Patent ID: 7114410

Claim:
A select system for an automatic transmission having a select lever switching over between a mechanical automatic mode and an electrical manual mode, comprising: a single engaging protrusion provided to said select lever and extended for a predetermined distance to one side, said engaging protrusion comprising an upper protrusion and a lower protrusion; and a rotatable linkage member having an engaging groove for inserting said engaging protrusion therein, wherein when said select lever is in the automatic mode, said linkage member is rotatable with a shifting movement of said select lever by an engagement between said engaging protrusion and a part of said engaging groove so as to achieve mechanical transmission control of said automatic transmission, and when said select lever is in the manual mode, said lower protrusion disengages from the part of said engaging groove and said upper protrusion restricts movement of said linkage member relative to said engaging protrusion within a predetermined distance smaller than a moving stroke of said linkage member necessary to achieve the mechanical transmission control of said automatic transmission, wherein said engaging groove has a substantially convex shape in a side view of said automatic transmission protruded upwardly, said engaging groove comprising: a hollow upper groove corresponding to said upper protrusion having an open bottom; and a hollow lower groove corresponding to said lower protrusion continuous with the upper groove, wherein said upper protrusion fits in said upper groove when said select lever is in the automatic mode.
