The transmission was delicate to engine throttle place and highway pace, manufacturing totally automatic up- and down-shifting that diverse In keeping with working situations. Characteristics from the Hydra-Matic bundled a large unfold of ratios (allowing the two very good acceleration in first equipment and cruising at low engine speed in leading equipment) plus the fluid coupling managing just a percentage of the motor's torque in the top two gears (raising gasoline economic climate in Individuals gears, much like a lock-up torque converter).
Hence the rotation is destructive 2.four:one, which means the output path will be reverse the input path. Even so the output route is de facto the same as the enter direction -- This is when the trick Together with the two sets of planets is available in.
