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 ...
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
The most common design of automatic transmissions is the hydraulic automatic, which typically uses planetary gearsets that are operated using hydraulics. [ 11 ] [ 12 ] The transmission is connected to the engine via a torque converter (or a fluid coupling prior to the 1960s), instead of the friction clutch used by most manual transmissions and ...

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.
The TH400 was phased out for the 1980 models, when the A-727 replaced the TH-400 as the only automatic transmission option for both the SJ Wagoneer/Cherokee wagons and the J-10/J-20 trucks. Internally similar to the Chrysler A-727, the case was one-piece, cast with an AMC pattern bellhousing (not interchangeable with a Chrysler pattern A-727).
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.
Manual shifting is allowed with the gear stick in the manual mode. The gear stick can also be used just like any other automatic gearbox, where the transmission will shift automatically. Geartronic is offered on Volvo vehicles with engine displacements of 2.0 liters or greater. Geartronic transmissions are manufactured in Japan by Aisin AW.
