  2. Parking pawl - Wikipedia

    en.wikipedia.org/wiki/Parking_pawl

    A parking pawl is a device fitted to a motor vehicle's automatic transmission that locks up the transmission when the transmission shift lever selector is placed in the Park position.

  3. Automatic transmission - Wikipedia

    en.wikipedia.org/wiki/Automatic_transmission

    An automatic transmission (sometimes abbreviated AT) is a multi-speed transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first true automatic transmission.

  4. Transmission (mechanical device) - Wikipedia

    en.wikipedia.org/wiki/Transmission_(mechanical...

    A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...

  5. Semi-automatic transmission - Wikipedia

    en.wikipedia.org/wiki/Semi-automatic_transmission

    A semi-automatic transmission is a multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input is still required to launch the vehicle from a standstill and to manually change gears.

  6. Shift time - Wikipedia

    en.wikipedia.org/wiki/Shift_time

    Shift time refers to the time interval between gear changes in a transmission.This interval is the time in which power delivery is transferred to the next selected gear, and engine speed is reduced or increased to synchronize the speed of the next gear.

  7. GM 5L40-E transmission - Wikipedia

    en.wikipedia.org/wiki/GM_5L40-E_transmission

    The 5L40-E was designated in either "M82" (rear-wheel drive) or "MX5" (all-wheel drive) versions for service in BMW vehicles from 1999 model year until the design was superseded by (for BMW) the 6L45E and (for all others) the 6L50E series electronic automatic transmissions in 2007 . It is designed for service in vehicles up to 4000 lb (1814 kg ...

  8. Variomatic - Wikipedia

    en.wikipedia.org/wiki/Variomatic

    It is a stepless, fully-automatic transmission, consisting of a V-shaped drive-belt, and two pulleys, each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle or nearer the rim, depending on the separation of the cones. These are synchronized so that the belt always remains at the same optimal tension.

  9. Overdrive (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Overdrive_(mechanics)

    The propeller shaft linking gearbox and rear axle is thus overdriven, and a transmission capable of doing this became termed an "overdrive" transmission. [1] The device for achieving an overdrive transmission was usually a small separate gearbox, attached to the rear of the main gearbox and controlled by its own shift lever. [1]
