Technology and Products Major product information:AT

Direct, smooth, powerful, and quiet acceleration.
Fuel-efficient and eco-friendly.

Striving to actualize such an automobile, Aisin AW made advancements in gear shifting mechanisms from 4-speed to 5-speed, and then 5-speed to 6-speed.
We did not simply make advances in multi-staging. While incorporating the latest control and production technologies, we also completely redesigned internal mechanisms in our products to make them lighter and more compact for installation on a wide range of vehicles.

High Torque Capacity RWD
10-speed AT

AWR10L65

The RWD 10-speed automatic transmission suitable for luxury passenger cars and sports achieved "Rhythmic and smooth shift change" and "Direct" drive feeling by pursuing "Driving pleasure."

Open

"Aiming to create the ultimate AT suitable for luxury cars," we have been engaged in product development in order to achieve the world's highest performance in every aspect, such as fuel economy, acceleration performance and quietness.
We successfully developed the world's first RWD 8-speed AT in 2006, and the world's first* RWD 10-speed AT for passenger vehicles in 2017.
* As of January 2017 according to a survey conducted by Aisin AW

  • ・Rhythmic and smooth shift change is achieved with cross gear steps
  • ・Weight reduction for components, improved hydraulic response, and accuracy achieve excellent responsiveness to the driver's acceleration
  • ・The LOCK-UP range is significantly expanded by developing a high performance small torque converter, and transmission efficiency is increased which resulted in fuel economy improvememt

Applicable Vehicles LS500,LC500(LEXUS)

Pursuing comfortable driving suitable for premium rear-wheel-drive vehicles

Excellent responsiveness to the driver's acceleration is achieved by weight saving for components, improved hydraulic response, and accuracy.

High Torque Capacity FWD
8-speed AT

AWF8G45

Lightweight and compact FWD 8-speed Automatic Transmission delivers both fuel efficiency and improved engine performance.

Open

"We aim to build compact FWD AT suitable for luxury cars that set the standard for the next generation."
In 2012, we developed the world's first FWD 8-speed AT, with a focus on fuel efficiency and acceleration, as well as size reduction to equal 6-speed units.
In 2016, we have developed the latest High Torque Capacity FWD 8-speed AT which has realized even more improvement in fuel efficiency and drivability.

  • ・Achieved significant improvement in fuel economy and drivability by drastic reduction of loss torque and expansion of LOCK-UP range
  • ・Downsized light-weight transmission realized by revising gear train structure, reconsidering material, and optimizing its shape

Applicable Vehicles 
Sienna, Highlander (Toyota)
