Technology and Products AW's Automatic Transmission

Using the latest cutting-edge technology to support enhanced safety, security, and comfort of the car society

Aisin AW was established in 1969 as a joint venture between Aisin Seiki Co., Ltd. and BorgWarner Inc. of the U.S. At that time manual transmission (MT) vehicles were the standard, but Aisin AW had a grand dream of "contributing to the car society through the development of automatic transmissions (ATs)".

At a time when only a small percentage of automobiles in Japan were fitted with automatic transmissions and despite encountering many trials, such as the "dollar shock" and the two oil crises, Aisin AW pressed forward with strong intent and passion to develop new products, and thus, in 1972 launched production of a newly developed RWD 3-speed automatic transmission (AT). Then, in 1977, we developed the world's first 4-speed AT with RWD overdrive. Subsequently, with our eyes on arrival of the AT age, Aisin AW produced a series of world-first products.

The newly-developed RWD 3-speed AT was installed on the Corona Mark II

Product development applying cutting-edge technology

ATs are essential for automobiles. Aisin AW developed and commercialized new AT one after another to meet the demands of the changing times from 4-speed, to 5-speed, and 6-speed ATs, up to the continuously variable transmissions (CVTs) of today.
As an automobile parts manufacturer, we developed the first environmentally-friendly hybrid system in 2004 and in 2006, we succeeded in commercializing the world's first RWD 8-speed AT. We then successfully commercialized a FWD 8-speed AT in 2012 and a RWD 10-speed AT in 2017.
