JATCO Developes 7-speed Automatic Transmission for RWD vehicles
JATCO Ltd (president: Shigeo Ishida, headquarters: Fuji City, Shizuoka Prefecture, capitalization: \29,935.3 million), Automatic Transmissions and Continuously Variable Transmissions (AT/CVT) manufacturer, announces that it has developed a new 7-speed automatic transmission (AT) for rear-wheel drive (RWD) vehicles.
The new AT, comprising two types with medium and large torque capacities, can be used for a variety of models, and hence can serve a greater number of users than a conventional type. Costs of producing the AT have been reduced because it shares parts and production equipment with conventional 5-speed ATs.
The new AT features close gear ratios and expanding the ratio coverage, which make for dynamic startup and acceleration in low to medium speed ranges, as well as an improved fuel economy and quieter driving at high speeds.
Other features of the AT include more advanced adaptive shift control (*1) and synchronized revolution control (*2), which contribute to improved maneuverability by responding to driver intentions more faithfully. These features will surely make driving more exciting and pleasant.
The new 7-speed AT has been produced in the Fujinomiya area (Fujinomiya City, Shizuoka Prefecture) in February, and will be supplied to Nissan Motor from March 2008.
