The Creusot steam hammer was a giant steam hammer built in 1877 by Schneider and Co. in the French industrial town of Le Creusot.
 With the ability to deliver a blow of up to 100 tons, the Creusot hammer was the most powerful in the world until 1891, when the Bethlehem Iron Company of the United States purchased patent rights from Schneider and built a steam hammer of almost identical design but capable of delivering a 125-ton blow.
The Hammer was an automobile built in Detroit, Michigan by the Hammer Motor Company from 1905-06.
 The Hammer was a light car built with a two-cylinder, 12 hp engine in 1905.
 This was replaced with a 24 hp, four-cylinder engine for 1906.
 The five-seater tonneau weighted 1,800 lbs, and came with a choice of a planetary or sliding-gear transmission, with a shaft final drive.
 The Hammer Motor Company was formed as part of the Hammer-Sommer when they became defunct in 1905.
Multimode Manual Transmission (MMT or M/M, also Multimode Transmission) is a type of sequential manual transmission offered by Toyota.
 It uses a traditional manual gearbox with an electronically controlled clutch.
 Multimode Manual Transmission is available in the Aygo, Yaris, Corolla, Corolla Verso, Mark X and Auris in Europe, and should not be confused with Multimode Automatic Transmission, which is offered in the North American market by Toyota.
A semi-automatic transmission (SAT) (also known as a clutchless manual transmission, automated manual transmission, trigger shift, flappy-paddle gear shift, or paddle-shift gearbox) is an automobile transmission that does not change gears automatically, but rather facilitates manual gear changes by dispensing with the need to press a clutch pedal at the same time as changing gears.
 It uses electronic sensors, pneumatics, processors and actuators to execute gear shifts on input from the driver or by a computer.
 This removes the need for a clutch pedal which the driver otherwise needs to depress before making a gear change, since the clutch itself is actuated by electronic equipment which can synchronise the timing and torque required to make quick, smooth gear shifts.
 The system was designed by automobile manufacturers to provide a better driving experience through fast overtaking maneuvers on highways.
 Some motorcycles also use a system with a conventional gearchange but without the need for manual clutch operation.
The 1941 M4 Vacamatic transmission by Chrysler was, historically, the first semi-automatic transmission which was marketed by a major manufacturer.
 It was an attempt to compete against rivals' automatic transmissions, though it still had a clutch, primarily to change range.
 In normal driving, the clutch is not used.
 The transmission itself was a fully synchronised manual type, with four forward gears, one reverse; where the shifting was done 'automatically' by either vacuum cylinders (early, M4), or hydraulic cylinders (late, M6, Presto-Matic).
 The main difference was the addition of a fluid coupling between engine and clutch, and the shifting mechanism.
Automatic Manual Transmission (AMT) is a type of automatic sequential manual transmission.
 Offered by Renault Group's Dacia under the Easy-R name it is founded on electro-mechanical rather than hydraulic technology.
 Easy-R automated transmission uses a traditional manual gearbox with an electronically controlled clutch and eliminates the need for a clutch pedal.
Roto Hydramatic (sometimes spelled Roto Hydra-Matic or Roto-Hydramatic) was an automatic transmission built by General Motors and used on some Oldsmobile and Pontiac and Holden models from 1961–1965.
 It was based on the earlier, four-speed Hydramatic, but was more compact, providing only three forward speeds plus a small 8" fluid coupling with a stator inside of the fluid coupling.
 Oldsmobile, one of the users of this transmission, called the fluid couplings stator the "Accel-A-Rotor."
 The lightweight, aluminum-cased transmission was sometimes nicknamed the "Slim Jim."
 HydraMatic Division calls the Roto a four range, three gear HydraMatic.
 It counts the stator multiplication @ 3.50 to one as a first gear, and when road speed and the two coupling halves speed match, it counts the same gear with fluid now passing straight through the stator as 2nd gear at 2.93 to one.
 Second gear (or third range) has a ratio of 1.56 and because the fluid coupling is drained for this gear ratio making the front clutch apply makes this a rare automatic that is in FULL mechanical lock-up (coupling drained) in second gear.
 Fourth range the coupling fills releasing the front clutch makes a ratio of 1 to 1.
 This transmission, like single and dual range, and dual coupling hydramatics also have the feature of split torque in the transmission whereby in fourth or high gear only 40-to 50% depending on transmission, 40% in Roto's case, but because of the design the coupling is only required to carry 40% of the engine torque.
 The rest is (60%) is in full mechanical connection making these hydramatics the most efficient automatic until the wide spread use of the lock-up torque converter.
Electrohydraulic manual transmission is a type of semi-automatic transmission system, which uses an automated clutch unlike conventional manual transmissions where the driver operates the clutch.
 The clutch is controlled by electronic computers and hydraulics.
 To change gears, the driver selects the desired gear with the transmission shift lever, and the system automatically operates the clutch and throttle to match revs and engage the clutch again.
 Also, many such transmissions operate in sequential mode where the driver can only upshift or downshift by one gear at a time.
A manual transmission, also known as a manual gearbox, stick shift, "n"-speed manual (where "n" is its number of forward gear ratios), standard, MT, or in colloquial U.S. English, a stick (for vehicles with hand-lever shifters), is a type of transmission used in motor vehicle applications.
 It uses a driver-operated clutch engaged and disengaged by a foot pedal (automobile) or hand lever (motorcycle), for regulating torque transfer from the engine to the transmission; and a gear selector operated by hand (automobile) or by foot (motorcycle).
The 6L80 (and similar 6L90) is a six-speed automatic transmission built by General Motors at its Willow Run Transmission plant in Ypsilanti, MI.
 It was introduced in late 2005, and is very similar in design to the smaller 6L45/6L50, produced at GM Powertrain in Strasbourg, France.
 It features clutch to clutch shifting, eliminating the one-way clutches used on older transmission designs.
 In February 2006 GM announced that it would invest $500 million to expand the Toledo Transmission plant in Toledo, Ohio to produce the 6L80 in 2008.
