pods to the left of the steering wheel, becoming the first U.S. carmaker to offer such a system. This system was mechanical. Packard also introduced a steering-column-mounted electro-mechanical pushbutton transmission control pod in its "Touch Button Ultramatic" in 1956, placed off to the right of the column about . Using technology that it purchased from a Packard supplier, Auto-Lite, this push-button system proved problematic as the electric motor was insufficient to move the car out of Park on a steep hill, and would pop the circuit breaker; electrical contact problems,
