TREMEC (Transmisiones y Equipos Mecánicos SA de CV, formerly Transmission Technology Corporation, TTC) is a manufacturer of automobile transmissions and drivetrain components based in Querétaro, Mexico.
Torque transfer solutions from TREMEC are found in products ranging from supercars and high-performance sports cars to severe duty, vocational and commercial vehicles worldwide. The portfolio of products includes manual transmissions, dual-clutch transmissions, hybrid and electric vehicle (EV) solutions,[ buzzword ] gears, driveshafts, clutches, mechatronic systems, transmission control units, and control software.
The company is headquartered in Santiago de Querétaro, Mexico and has its US operations based in Novi, Michigan. This location assembles the TR-9080 Dual Clutch Transmission as well as housing sales, marketing and engineering (and was, until 2017, based in Plymouth, Michigan). Production facilities are also located in Pedro Escobedo and Santiago de Querétaro, in Mexico, and Zedelgem (Bruges area) in Belgium. Research and Development is based in the Belgium location and engineering is also located in Queretaro. TREMEC is a wholly owned subsidiary of KUO Group, which is based in Mexico City. [1]
Some of the first TREMEC products were originally designed by Borg-Warner, including the widely used T-56.
TREMEC was founded on April 12, 1964. The genesis was to manufacture transmissions in Mexico for Ford, GM and Chrysler. At that time, the Mexican government enacted a protectionist policy that mandated all vehicles assembled in Mexico have engines and transmissions 100-percent manufactured in Mexico. A joint venture was formed which included one of Ford's large transmissions suppliers – Clark Transmissions – and two entrepreneurial companies based in Mexico. TREMEC's first transmissions would be produced later that same year. [2]
An automatic transmission is a multi-speed transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive the wheels over a wide range of speeds.
A transmission is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine.
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.
Getrag, stylized as GETRAG, was a major supplier of transmission systems for passenger cars and commercial vehicles. The company was founded on 1 May 1935, in Ludwigsburg, Germany, by Hermann Hagenmeyer; as the Getriebe und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KG.
The T-56 six speed manual transmission has been used in a wide range of vehicles from General Motors, Dodge, and Ford Motor Company. The transmission was originally designed and built by BorgWarner for the Dodge Viper later being used by GM in 1992 for the generation II and later engines, but from 1998 was built by Tremec, though nothing changed internally. The T-56 has been succeeded by the Tremec TR-6060 transmission in many former T-56 applications, as well as applications requiring greater strength than the T-56 could offer.
A direct-shift gearbox 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.
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.
DEXRON is the trade name for a group of technical specifications for automatic transmission fluid (ATF) created by General Motors (GM). The name was first registered as a trademark and later evolved into a brand of GM. GM licenses the name and specifications to companies that manufacture the fluid and sell it under their own brand names. Not all DEXRON fluids are licensed by GM for reselling under another brand name. To be licensed, the product must have a license number that begins with the letters B through J and include a "DEXRON Approved" sticker on its container. Like many automobile manufacturers, GM uses transmissions sourced from other suppliers or transmission manufacturers around the world; many of these may use their own unique fluid.
The TREMEC TR-3650 is a 5-speed manual transmission for longitudinal engine automobiles. It includes a 5th gear that functions as an overdrive gear, light-weight aluminum housings, a synchromesh reverse gear, and synchromeshed helical cut forward gears. It is manufactured by Transmission Technologies Corporation and is rated for 360 lbf⋅ft (490 N⋅m) of torque. The loss in power transmission efficiency is rated at approximately 16% in 4th gear for a 2005–2010 Ford Mustang GT.
Shift time refers to the time interval between gear changes in a transmission. This interval is the time in which power delivery is transferred to the next selected gear, and engine speed is reduced or increased to synchronize the speed of the next gear. Shift time is usually in reference to motor vehicles, but can apply to any gearbox.
The Tremec TR-6060 six-speed manual transmission features six forward speeds and one reverse speed. It is derived from the Tremec T-56 6-speed manual transmission. As usual, the forward helical cut gears are synchronized. However, the reverse gear operates through a fully synchronized constant-mesh system. The TR-6060 contains removable wear pads on the shift forks, and uses aluminum alloys for the main case, extension housing, and clutch housing. It is a double overdrive transmission. The TR-6060 is manufactured by TREMEC and is rated for 430 lb⋅ft (580 N⋅m) to 650 lb⋅ft (880 N⋅m) of torque, depending on gearing.
The Hyundai Veloster is a compact car first produced in 2011 by Hyundai, with sales beginning in South Korea on March 10, 2011, and in Canada and the United States since the fall of 2011. In South Korea, it was marketed under Hyundai's 'Premium Youth Lab'. It was unveiled on January 10, 2011, at the Detroit Auto Show, and fills the void left when Hyundai discontinued the Hyundai Tiburon after the 2008 model year.
The Ford PowerShift is a six- or seven-speed dual-clutch automatic transmission, produced by the Ford Motor Company. The older Ford PowerShift gearboxes were built by Getrag Ford Transmissions, a joint-venture with Getrag, however it is unknown who exactly makes the newer 7-speed models. 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.
Dana Graziano is an Italian company based in Turin manufacturing gearboxes, drivelines and their mechatronics components. It makes the "Pre-Cog" seven-speed Seamless-Shift gearbox (SSG) dual-clutch transmission used in the McLaren 12C.
The TREMEC TR-6070 seven-speed RWD manual transmission features seven forward speeds and one reverse speed. It is manufactured by TREMEC Corporation.
The TREMEC TR-3160 is a six-speed RWD manual transmission that features six forward speeds and one reverse speed. It is manufactured by TREMEC.
