Automotive vehicle shift control mechanism for manual transmissions

In a manual multiple-forward-speed vehicle transmission having transmission means shiftable between a reverse drive and a plurality of forward speed ratios, a manual shift lever controlling said transmission means by movement through a shift pattern of selection positions including a neutral position, said shift lever being connected to shift said transmission means to said reverse drive and to one forward speed ratio by movement thereof, respectively, to a pair of selection positions lying at the ends of a substantially linear path extending across said neutral position, and a transmission lever operatively interconnected between said shift lever and said transmission means;

• a misshift preventive mechanism for controlling movement of said shift lever along said linear path between said selection positions for said reverse drive and said one forward speed ratio, said misshift preventive mechanism comprising a projection extending from said transmission lever, a pin located to be engaged by said projection, a housing having said pin mounted therein for movement relative thereto between an extended position and a retracted position, said housing being mounted for movement in directions transversely of the directions of movement of said pin with the path of movement of said housing including an initial position defined therealong, said projection being configured to cause retraction of said pin when said shift lever is within said linear path at said neutral position and to permit movement of said pin to said extended position when said shift lever is moved along said linear path away from said neutral position, said pin being arranged to be engaged by said projection when said pin is in said extended position to cause movement of said housing when said shift lever is moved along said linear path, stopper means for restricting movement of said housing, and spring means biasing said housing for movement to its initial position.
