The transmission was sensitive to motor throttle position and road speed, making entirely automatic up- and down-shifting that assorted As outlined by working problems. Capabilities on the Hydra-Matic incorporated a broad unfold of ratios (permitting both equally superior acceleration in initially gear and cruising at lower engine speed in top rated equipment) plus the fluid coupling dealing with only a percentage of the engine's torque in the best two gears (rising fuel financial system in These gears, comparable to a lock-up torque converter).
