AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2007/063639

A1
Abstract:
An automatic transmission in which a shock is prevented from occurring when a brake is engaged by operating the brake to stop the rotation of a clutch due to a drag torque in a non-drive range such as neutral range. The automatic transmission can be shifted in a plurality of stages by engagement and disengagement of plural frictional engagement elements formed of at least a first clutch and a first brake and can be changed between a drive range and the non-drive range by the operation of a shift lever. The first brake is engaged in the non-drive range to secure an intermediate rotating member to a transmission case.
