Abstract
JATCO developed an all new 7-speed automatic transmission (AT) for front engine rear wheel drive medium and large vehicles. This transmission features high torque capacity, downsizing, and innovative technology to realize fuel economy improvement. In addition, it offers excellent driveability and shift responsiveness for maximum driver satisfaction and pleasibility. Specifically, the new lock-up system and adaptive shift controls add value in terms of “Joy of Driving” while providing a 7% improvement in fuel economy over the 5 speed AT it replaces.
