2. Automatic transmission - Wikipedia

   en.wikipedia.org/wiki/Automatic_transmission

   This unit was an early semi-automatic transmission, based on the design of a conventional manual transmission, which used a servo-controlled vacuum-operated clutch system, with three different gear shifting modes, at the touch of a button; manual shifting and manual clutch operation (fully manual), manual shifting with automated clutch ...

3. Automated manual transmission - Wikipedia

   en.wikipedia.org/wiki/Automated_manual_transmission

   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 ...

4. Semi-automatic transmission - Wikipedia

   en.wikipedia.org/wiki/Semi-automatic_transmission

   An automated manual transmission may include a fully automatic mode where the driver does not need to change gears at all. [24] These transmissions can be described as a standard manual transmission with an automated clutch and automated gear shift control, allowing them to operate in the same manner as traditional automatic transmissions.

5. Transmission (mechanical device) - Wikipedia

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

   In the early mass-produced automobiles, the standard transmission design was manual: the combination of gears was selected by the driver through a lever (the gear stick) that displaced gears and gear groups along their axes. Starting in 1939, cars using various types of automatic transmission became available in the US market. These vehicles ...

6. Manumatic - Wikipedia

   en.wikipedia.org/wiki/Manumatic

   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 specific time. This is usually achieved using "+" and "-" positions on the gear selector or with paddle-shifters mounted beside the steering wheel.

7. Torque converter - Wikipedia

   en.wikipedia.org/wiki/Torque_converter

   In a vehicle with an automatic transmission, the torque converter connects the prime mover to the automatic gear train, which then drives the load. It is thus usually located between the engine's flexplate and the transmission. The equivalent device in a manual transmission is the mechanical clutch.

8. List of ZF transmissions - Wikipedia

   en.wikipedia.org/wiki/List_of_ZF_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; Basically there are two types of engine installation:

9. Easytronic - Wikipedia

   en.wikipedia.org/wiki/Easytronic

   The Easytronic system allows for a computer to assume control of the manual gearbox and clutch via electromechanical means. As of Easytronic 3.0, [2] the gearbox can be operated in either fully-automatic or sequential semi-automatic mode. In the former, the car behaves much like a traditional automatic transmission, selecting gears with no ...
