A hydraulic control device is disposed forward of a case housing a speed change mechanism in an on-vehicle state. A detent lever is fixed to the control shaft, has a first end connected to a parking rod, and includes a detent recess with which a detent mechanism is engaged. A swing lever includes a shaft serving as a swing center, a first extension extending from one end of the shaft, and a second extension extending from the other end of the shaft. The first extension is connected to a second end of the detent lever. The second extension is connected to a manual valve. An axial position of the manual valve changes in accordance with a rotation angle of the control shaft.
