  2. Dual-clutch transmission - Wikipedia

    en.wikipedia.org/wiki/Dual-clutch_transmission

    Schematic of a DCT (using two identical clutches located on the axis of the flywheel) A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. [1]

  3. Direct-shift gearbox - Wikipedia

    en.wikipedia.org/wiki/Direct-shift_gearbox

    A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.

  4. Automatic transmission - Wikipedia

    en.wikipedia.org/wiki/Automatic_transmission

    A dual-clutch transmission (DCT, sometimes referred to as a twin-clutch transmission, or double-clutch transmission) uses two separate clutches for odd and even gear sets. [37] The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit.

  6. Shift time - Wikipedia

    en.wikipedia.org/wiki/Shift_time

    Historically, a dual-clutch transmission shifts faster than a standard hydraulic automatic transmission with a torque converter or a single-clutch automated manual transmission. This is possible because the DCT can pre-select the next gear and transfer torque from one clutch to the next clutch with the pre-selected next gear, thus reducing ...

  7. Manual transmission - Wikipedia

    en.wikipedia.org/wiki/Manual_transmission

    In many light-duty vehicles, skilled drivers can slip the clutch just barely enough to hold the vehicle from much rollback during the second while the right foot is moving from the brake pedal to the accelerator pedal; this method effectively solves the hill-holding problem without any parking brake use and with negligible clutch life reduction ...

  8. Ford PowerShift transmission - Wikipedia

    en.wikipedia.org/wiki/Ford_PowerShift_transmission

    The operation of a dual-clutch transmission is analogous to two traditional manual transmissions, each with its own clutch, operating in parallel and alternating shifts. The Ford unit is a six-speed with one clutch acting on reverse, first, third, and fifth gears, and the other used for second, fourth, sixth gears.

  9. Continuously variable transmission - Wikipedia

    en.wikipedia.org/wiki/Continuously_variable...

    A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. [1] This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.
