Buick Roadmaster with Dynaflow Transmission - per a number of questions, the starbursts are natural
I appreciate your comments on my images, both old and new.
On March 5, 1948, a presentation by Charles A. Chayne from the Buick Division of the General Motors Corporation in Detroit, Michigan, changed the view of a tranmission forever. In front of a group of his industry peers, he gave an overview of a truly remarkable gearbox: one that required no driver involvement. On that day, the inner workings of the Buick Dynaflow torque converter transmission were revealed. Upon its introduction, motorists flocked to the two-speed transmission. In fact, so widely accepted was the Dynaflow by the motoring public that, even as other manufacturers introduced their own automatic transmissions with torque converters (in contrast to the previously employed fluid coupling), many drivers referred to every automatic transmission as a Dynaflow. This was much to the chagrin of the competition, since Buick was being credited in the mind of the consumer as the inventor of shiftless driving.
Buick claimed that the Dynaflow fully automatic transmission offered a heretofore unheard-of degree of driver ease, flexibility and performance. The Flint, Michigan-based company also stated in its advertising that it made the automobile safer to operate, because it allowed the driver to pay more attention to the road rather than being concerned with making manual gear changes.
