Automatic transmission in the context of "Transmission (mechanics)"

The M18 Hellcat (officially designated the 76 mm Gun Motor Carriage M18 or M18 GMC) was a tank destroyer used by the United States Army in World War II and the Korean War. Despite being equipped with the same main gun as some variants of the much larger Sherman tank, the M18 attained a much higher top speed of up to 55 mph (89 km/h) by keeping armor to a minimum, and using the innovative Torqmatic automatic transmission.

The M18 Hellcat was the culmination of the development of various prototypes of fast tank destroyers dating back to 1941. Entering production in summer 1943, the M18 first saw combat service in spring 1944. The M18 served primarily in Western Europe, but was also present in smaller numbers in Italy and the Pacific. Production continued until October 1944, with 2,507 built.

Hydramatic (also known as Hydra-Matic) is an automatic transmission developed by General Motors Corporation's Oldsmobile Division, the Hydramatic was the first mass-produced fully automatic transmission developed for passenger automobile use. The Hydra-Matic transmission was introduced by Oldsmobile in 1939 for the 1940 model year, one year before Cadillac.

An automatic transmission system (ATS) is an automated system designed to keep a broadcast radio or television station's transmitter and antenna system running without direct human oversight or attention for long periods. Such systems are occasionally referred to as automated transmission systems to avoid confusion with the automatic transmission of an automobile.

A gear stick (rarely spelled gearstick), gear lever (both UK English), gearshift or shifter (both US English), more formally known as a transmission lever, is a metal lever attached to the transmission of an automobile. The term gear stick mostly refers to the shift lever of a manual transmission, while in an automatic transmission, a similar lever is known as a gear selector. A gear stick will normally be used to change gear whilst depressing the clutch pedal with the left foot to disengage the engine from the drivetrain and wheels. Automatic transmission vehicles, including hydraulic (torque converter) automatic transmissions, automated manual and older semi-automatic transmissions (specifically clutchless manuals), like VW Autostick, and those with continuously variable transmissions, do not require a physical clutch pedal.

Car controls are the components in automobiles and other powered road vehicles, such as trucks and buses, used for driving and parking.

While controls like steering wheels and pedals have existed since the invention of cars, other controls have developed and adapted to the demands of drivers. For example, manual transmissions became less common as technology relating to automatic transmissions became advanced.

A torque converter is a device, usually implemented as a type of fluid coupling, that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. 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 usually located between the engine's flexplate and the transmission. The equivalent device in a manual transmission is the mechanical clutch.

A torque converter serves to increase transmitted torque when the output rotational speed is low. In the fluid coupling embodiment, it uses a fluid, driven by the vanes of an input impeller, and directed through the vanes of a fixed stator, to drive an output turbine so that torque on the output is increased when the output shaft is rotating slower than the input shaft, thus providing the equivalent of an adaptive reduction gear. This is a feature beyond what a simple fluid coupling provides, which can match rotational speed but does not multiply torque.

The automated manual transmission (AMT) is a type of transmission for motor vehicles. It is essentially a conventional manual transmission equipped with automatic actuation to operate the clutch and/or shift gears.

Many early versions of these transmissions that are semi-automatic in operation, such as Autostick, which automatically control only the clutch – often using various forms of clutch actuation, such as electro-mechanical, hydraulic, pneumatic, or vacuum actuation – but still require the driver's manual input and full control to initiate gear changes by hand. These systems that require manual shifting are also referred to as clutchless manual systems. Modern versions of these systems that are fully automatic in operation, such as Selespeed and Easytronic, can control both the clutch operation and the gear shifts automatically, by means of an ECU, therefore requiring no manual intervention or driver input for gear changes.

The Rolls-Royce Phantom V is a large four-door limousine produced by Rolls-Royce Limited from 1959 to 1968. Based on the Silver Cloud II, it shares a V8 engine and Rolls-Royce Hydramatic automatic gearbox (manufactured under license from General Motors by Rolls-Royce) with that model. Rolls-Royce built the cars' chassis and drivetrains, with bodies mainly made to standard designs by coachbuilders Park Ward, Mulliner Park Ward and James Young, former vendors absorbed by Rolls-Royce. Other coachbuilders, including Hooper, Henri Chapron and Woodall Nicholson, built one or two bodies each on Phantom V chassis.

The engine is a 6,230 cc 90-degree V8 with twin SU carburettors, coupled to a 4-speed automatic transmission. The car has massive drum brakes and a wheelbase of 3,683 mm. Power assisted steering was standard.
