Remember, the Dynaflow was developed by Buick for use in upscale cars at a time, after WWII, when few if any of their buyers cared about fuel economy. What they did care about was quietness (Buick developed hydraulic valve lifters), smoothness (non shifting Dynaflow), ride quality (coil spring rear suspension), etc.
FWIW, the Dynaflow did have a low range but it was selectable only by manually shifting the selector into L. The Dynaflow did not shift between low range and high range. Rather the variable pitch torque converter continually adjusted as road speed increased. The Dynaflow was, in effect, a CVT, albeit a rather inefficient version.
The Dynaflow was produced for over 15 years making it, along with the Powerglide, TH 400 and Torqueflite, one of the most successful automatic automotive transmissions.
