The name Autostick has been used for a Volkswagen semi-automatic transmission, which is a vacuum-operated automatic clutch system, coupled with a conventional 3-speed manual transmission. The "AutoStick" system designed by Chrysler allows for manual selection of gears with a standard hydraulic automatic transmission, also known as a manumatic.[1]
The Autostick systems used by Volkswagen and Chrysler are unrelated, not mechanically similar in their operation, and do not share any similarities with their internal design and build.
The manumatic transmission systems are variously described or marketed under names that including "e-stick", "shift-command", "steptronic", and "geartronic".[2] Manufacturers increasingly offer electronically-controlled automatic transmissions that provide drivers with an ability to shift gears on their own.
The objective of these systems is to provide a sportier, more driver-focused feel.[3] They combine the convenience of an automatic with the ability for the driver to have an increased degree of control in gear selection process. Due to modern automatic transmissions becoming almost as efficient and responsive, cars with fully manual transmissions are less in demand.[3]
