Options from the Hydra-Matic involved a wide unfold of ratios (permitting both excellent acceleration in initial gear and cruising at lower motor pace in major equipment) along with the fluid coupling managing only a percentage of the engine's torque in the highest two gears (growing gas overall economy in Those people gears, similar to a lock-up torque converter).
