List of Daimler AG transmissions

From Wikipedia, the free encyclopedia

Daimler 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 motor cars (automobiles), or light commercial vehicles such as car-derived vans and light trucks.

There are two fundamental types of motor vehicle transmission:

  • Manual – the driver has to perform each gear change (i.e., the driver is required to shift gears) and also has a manually operated clutch to shift between gears.
  • Automatic – once placed in drive (or any other 'automatic' selector position), it selects the gear ratio dependent on engine speed and load automatically.

For longitudinal engines the gearboxes usually be manufactured solely as a gearbox, and use an entirely separate final drive unit (including its differential). Transaxle configuration includes both the gearbox and final drive unit within one housing and is built only in individual cases.

Mercedes-Benz Manual Transmissions

[edit]

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

[edit]

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