ABSTRACT:
A drop-in type shifter is provided for an automotive transmission, the shifter employing one or more washer-like flat springs for spring biasing a shift stick to a predetermined position on the shifter and actuatable for changing the drive ratio of the transmission when the shift stick is pivoted. A base is adapted for mounting the shifter on the transmission. A spherical socket is disposed on the base, and a spherical ball is disposed on the shift stick, the shift stick being received in the ball for pivotally mounting the shift stick on the base. One or more flat washer-like springs are provided having an aperture through which the upper end of the shift stick extends, the washer-like spring being normally planar in an unstressed condition but being compressible into a curvilinear predetermined cross-sectional shape as installed. A rocking shaft on the shift stick includes opposing ends engaging the washer-like springs to resiliently flex the washer-like springs into an increasing curvilinear cross-sectional shape as the shift stick is moved away from a predetermined neutral position so as to spring bias the shift stick to return to the predetermined position.
