Technology and Products AW’s Automatic Transmissions

Our latest cutting-edge technology supports enhanced safety, security, and comfort in mobility society.

Aisin AW was established in 1969 as a joint venture between Aisin Seiki Co., Ltd. and BorgWarner Inc. of the United States. At that time, manual transmission (MT) vehicles were the standard; however, Aisin AW had a grand dream of “contributing to mobility society through the development of automatic transmissions (ATs).”

At the time, ATs represented low percentage of transmissions installed in vehicles in Japan. Driven by our strong vision and passion for ATs, we pursued product development despite the numerous hardships including the dollar and oil shocks, and commenced the production of new RWD 3-speed AT in 1972. Furthermore, we developed the world’s first RWD 4-speed AT with overdrive in 1977, and thereafter continued to release a succession of world first products in anticipation of the age of the AT.

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

Product Development with Cutting-Edge Technology

ATs are essential for automobiles. Aisin AW developed and commercialized new ATs one after another to meet the demands of the changing times with 4, 5, and 6-speed ATs and the continuously variable transmissions (CVTs) of today.
As an auto 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.
