<p>An automatic dual-clutch transmission (1, 100) is able to establish a parking lock by bringing one of a first input shaft (15; 115) and a second input shaft (16; 116) into engagements with a low speed stage gear train (21 a, 21 b; 122a, 122b) as well as with a reverse stage gear train (27a-27d; 122a, 122b, 128a, 128b) in performing a parking. Gears of an engaging member (S1, SR; S2, SR) and a mating sleeve (M) in at least one of a low speed stage shift clutch (30A, S1; 130B, S2) and a reverse stage shift clutch (30C, SR; 130D, SR) which are simultaneously brought into engagements to establish the parking lock are able to mesh with each other at axially extending side surfaces (S1b, Mb) thereof which are formed to extend linearly in parallel to an axial direction thereof.</p> |
