Aisin AW New Four-Speed Automatic Transmission for FWD Vehicles

Aisin AW has developed a new lightweight, compact automatic transmission: the 60-40LE. The 60-40LE is designed for small cars of up to 1.6L engine displacement. The transmission is an electronically controlled, 4-speed, front wheel drive transaxle utilizing a unique, compact planetary gear train.

This new planetary gear train, combining a dual planetary gearset, establishes the shortest shaft length of its kind. The electronic control system allows for improved shift quality. Application of a linear solenoid allows for optimum control, especially during 2nd to 3rd gear shifting and shifting without the application of a one-way clutch.
