Overview
TREMEC Corporation is a drivetrain-technology manufacturer headquartered in Santiago de Querétaro, Mexico. Its principal business is the design and production of vehicle transmissions and related torque-transfer systems. The company serves a broad range of applications, from high-performance sports cars and supercars to passenger vehicles, vocational equipment, medium- and heavy-duty trucks, and other commercial vehicles. The company was established on April 12, 1964, during a period when Mexico used local-content and import-protection rules requiring vehicles assembled in the country to use domestically manufactured engines and transmissions. TREMEC was created through a joint venture involving Clark Transmissions, a major Ford transmission supplier, and two Mexican entrepreneurial companies. Its initial purpose was to manufacture transmissions in Mexico for Ford, General Motors, and Chrysler. Production began later in 1964. TREMEC's product portfolio has expanded well beyond conventional manual gearboxes. It includes manual transmissions, dual-clutch transmissions, gears, driveshafts, clutches, mechatronic systems, transmission control units, control software, and hybrid and electric-vehicle drivetrain solutions. The company is particularly associated with manual transmissions used in performance-oriented cars and with high-torque transmission programs for demanding commercial applications. Products such as the T-56, TR-6060, Magnum, TKX, and TR-9070 and TR-9080 dual-clutch families represent different stages of this development. Several early TREMEC products were based on designs originating with Borg-Warner, including the T-56 family. Over time, the company developed its own manufacturing, engineering, and aftermarket presence, while continuing to supply original-equipment manufacturers. Its aftermarket range allows replacement, restoration, and performance-vehicle builders to obtain manual transmissions and related components outside the original vehicle-production cycle. TREMEC operates manufacturing facilities in Mexico and Belgium. Mexican operations include sites in Pedro Escobedo and Santiago de Querétaro. Its European facility in the Zedelgem area near Bruges, Belgium, supports production and research and development. The company's United States operations are based in Novi, Michigan, where sales, marketing, and engineering functions are located and where the TR-9080 dual-clutch transmission is assembled. The U.S. base was previously located in Plymouth, Michigan, before moving to Novi in 2017. TREMEC is a wholly owned subsidiary of KUO Group, a diversified Mexican business group headquartered in Mexico City. The company therefore operates as a privately held industrial subsidiary rather than as an independently listed public company. Its positioning combines specialized transmission engineering, production scale, and application knowledge across performance, conventional, commercial, and emerging electrified drivetrains.

History
TREMEC was founded in Mexico on April 12, 1964. Its creation reflected Mexican industrial policy that required vehicles assembled in the country to use engines and transmissions manufactured domestically. To meet that requirement and establish a local transmission industry, a joint venture was formed involving Clark Transmissions, one of Ford's important transmission suppliers, together with two Mexican entrepreneurial companies. The new business was intended to supply transmissions for Ford, General Motors, and Chrysler programs in Mexico, and its first transmissions were produced later in the same year. The company operated under the TREMEC name, derived from Transmisiones y Equipos Mecánicos, and has also been associated with the corporate descriptions Transmission Technology Corporation and TTC. Its early operations established a Mexican manufacturing base for automotive transmissions at a time when the country's automotive sector was being developed behind significant local-content protections. A major part of TREMEC's later identity came from manual transmissions used in performance vehicles. Some early products were based on technology originally designed by Borg-Warner. The T-56 became one of the best-known examples of this lineage and was used broadly in high-performance applications. TREMEC subsequently manufactured and marketed a range of original-equipment and aftermarket manual transmissions, including the T-5, T-45, TKO, T-3550, TR-3650, and related families. Its aftermarket offerings gave the brand a strong presence among restoration projects, motorsport users, custom builders, and enthusiasts seeking replacement or higher-performance gearboxes. Alongside manual transmissions, TREMEC developed products for original-equipment vehicle manufacturers and commercial-vehicle customers. Its portfolio came to include transmissions for passenger cars, sports cars, trucks, vocational vehicles, and other severe-duty applications. The company also expanded into components and systems surrounding the gearbox, including gears, driveshafts, clutches, mechatronic assemblies, transmission control units, and software. The company later added dual-clutch transmission capabilities, including the seven-speed TR-9070 and eight-speed TR-9080 families. These products broadened TREMEC's role from a specialist manual-transmission supplier to a wider drivetrain technology provider. Its stated portfolio also includes hybrid and electric-vehicle solutions, reflecting the industry's movement toward electrified propulsion and electronically controlled torque-transfer systems. TREMEC's industrial footprint spans Mexico, the United States, and Belgium. Production facilities are located in Pedro Escobedo and Santiago de Querétaro, Mexico, and in the Zedelgem area near Bruges, Belgium. The Belgian site supports research and development as well as manufacturing. In the United States, the company operates from Novi, Michigan, with sales, marketing, and engineering activities and assembly of the TR-9080 dual-clutch transmission. The U.S. operation was located in Plymouth, Michigan, until its move to Novi in 2017. Engineering activities are also conducted in Querétaro. TREMEC is currently described as a wholly owned subsidiary of KUO Group, whose headquarters are in Mexico City. This ownership structure places the transmission manufacturer within a diversified Mexican industrial group. TREMEC's present business spans original equipment, aftermarket performance products, commercial transmissions, and newer hybrid and electric drivetrain technologies.
