An automatic transmission is a multi-speed transmission used in motor vehicles that does not require any driver input to change gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle.
A transmission is a machine in a power transmission system, which provides controlled application of power. Often the term 5-speed transmission refers simply to the gearbox, that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.
A manual transmission 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 Formula One car is a single-seat, open-cockpit, open-wheel racing car with substantial front and rear wings, and an engine positioned behind the driver, intended to be used in competition at Formula One racing events. The regulations governing the cars are unique to the championship and specify that cars must be constructed by the racing teams themselves, though the design and manufacture can be outsourced.
Semi-automatic transmission denotes a multi-speed motor vehicle transmission where part of its operation is automated, but the driver's input is still required to start from a standstill and to manually change gears. Most semi-automatic transmissions used in cars and motorcycles are based on conventional manual transmissions or a sequential manual transmission, but use an automatic clutch system. However, some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions, with a fluid coupling or torque converter.
A direct-shift gearbox, commonly abbreviated to DSG, is an electronically-controlled, dual-clutch, multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout, with automated clutch operation, and with fully-automatic or semi-manual gear selection. The first dual-clutch transmissions were derived from Porsche in-house development for the Porsche 962 in the 1980s.
Power Shift is an annual youth summit which has been held in New Zealand, Australia, Canada, the United Kingdom and the United States. Other Power Shift Conferences are also being organised by members of the International Youth Climate Movement including Africa, Japan and India. The focus of the events is on climate change policy.
Allison Transmission is an American manufacturer of commercial duty automatic transmissions and hybrid propulsion systems. Allison products are specified by over 250 vehicle manufacturers and are used in many market sectors including bus, refuse, fire, construction, distribution, military, and specialty applications.
A phase angle regulating transformer, phase angle regulator, phase-shifting transformer, phase shifter, or quadrature booster, is a specialised form of transformer used to control the flow of real power on three-phase electric transmission networks.
The Ford S-Max is an MPV produced by Ford Europe for the European market. Ford also describes the S-Max as an SAV. Introduced at the 2006 Geneva Motor Show, the S-Max went on sale alongside the new generation Galaxy in June 2006.
Powershifting, also known as full-throttle shifting or flat-shifting, is a method of shifting used with manual transmissions to reduce the time where the driving wheels are not powered. Unlike a normal gearchange, in a powershift the driver does not let off the accelerator. The clutch is briefly depressed while the shift lever is rapidly shifted into a higher gear, keeping the engine in its power band. Keeping the engine in its powerband allows it to put down power quicker when the clutch is "dropped" and power returns to the transmission. In most cases, there is a method of cutting the ignition or fuel delivery, in a manner similar to a rev-limiter, which prevents the engine from over-revving when the load from the transmission is removed. Many aftermarket engine management systems provide this functionality as either a standard feature or as an option, usually combined with launch control.
Shift time refers to the time interval between gear changes in a transmission. This interval is the time in which power delivery is interrupted and engine speed is reduced or increased to synchronize speed for the next selected gear. Shift time is usually in reference to motor vehicles but can apply to any gearbox. Reducing shift time is important in performance vehicles or race cars because the shifting process generally interrupts power delivery to the wheels. Shift time in a manual gearbox is dependent on the driver, but in automatic or automated manual cars the electronic or hydraulic control system must be calibrated and tuned to deliver a fast gear change.
A shift kit is a set of components for automobiles designed to improve how well the car shifts between gears. Kits are made for both automatic and manual transmissions.
Power Shift Network is a North American non-profit organization made up of a network of youth-led social and environmental justice organizations working together to build the youth clean energy and climate movement. It runs campaigns in the United States and Canada to build grassroots power and advocate for tangible changes on climate change and social justice at local, state, national and international levels in North America. The organization changed its name from Energy Action Coalition in July 2016 in order to reflect its new leadership and it shift from a coalition to a network structure. The Power Shift Network's members, which include other non-profit organizations and student groups focused on environmental justice, social justice, and climate change, focus their organizing and campaigns on campuses, communities, corporate practices, and politics. The Power Shift Network is part of the Global Youth Climate Movement.
Twin Clutch SST is the brand name of a six-speed dual-clutch automatic transmission, developed by Getrag for Mitsubishi Motors. The system was first incorporated in the 2008 Lancer Evolution X, and was designed to be a more performance-oriented system than that developed by rival manufacturers, with shorter gear ratios optimized for acceleration.
The Ford PowerShift is a six-speed dual-clutch automatic transmission, produced by the Ford Motor Company. The Ford PowerShift gearboxes were built by Getrag Ford Transmissions, a joint-venture with Getrag. PowerShift improves fuel efficiency by as much as 10 percent when compared to a conventional automatic transmission.
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 John Deere PowerShift transmission was an eight-speed semi-automatic transmission without a torque converter, used in John Deere tractors, including the iconic John Deere Model 4020. The Powershift is not to be confused with similar John Deere transmissions, or with the Ford Ultra Command Powershift or the Allis Chalmers Power Director. The PowerShift was dropped in favor of the PowrQuad during the 1980s and reintroduced in the 90s as a 16-speed model built by Funk, a company that was eventually purchased by John Deere. The 5-speed version was also used in the Ford 8630 series tractors as a 36-speed Funk Ultra Command.
The Volvo I-Shift is an automated manual transmission developed by Volvo subsidiary Volvo Powertrain AB for Volvo Trucks and Volvo Buses, with 12 forward gears and 4 reverse gears. It became available for trucks in 2001 and later buses in 2004.
