  • List of ZF transmissions


    This list of ZF transmissions details those automotive transmissions created by the German ZF Friedrichshafen AG engineering company. There are two fundamental types of motor vehicle transmission: Manual — the driver has to perform each gear change Automatic — once placed in drive (or any other 'automatic' selector position), it selects the gear ratio dependent on engine speed and load automatically.Furthermore, they may also be manufactured solely as a gearbox, and use an entirely separate final drive unit (including its differential) – or be supplied as a transaxle, which includes both the gearbox and final drive unit within one housing.

  • Transaxle

  • Manual transmission

It uses a driver-operated clutch, usually engaged and disengaged by a foot pedal or hand lever, for regulating torque transfer from the engine to the transmission; and a gear selector that can be operated by hand or foot. A conventional 5-speed manual transmission is often the standard equipment in a base-model vehicle, while more expensive manual vehicles are usually equipped with a 6-speed transmission instead; other options include automatic transmissions such as a traditional automatic (hydraulic planetary) transmission (often a manumatic), a semi-automatic transmission, or a continuously variable transmission (CVT). The number of forward gear ratios is often expressed for automatic transmissions as well (e.g., 9-speed automatic).
