A control device (16) for a gear change (2) of a motor vehicle has a control spindle (110), which extends along an axis thereof (111), is provided with at least one radial control finger (117), and is movable with respect to a fixed supporting structure (20) with an axial translational motion and with a rotary motion to select the ranges of the gears, and, for each range, to engage at least one gear starting from an idle condition; the spindle (110) is carried into a pre-defined axial reference position and into a pre-defined angular reference position by two substantially spherical bodies (123), which are carried by the fixed supporting structure (20), and act on centring profiles (156, 157) shaped in such a way as to define the two reference positions; said centring profiles are provided on one and the same positioning body (122) coupled in a fixed position with respect to the control spindle (110).
