AN ELECTRONIC CONTROLLED FULL AUTOMATIC TRANSMISSION has been developed. Automatically controlled dry clutch and synchromeshed gear transmission make driving easier, maintaining better fuel efficiency of a mechanical transmission. The electronic control, similar to use of manual transmission, and H-pattern floor shift type “selector lever,” only for electric input device, make it possible for the driver to choose either of two types of driving - “sporty driving” of a manual transmission and “easy driving” of an automatic transmission. In the automatic mode, the microprocessor makes it possible to have stop-and-go operation that is so troublesome with a dry clutch. Adoption of a new brake system improves safety on ascending grade starts without torque converters.
