In an automotive manual transmission having a common fork shaft on and along which a plurality for shift forks are slidable and a control rod which is rotatable about and slidable along the axis thereof which is normal to the axis of the common fork shaft, there is provided a shaft control mechanism which converts the axial movement of the control rod to a sliding movement of selected one of the shift forks along the axis of the common fork shaft. The shift control mechanism comprises a supporting member removably connected to the transmission housing, a pivoting pin supported by the supporting member and having an axis which is normal to both the axes of the common fork shaft and the control rod, a plurality of pivoting levers pivotally mounted by the pivoting pin so as to be pivotable about the axis of the pivoting pin, one end of each pivotting lever being pivotally jointed with an extension of the corresponding one of the shift forks to cause movement of the corresponding shift fork on and along the common fork shaft upon pivoting movement of the pivotting lever, and a head member secured to the control rod, the head member being brought into engagement with the other end of each pivoting lever upon rotational movement of the control rod about its axis into a given position.
