POWERFuTE VS. DUAL-RANGE HYDRA-MATIC (, OLDS, , LINCOLN)

Dual-Range Hydra-Matic has no torque converter­ With PowerFlite, the torque converter acts as a built-in merely a fluid . Therefore it must depend upon "fluid gear," and makes the three jerky mechanical four mechanical gear combinations, which provide only shifts of Hydra-Matic obsolete. The torque converter of four fixed gear ratios. Furthermore, the driver must PowerFlite, plus the planetary gears, automatically pro­ continually shift manually between two ranges if he vides the exact gear ratio for every driving condition, is to get adequate performance and maximum economy. thus virtually eliminating any need for manual shifting.

This action alo e is enough to turn the turbine, which is connected to the car's propeller shaft. The amount of this boost or power multiplication varies automatically as the relative speeds of the fluid and of the pump and turbine change.
