Daimler AG (today: Mercedes-Benz Group AG ) is a German car manufacturing company. It manufactures its own automobile transmissions and only purchases from suppliers in individual cases. They may be used in passenger cars and SUVs, or light commercial vehicles such as vans and light trucks.
Basically there are two types of motor vehicle transmissions:
Basically there are two types of engine installation:
Every type of transmission occurs in every type of installation.
For manual transmissions G for gearbox and two digits are used. See G56 — 6-speed manual as an example. In 2019, Daimler AG discontinued the production of manual transmissions.
Mercedes-Benz uses the number "720" to currently "725" to identify automatic, dual-clutch (DCT), Continuously variable (CVT), and automated manual transmissions (AMT).

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.
Mercedes-AMG GmbH, commonly known as AMG, is the high-performance subsidiary of Mercedes-Benz AG. AMG independently hires engineers and contracts with manufacturers to customize Mercedes-Benz AMG vehicles. The company has its headquarters in Affalterbach, Baden-Württemberg, Germany.
The Mercedes-Benz W210 is the internal designation for a range of executive cars manufactured by Mercedes-Benz and marketed under the E-Class model name in both sedan/saloon (1995–2002) and station wagon/estate (1996–2003) configurations. W210 development started in 1988, three years after the W124's introduction.
The Mercedes-Benz R107 and C107 are sports cars which were produced by Mercedes-Benz from 1971 until 1989, being the second longest single series ever produced by the automaker after the G-Class. They were sold under the SL (R107) and SLC (C107) model names in a variety of names indicating the displacement of the engines.
The Mercedes-Benz Atego is a range of general-purpose rigid trucks introduced by Daimler Truck in 1998. A new model was introduced in 2004, followed by a facelift in 2010 and another new model in 2013. The latest version is available in gross vehicle weights of 6.5 to 16 tonnes (t) and is powered by a straight 4- or 6-cylinder engine.
7G-Tronic is Mercedes-Benz's trademark name for its 7-speed automatic transmission, starting off with the W7A 700 and W7A 400 as core models.
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.
5G-Tronic is Mercedes-Benz's trademark name for its 5-speed automatic transmission, starting off with the W5A 580 and W5A 330 as core models.
Mercedes-Benz 4G-Tronic transmission is the unofficial name given to the transmission by car enthusiasts. It was produced from 1979 to 1996 in W4A 040, W4A 028, W4A 020, and W5A 030 variants.
The Mercedes-Benz GLA is a subcompact luxury crossover SUV manufactured and marketed by Mercedes-Benz over two generations. It is essentially the SUV equivalent of the A-Class, and the smallest SUV marketed by the brand. The production version was revealed in August 2013 ahead of the 2013 Frankfurt Auto Show in September 2013.
The third generation of Mercedes-Benz SLK-Class (SLC-Class) was launched in Stuttgart in January 2011, with a subsequent public launch at the 2011 Geneva Motor Show, with international sales starting spring 2011. It is the successor of R171 series of roadsters which was originally launched in 2004. The SLC was discontinued after the 2020 model year.
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.
9G-Tronic is Mercedes-Benz's trademark name for its 9-speed automatic transmission, starting off with the W9A 700 as core model. The transmission debuted on the E 350 BlueTEC in 2013, and successively replaced both the 7-speed 7G-Tronic (PLUS) transmission and the 5-speed 5G-Tronic transmission. It includes versions for a maximum input torque of 1,000 N⋅m (738 lb⋅ft).
The Mercedes-Benz GLB is a crossover SUV produced by Mercedes-Benz. It was unveiled by the German manufacturer Daimler AG on 10 June 2019 in Park City, Utah. It was previously unveiled as a concept car to the public at the Shanghai Auto Show in April 2019.
Mercedes-Benz W202 is the internal designation for a compact sedan/saloon manufactured and marketed by Mercedes-Benz between 1992 and 2001, as the first generation of the C-Class, now in its fifth generation. Replacing the 190 series/W201 in June 1993, the C-Class sedan was Mercedes' entry-level model until 1997, when the company launched the A-Class. Production reached 1,847,382 over model years 1994–2000.
The Mercedes-Benz first series of automatic transmission was produced from 1961 to 1983 in 4- and 3-speed variants for Mercedes-Benz passenger cars. In addition, variants for commercial vehicles were offered.
The Unimog 425 is the first series production heavy duty Unimog series, made by Daimler-Benz from 1975 to 1988 in the Mercedes-Benz Gaggenau plant, alongside the long-wheelbase model Unimog 435. It was first presented to the public on the 1974 DLG show in Frankfurt, then named Unimog U 120, indicating a power output of 120 PS. However, series production models were equipped with 125 PS or 150 PS engines, and therefore called U 1300 and U 1500. Daimler-Benz made three types of the Unimog 425, and a total number of 3135 were built, making the 425 much rarer compared to the longer wheelbase, but otherwise similar Unimog 435, of which more than 30,000 were built. The 425 was the first Unimog to feature the "edgy cab", which is still used in the Unimog today.
The Unimog 405 is a vehicle of the Unimog-series by Mercedes-Benz, made by Daimler Truck Holding AG. Developed in the 1990s, the Unimog 405 has been in production since 2000. Originally, DaimlerChrysler produced the Unimog at Gaggenau; in 2002, production was moved to Wörth am Rhein. The Unimog 405 is the implement carrier version of the Unimog and the successor to most previous Unimogs. Although retaining many characteristics typical of the Unimog, the 405's axle and chassis design concept with control arms instead of torque tubes marks a "paradigmatic change" in Unimog design.
