ABSTRACT:
An automatic transmission for outputting shifting commands by manual operation of a manual shift lever in addition to an automatic shifting. When a first-stage shifting command is output, a clutch timer is set. When a second-stage shifting command is output during counting by the clutch timer, the second-stage shifting is prohibited. A shifting command storage timer is set simultaneously with the prohibition of the second-stage shifting. If the time is counted up by the clutch timer during counting by the shifting command storage timer, the second-stage shifting is permitted at this time point. If the time is counted up by the shifting command storage timer earlier than by the clutch timer, the second-stage shifting command is canceled. Thus, the first- and second-stage shifting operations are prevented from being continuously conducted, thereby suppressing the time lag required for the engagement of the hydraulic engagement element to the minimum.
