Hydramatics were dual range even in 1955 and back. This referred to the 2 drive positions on the quadrant. One was for country driving (1 to 1 ratio) the other was for city driving (1.5 to 1). I have a 1956 Pontiac Chieftain that uses the older version without the separate park position on the quadrant. The Chieftains got the older style transmission.
I believe the Jet-away I think was Oldsmobile's name for the Hydramatic. In the Pontiac they are known as Strato-Streak and Strato Flite.
They have to have the control rod adjusted just right between carb and transmission or they shift hard or slip going from gear to gear....
