Abstract
An automatic transmission is capable of shifting between multiple speeds by engaging and disengaging multiple frictional engagement devices including at least one clutch and one brake, and is capable of switching between a driving range and a non-driving range with operation of a shift lever, wherein a first brake is engaged to fix an intermediate rotary member to a transmission case in a non-driving range such as neutral range. Thus, rotation of a clutch from drag torque can be stopped and shock due to engagement of a brake can be prevented by engagement of the first brake in the non-driving range.
