  • Patent number: 5321993
    Abstract: A manual transmission shift control apparatus wherein dual cables lead from a floor-mounted shift control lever assembly directly, i.e., without bending, to dual select and shift shafts operatively connected to the transmission. The dual shafts are rotatably mounted and operated in a housing on top of the transmission. A selector mechanism bearing a shift finger is rotatably and slidably mounted on a shaft in the housing, such that, through suitable linkage, the shift finger is selectively rotated by the rotated select shaft into 1/2, 3/4, or 5/R shift positions, and then slid by the rotated shift shaft into the 1, 3 or 5 shift ratios in one direction, or the 2, 4 or R shift ratios in the other direction.
    Type: Grant

  • Patent number: 5144854
    Abstract: In a shift control arrangement for a manual transmission wherein dual cables lead from a floor-mounted shift control lever to dual select and shift shafts operatively connected to the transmission, a shift mechanism bearing a shift finger is rotatably and slidably mounted on a shaft in the housing, such that, through suitable linkage, the shift finger is selectively rotated by the select shaft into 1/2, 3/4, or 5/R shift positions, and then slid by the shift shaft into the 1, 3 or 5 shift ratios in one direction, or the 2, 4 or R shift ratios in the other direction. A reverse inhibitor mechanism operates in conjunction with a pin extending from the rotatable and slidable shift mechanism to prevent an inadvertent manual shift from 5 to R ratio positon, and to result in a shift from 5 to 4 instead.
