A position sensor assembly for detecting linear movement of a transmission manual valve is comprised of a set of permanent magnets mounted on a movable carrier and an array of GMR elements located between the juxtaposed magnet poles. The magnet set establishes a high and low magnetic flux field pattern across the GMR elements whose resistance values decrease as they are subjected to the moving magnetic field. The change in resistance is converted to a linear position output signal corresponding to the displacement of the transmission manual valve. The magnet set is moved transversely to the direction of movement of the manual valve. The magnet set is assembled on a magnet carrier that is mechanically linked to the transmission manual valve for which linear position signal is desired.
