Abstract: An automatic transmission includes a gear lever mounted at the interior of a vehicle, a manual control lever connected to the gear lever via a gear cable, a position detecting unit for detecting the position of the manual control lever when a gear-shifting operation is performed, and a position fixing unit disposed between the manual control lever and the position detecting unit for fixing the manual control lever at an assembly reference position. The manual control lever is fixed at the assembly reference position by the position fixing unit. As a result, the manual control lever is not directly fixed to the position detecting unit, and therefore, there is no necessity for moving the position detecting unit. Consequently, interference between the manual control lever and other components is prevented, and the manual control lever is easily assembled.
