This was provided to allow engine braking on downhills or prevent the use of overdrive gears when towing and was typically achieved using positions such as "3", "2", and "1" on the gear selector. An automatic transmission with a manumatic function provides a greater level of control by allowing the driver to request an upshift or downshift at a ...
The evolution towards mass-produced automatic transmissions continued with the 1933–1935 REO Motor Car Company Self-Shifter semi-automatic transmission, [22] which automatically shifted between two forward gears in the "Forward" mode (or between two shorter gear ratios in the "Emergency low" mode).
Many transmissions – especially for transportation applications – have multiple gears that are used to change the ratio of input speed (e.g. engine rpm) to the output speed (e.g. the speed of a car) as required for a given situation. Gear (ratio) selection can be manual, semi-automatic, or automatic.
Basically there are two types of motor vehicle transmissions: Manual – the driver has to perform each gear change using a manually operated clutch; Automatic – once placed in drive (or any other 'automatic' selector position), it automatically selects the gear ratio dependent on engine speed and load
Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
The General Motors Automatic Safety Transmission (AST) was a semi-automatic transmission released in 1937. The first mass-produced fully-automatic transmission developed for passenger automobile use was the GM Hydra-Matic introduced in the autumn of 1939 as a (very likely subsidized) $57 option for the 1940 Oldsmobile.

The 1941 Chrysler M4 Vacamatic transmission was a two-speed manual transmission with an integral underdrive unit, a traditional manual clutch, and a fluid coupling between the engine and the clutch. [ 51 ] [ 52 ] [ 53 ] The two-speed transmission had "high" and "low" ranges, and the clutch was used when the driver wanted to switch between ranges.
Top and side view of a typical manual transmission, in this case, a Ford Toploader, used in vehicles with external floor shifters. The first car to use a manual transmission with synchromesh was the 1929 Cadillac. [5] Most North American marques had adopted synchronized manual transmissions, usually for second and high gears, by the mid-1930s.
