Accessible as an alternative in automobiles like the Oldsmobile Sequence 60 and Cadillac Sixty Particular, the Hydra-Matic combined a fluid coupling with 3 hydraulically managed planetary gearsets to produce 4 ahead speeds as well as reverse. The transmission was sensitive to motor throttle posture and highway velocity, developing thoroughly automatic up- and down-shifting that assorted In accordance with functioning disorders. Attributes on the Hydra-Matic involved a broad unfold of ratios (letting both of those excellent acceleration in 1st gear and cruising at minimal engine velocity in top rated gear) as well as fluid coupling dealing with only a part of the engine's torque in the very best two gears (escalating gas financial system in People gears, comparable to a lock-up torque converter).
Previously versions of these transmissions which are semi-automatic in Procedure, for example Autostick, Regulate just the clutch process automatically — and use unique types of actuation (usually by means of an actuator or servo) to automate the clutch, but still involve the driving force's enter gearbox auto and full Handle to manually actuate equipment improvements by hand.

L/1 – L means Minimal gear. This method locks the automatic transmission in to start with equipment only. In more mature autos, it will likely not adjust to almost every other equipment selection.
