A gear stick (rarely spelled gearstick ), [1] [2] gear lever (both UK English ), gearshift or shifter (both U.S. 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 ...
Automated manual. v. t. e. Gear selection lever on the steering column of a 1934 Daimler Fifteen. A preselector gearbox is a type of manual transmission mostly used on passenger cars and racing cars in the 1930s, in buses from 1940–1960 and in armoured vehicles from the 1930s to the 1970s. The defining characteristic of a preselector gearbox ...
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 ...
Later cars used both a foot pedal and a hand lever to set the minimum throttle. The 1918 Stutz Bearcat had a central throttle pedal with the clutch and brake to the right and left. Modern cruise control was invented in 1948. Transmission A floor-mounted gear lever in a modern passenger car with a manual transmission
The M6 Presto-Matic was a Chrysler Corporation semi-automatic transmission produced from 1946 to 1953. It was a special manual transmission with a fluid coupling. Although it had just two forward gears, an electric overdrive unit was attached and useful in either gear for a total of four forward speeds. The driver would use the clutch pedal any ...
Design and operation. 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, electro-mechanical, pneumatic, electromagnetic ...
In addition to the 5-speed manual transmission, a 6-speed manual and 5-speed SMT were made available starting in 2002. A form of automated manual transmission, the SMT has no conventional H-pattern shift lever nor clutch pedal. The driver shifts gears by tapping the shift lever forward or backward or by pressing steering-wheel-mounted buttons.
A non-synchronous transmission, also called a crash gearbox, is a form of manual transmission based on gears that do not use synchronizing mechanisms. They require the driver to manually synchronize the transmission's input speed (engine RPM) and output speed (driveshaft speed). Non-synchronous transmissions are found primarily in various types ...
