Claim 0:
1. An automatic transmission, comprising:
a plurality of rotary shafts including an output shaft that outputs a drive force;
a plurality of gears including an output-side gear provided on the output shaft;
a plurality of synchromesh mechanisms including an output-side synchromesh mechanism that couples between the output shaft and the output-side gear;
a shift position detection section that detects which of a plurality of shift positions including a neutral position and a parking position is selected; and
a control section that actuates at least one of the plurality of synchromesh mechanisms other than the output-side synchromesh mechanism and causes the at least one of the plurality of synchromesh mechanisms to couple between at least one of the plurality of rotary shafts other than the output shaft and at least one of the plurality of gears other than the output-side gear, in a case where the neutral position or the parking position is detected by the shift position detection section, wherein:
the plurality of rotary shafts includes a first input shaft including a first clutch capable of disconnecting the drive force and a second input shaft including a second clutch capable of disconnecting the drive force, the second input shaft being provided coaxially with the first input shaft, and
the control section actuates, among the plurality of synchromesh mechanisms, a synchromesh mechanism in which the drive force is not transmitted to the output shaft even when either of the first clutch or the second clutch is connected, in a case where the neutral position or the parking position is detected by the shift position detection section.
