Transmission shifter assembly with automatic position reset

At least some implementations of a transmission gear shifter include a first body rotatable among multiple positions, a second body rotatable among multiple positions, a retainer and first and secondactuators. The retainer is movable relative to the second body between a first position in which the retainer prevents rotation of the second body, and a second position in which the retainer permitsrotation of the second body. The first actuator is coupled to the retainer to move the retainer between the first and second positions. The second actuator provides a force on the second body to rotate the second body when the retainer is in the second position. 变速器换档器的至少一些实施方式包括可在多个位置之间旋转的第一主体、可在多个位置之间旋转的第二主体、保持器以及第一致动器和第二致动器。所述保持器可相对于第二主体在保持器防止第二主体旋转的第一位置和保持器允许第二主体旋转的第二位置之间移动。所述第一致动器耦合到所述保持器，以在第一位置和第二位置之间移动所述保持器。当保持器处于第二位置时，所述第二致动器在第二主体上提供作用力，以旋转第二主体。
