(automotive) A type of single-clutch automatic transmission that is closely based on the internal design and mechanical build and of a conventional manual transmission; but is computer-controlled, and does require any manual input from the driver to change gear or actuate the clutch.

(automotive) A multi-speed motor vehicle transmission where part of its operation is automated (typically the clutch actuation; partially automated) but the driver's input is still required to manually operate a gearshift and to change gear by hand/foot; i.e., not fully-automatic. Names for specific types of semi-automatic transmissions include clutchless manual, auto-manual, auto-clutch manual, and paddle-shift transmissions. These systems facilitate gear changes for the driver by operating the clutch system automatically, usually by means, or under control of an actuator or servo, sensors, a solenoid, and an integrated electronic control module, while still requiring the driver's input to manually shift gears.

(automotive) A manual transmission or a sequential manual gearbox without a manually-operated clutch (i.e., with an automatic clutch) system; used in both automobiles and motorcycles (i.e., mechanically the same as a conventional manual transmission, but lacks a physical clutch pedal). These systems facilitate the driver by automating the clutch system, but still require the driver's input to change gear manually, by means of a conventional manual gearshift. It is a form of semi-automatic transmission.

plural of transmission electron diffraction

(automotive) Any of several forms of automatic transmission, without specific gears, in which the gear ratio may be changed without any noticeable steps.
