A combined locking system which comprises a lever and a body and which is configured to block a movement of the lever in different gear positions with respect to the combined locking system's body in automatic transmission systems comprising: • at least one first locking element which is arranged on said lever and which is movable bi-directionally along the axis (x) of the lever, • at least one cover which is connected to said body as a complementary element and which includes the locking shapes thereon, ∘ wherein the locking shapes are arranged with respect to the lever axis (x) and disposed in downward direction on the cover, and enables the immobilization of the lever in the respective gear position with the at least one first locking element engaged therein, • at least one pin which is arranged on said first locking element, • at least one channel which directs the lever by guiding it on said pin, • multiple recesses which are arranged on said channel and which enable the immobilization of the lever in the respective gear positions, • at least one index part which incorporates said channel and recesses thereon and which is movable with respect to the lever axis (x) in a vertical direction, • at least one second locking element which is disposed at a position under the index part with respect to said lever axis (x) and which blocks the movement of the index part in the vertical direction, • at least one locking index part which is arranged on the body and which enables a movement of the at least one second locking element in a lateral direction (y) by guiding it, • at least one driving element driving the movement of the second locking element in the lateral direction represented by a lateral axis (y), • at least one control unit which is configured to control the function of driving the movement of the second locking element in the lateral direction or axis (y) of said at least one driving element. • at least one first locking element which is arranged on said lever and which is movable bi-directionally along the axis (x) of the lever, • at least one cover which is connected to said body as a complementary element and which includes the locking shapes thereon, ∘ wherein the locking shapes are arranged with respect to the lever axis (x) and disposed in downward direction on the cover, and enables the immobilization of the lever in the respective gear position with the at least one first locking element engaged therein, • at least one pin which is arranged on said first locking element, • at least one channel which directs the lever by guiding it on said pin, • multiple recesses which are arranged on said channel and which enable the immobilization of the lever in the respective gear positions, • at least one index part which incorporates said channel and recesses thereon and which is movable with respect to the lever axis (x) in a vertical direction, • at least one second locking element which is disposed at a position under the index part with respect to said lever axis (x) and which blocks the movement of the index part in the vertical direction, • at least one locking index part which is arranged on the body and which enables a movement of the at least one second locking element in a lateral direction (y) by guiding it, • at least one driving element driving the movement of the second locking element in the lateral direction represented by a lateral axis (y), • at least one control unit which is configured to control the function of driving the movement of the second locking element in the lateral direction or axis (y) of said at least one driving element.
