List of Aisin transmissions

Aisin is a Japanese corporation that develops and produces components and systems for the automotive industry, in particular automobile transmissions for passenger cars and SUVs, light commercial vehicles such as vans and light trucks. Aisin is a member of the Toyota Group of companies. Therefore, the transmissions of both manufacturers are often based on identical gearset concepts.

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.

Automatic transmissions

History

Aisin automatic transmissions are manufactured by Aisin-Warner (AW) which was established in 1969 as a joint venture between Aisin and BorgWarner. While Aisin Seiki manufactures a variety of automotive components including automatic transmissions for heavy duty vehicle applications, Aisin AW manufactures automatic transmissions for light vehicle applications, including hybrid electric vehicle powertrains, as well as NAV Radio.

As of 2005, Aisin AW surpassed General Motors Powertrain Division as the largest producer of automatic transmissions in the world, producing 4.9 million units, with a market share of 16.4% of the global market for automatics. Toyota Motor Corporation and Aisin Seiki are the two major shareholders of Aisin AW, with 51.9% and 42% respectively. Aisin AW, which was set up to be the sole source of RWD automatic transmissions to Toyota, subsequently developed FWD/AWD automatic transmissions. Aisin, as one of the major Toyota group suppliers, shares many designs and development activities with Toyota. See Toyota A transmission for a complete list of Toyota/Aisin models. Aisin AW supplies automatic transmissions to 55 automotive manufacturers around the world, virtually every major OEM. These include General Motors, Ford, Jeep, Mitsubishi, Nissan, Saab, VW, Volvo, Hyundai, MINI among others.
