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 ...

  3. Shift kit - Wikipedia

    en.wikipedia.org/wiki/Shift_kit

    For manual transmission equipped cars, it is a component that replaces the stock gear selector (shifter).

    The 9HP is only 0.24 inches (6 mm) longer than, and weighs 16.5 lbs (7.5 kg) less than, the outgoing six-speed transmission. The compact packaging is achieved by using a number of innovative design features: a new compact hydraulic vane-type pump, two patented dog clutches, [3] which replace bulkier conventional clutch packs, and a nested gear set.

    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.

  9. Start-stop system - Wikipedia

    en.wikipedia.org/wiki/Start-stop_system

    In a manual transmission vehicle, stop-start is activated by stopping the car, shifting the gear to neutral, and releasing the clutch. The engine will not stop if the car is moving, even if the aforementioned steps are followed (this is not true for all cars). The engine restarts when the clutch is pressed prior to selecting a gear to move the car.
