Automatic transmission system for vehicles

摘要

In a vehicle automatic transmission system employing a gear-type transmission, the system has a selector having a drive position for allowing automatic gear-change operation over a plurality of gear positions and a gear-holding position provided adjacent to the drive position, and the gear-change operation is limited below a gear position or is fixed at the gear position which is decided the actual gear position at the time a operation lever of the selector is moved from the drive position and the gear-holding position, whereby the system enables gear holding in each of the gear position by only providing the selector one with additional position.
