The first automatic transmission to work with a torque converter (rather than a fluid coupling) was the Buick Dynaflow, which was launched to the 1948 product yr. In usual driving, the Dynaflow utilized only the top rated equipment, relying on the torque multiplication from the torque convertor at decrease speeds. The Dynaflow was accompanied by the Packard Ultramatic in mid-1949 and also the Chevrolet Powerglide with the 1950 product yr. Each of those transmissions experienced only two forward speeds, depending on the converter for additional torque multiplication.
