Automatic Transmission Were First Mass Produced in 1939

In 1939, General Motors first sold its HydraMatic gearbox. It was installed in Oldsmobile and Cadillac models. This was the first time that an automatic-style transmission was made widely available to the public.

Separate License for Manual in the U.K.

In the United Kingdom, if you pass your driver's test in an automatic transmission, you'll still have to get a separate certification with a manual before you can legally drive a stick shift. But if you pass your driver's test in a manual transmission, you'll also be certified to drive an automatic transmission.

The Preselector Gearbox

Between the 1930s and 1950s, the preselect transmission was rather common. With this type of transmission, the driver would select the gear to which they wanted to shift before hitting the clutch pedal. Then, when the clutch became engaged, the car would automatically shift to the chosen gear.

Automatics Can Now Get Similar or Better Gas Mileage than Manuals

It's widely believed that manuals get better MPGs than automatics. In years past, this was true. But modern automatic transmission technology has advanced to the point that manual models get the same or better gas mileage as their manual counterparts.
