What TREMEC makes

TREMEC designs and manufactures high-performance drivetrains and torque-transfer systems for conventional and electric vehicles. The core of the business is transmissions: 6-speed and 7-speed rear-wheel-drive manual gearboxes and dual-clutch transmissions built for OEM programs, plus an 8-speed dual-clutch transaxle developed for mid- and rear-engine performance cars. On the electrified side, TREMEC builds a dual-motor electric drive unit and a hybrid P2 module, along with the drivetrain components and controls that go with them: gears and shafts, mechatronic systems, electric drive components, and control units and software.

The company describes itself as vertically integrated, running its own forging, machining, and heat-treatment operations rather than buying finished gears and cases. That integration is visible in the customer roster it serves: Tier 1 OEM work across light vehicle, commercial vehicle, off-highway, e-mobility, hybrids, marine, and defense markets. TREMEC also runs a large aftermarket business under its own brand, selling manual transmissions such as the T-5, TKO, TKX, TR-4050, and the Magnum, Magnum-F, and Magnum-XL 6-speeds to builders and racers, plus transmission components, clutch assemblies, and fluid.

TREMEC's engineering heritage is muscle cars. The company's own materials describe it as "rooted in powering the Detroit Three's legendary muscle cars," and its transmissions can be found in a large share of rear-wheel-drive performance vehicles on the market. The current OEM lineup spans manual, dual-clutch, and electrified propulsion, which lets TREMEC offer an automaker a single drivetrain partner across an internal-combustion model and its electric successor.

Financial performance

TREMEC reports about $500 million in annual turnover and more than 2,400 employees worldwide, per the "At a Glance" figures on its own About page. It has been in operation since 1964. The company does not publish a standalone balance sheet, because it reports through its parent, Grupo KUO, rather than as an independent filer.

Those published figures put TREMEC well above the small-to-mid private suppliers that make up much of the North American parts base. Its scale, four-plus manufacturing sites across three countries, a $500M revenue base, and a workforce in the thousands, is the profile of an established mid-market OEM supplier rather than a single-plant job shop.

Ownership and history

TREMEC, short for Transmisiones y Equipos Mecanicos, was founded in Mexico in 1964 and built its reputation supplying manual transmissions for American performance cars. It is a wholly owned business of Grupo KUO, S.A.B. de C.V., a Mexican industrial conglomerate listed on the Bolsa Mexicana de Valores. The "S.A.B." in the name marks it as a publicly traded company, which means TREMEC sits inside a listed group rather than a privately held one, an ownership backing most independent suppliers do not have.

The company operates from a global headquarters in Santiago de Queretaro, Mexico, where it runs engineering, manufacturing, and assembly, with a second Mexican manufacturing plant in Pedro Escobedo. Outside Mexico it operates an engineering and manufacturing facility in Zedelgem, Belgium, and a US site in Wixom, Michigan, with corporate offices in Novi, Michigan. In August 2023, TREMEC acquired Electric GT, an EV systems provider, to expand its turn-key internal-combustion-to-battery-electric conversion offerings, a move that extended the company from transmissions into full electric drivetrain integration.

Certifications and quality

TREMEC's plants hold IATF 16949, the primary quality-management standard for the automotive industry. Its Zedelgem, Belgium facility was awarded IATF 16949 by Bureau Veritas in December 2018 for the design and manufacturing of manual and mechatronic transmissions, and the company states that its Queretaro and Pedro Escobedo, Mexico facilities have been certified since 2006 under the standard and its ISO/TS 16949 predecessor. TREMEC's heat-treat departments were recognized with a General Motors "Supplier Quality Excellence" distinction for 2020, per trade coverage.

The company runs a formal supplier-quality program of its own, publishing purchase terms and conditions, a Supplier Quality Assurance Manual, and a quality, safety, and environmental policy for its supply base. Suppliers to TREMEC are evaluated on standards compliance, financial stability, health-and-safety, and intellectual-property risk, the kind of structured supplier management expected of an OEM-facing manufacturer.

Known customers

TREMEC supplies transmissions to major automakers on documented programs. Its clearest OEM relationship is with General Motors:

Beyond these programs, TREMEC's own materials describe its transmissions appearing "in nearly every rear-wheel-drive application on the market," and the company says it exports products to more than 70 countries.

Sourcing evidence

TREMEC's US import record reads like a transmission manufacturer's, not a distributor's. It has 4,028 US import shipments on record, with activity current as of September 25, 2026, and its most active foreign suppliers are precision-driveline names: Schaeffler Technologies and SKF (bearings) and Miba Steeltec (sintered and forged steel components). That mix, bearings and precision steel in, finished transmissions out, is the signature of a company that machines and assembles gearboxes domestically and imports the specialized components that go inside them.

A monthly shipment time series was not available from the free customs record, so no trend chart is published here; the shipment count and recency come from the summary view.

Coverage caveats: these are US ocean-freight import records only. Air, truck, and rail movements, including cross-border flows between TREMEC's Mexican plants and the US, do not appear, and some records name freight intermediaries rather than manufacturers. Absence of a record is not evidence of absence. Buyers weighing nearshoring and tariff exposure should note that TREMEC's manufacturing base sits largely in Mexico, inside the North American production footprint.
