ABSTRACT:
A centering spring apparatus in a shift control mechanism includes a plurality of brackets providing stationary ground members for spring members and a shift control lever, which is operable to pick up the springs from the grounded portion to impose a centering force on the shift lever. These springs are disposed such that three different centering forces can be occasioned upon the shifting of the lever from one neutral position toward other neutral positions.
