A sub transmission for automotive transmission mechanics is an extra manual or automatic transmission that is independent of the main transmission. In a four-wheel drive vehicle, an extra gear stick is often provided to transfer torque when needed and to put the vehicle into low range.[ citation needed ] Sub transmissions are used in a few motorcycles, such as the Honda CB900C and the Honda CT110. In the Mitsubishi Cordia, a Super Shift 4x2 sub transmission was adopted, doubling the number of 4-speed main transmission gears.
The Honda Integra, sold in North America as the Acura Integra and later the Acura RSX, is an automobile produced by the Japanese company Honda from 1985 until 2006, and then since 2021. It succeeded the Quint as a more luxurious and sport-oriented derivative of the Civic. The Integra was one of the launch models for Acura in the US in 1986 alongside the Acura Legend. Throughout its production run, the Integra was highly regarded for its handling and performance. The 1995–2001 Integra Type R is widely regarded as one of the best front-wheel-drive cars of all time.
The Honda Insight is a hybrid electric vehicle that is manufactured and marketed by Honda. Its first generation was a two-door, two passenger liftback (1999–2006) and in its second generation was a four-door, five passenger liftback (2009–2014). In its third generation, it became a four-door sedan (2018–2022). It was Honda's first model with Integrated Motor Assist system and the most fuel efficient gasoline-powered car available in the U.S. without plug-in capability for the length of its production run.
The Acura TL is a car that was manufactured by Acura, the North American luxury division of Honda. It was introduced in 1995 to replace the Acura Vigor and was badged for the Japanese-market from 1996 to 2000 as the Honda Inspire and from 1996 to 2004 as the Honda Saber. The TL was Acura's best-selling model until it was outsold by the MDX in 2007. In 2005, it ranked as the second best-selling luxury sedan in the United States behind the BMW 3 Series, but sales decreased after the 2008 model year. Four generations of the Acura TL were produced, with the final fourth generation TL premiering in 2008 as a 2009 model and ending production in 2014, when it was replaced together with the TSX by the TLX.
Overdrive is the operation of an automobile cruising at sustained speed with reduced engine speed (rpm), leading to better fuel consumption, lower noise, and lower wear. The term is ambiguous. The most fundamental meaning is that of an overall gear ratio between engine and wheels, such that the car is over-geared, and cannot reach its potential top speed, i.e. the car could travel faster if it were in a lower gear, with the engine turning at higher RPM.
A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant angular velocity while the vehicle moves at varying speeds.
A manual transmission (MT), also known as manual gearbox, standard transmission, or stick shift, 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.
A transfer case is an intermediate gearbox that transfers power from the transmission of a motor vehicle to the driven axles of four-wheel-drive, all-wheel-drive, and other multi-axled on- and off-road machines. A part of the vehicle's drivetrain, it employs drive shafts to mechanically deliver motive power. The transfer case also synchronizes the difference between the rotation of the front and rear wheels, and may contain one or more sets of low range gears for off-road use.
A semi-automatic transmission is a multiple-speed transmission where part of its operation is automated, but the driver's input is still required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were almost exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets.
A drive shaft, driveshaft, driving shaft, tailshaft, propeller shaft, or Cardan shaft is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them.
The modern usage of the automotive term manumatic denotes an automatic transmission that allows the driver to select a specific gear, typically using paddle-shifters, steering wheel-mounted push-buttons, or "+" and "-" controls on the gear selector.
The Hondamatic was Honda's first semi-automatic transmission. It was produced from 1973 through 1988. The Hondamatic name continued to be used on fully-automatic transmissions from Honda.
A gear stick, gear lever, gearshift or shifter, 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 automatic transmissions, automated manual and older semi-automatic transmissions, like VW Autostick, and those with continuously variable transmissions, do not require a physical clutch pedal.
The Honda CB900C is a cruiser motorcycle produced by Honda from 1980 to 1982 primarily for the American market. It was succeeded by the CB1000C in 1983.
Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power, and can come in many configurations. For example, a hybrid may receive its energy by burning gasoline, but switch between an electric motor and a combustion engine.
Hero Motors is a former moped and scooter manufacturer based in Delhi, India. It is a part of multinational company Hero Motors Company, which also currently owns Hero Motocorp and Hero Cycles, among others. Hero Motors was started in the 1960s to manufacture 50 cc two-stroke mopeds but gradually diversified into making larger mopeds, mokicks and scooters in the 1980s and the 1990s. Noteworthy collaborators and technical partners were Puch of Austria and Malaguti of Italy manufacturing Puch Maxi Plus and Malaguti Centro respectively in India with updated engines.
The fourth-generation Honda Civic is a Japanese sub-compact automobile. It was produced by Honda from 1987 until 1991 with the wagon continuing in production in some markets until 1996. The suspension had a new double-wishbone suspension in the front and an independent suspension in the rear, the wheelbase was increased to 250 centimetres (98 in) from that of the third-generation Civic, and the body was redesigned with a lower hood line and more glass, resulting in less drag. The redesigned Civic was introduced in 1987 for the 1988 model year. The fourth-generation Civic would be available in three variants; 3-door hatchback, 4-door sedan and 5-door wagon with various trim levels offered in each variant.
The eighth-generation Honda Civic is a range of compact cars (C-segment) manufactured by Honda between 2005 and 2012, replacing the seventh-generation Civic. Four body styles were introduced throughout its production run, which are sedan, coupe, and both three-door and five-door hatchback. The sedan version was introduced with two distinct styling for different markets, with one of them sold as the Acura CSX in Canada and as the Ciimo 1.8 in China from 2012 until 2016. The hatchback versions formed the European-market Civic range, which received a different architecture, body design and smaller footprint, and solely produced in Swindon, United Kingdom.
A dual-clutch transmission (DCT) is a type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. In car and truck applications, the DCT functions as an automatic transmission, requiring no driver input to change gears.
The Honda Odyssey is a minivan manufactured by Japanese automaker Honda and marketed for the North American market. Introduced in 1994, the Odyssey is now in its fifth generation, which began in 2018.
A motorcycle transmission is a transmission created specifically for motorcycle applications. They may also be found in use on other light vehicles such as motor tricycles and quadbikes, go-karts, offroad buggies, auto rickshaws, mowers, and other utility vehicles, microcars, and even some superlight racing cars.
