List of Daimler AG transmissions

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:

Manual – the driver has to perform each gear change using a manually operated clutch
Automatic – once placed in drive (or any other 'automatic' selector position), it automatically selects the gear ratio dependent on engine speed and load

Basically there are two types of engine installation:

In the longitudinal direction, the gearbox is usually designed separately from the final drive (including the differential). The transaxle configuration combines the gearbox and final drive in one housing and is only built in individual cases
In the transverse direction, the gearbox and final drive are very often combined in one housing due to the much more restricted space available

Every type of transmission occurs in every type of installation.

Mercedes-Benz Manual Transmissions

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 Automatic Transmissions

Mercedes-Benz uses the number "720" to currently "725" to identify automatic, dual-clutch (DCT), Continuously variable (CVT), and automated manual transmissions (AMT).
