Abstract
A gear selector means for use with a transmission having a main change speed gear set (X) and one or more associated range change gear sets (Y, Z). The selector means includes a selector member (50) which is movable to a number of positions (1, 2, 3, 4) for the selection of a number of change speed ratios of the transmission and which has a neutral position or series of positions (n) corresponding to a neutral condition of the transmission. The selector member is movable from the or a neutral position (n) to an 'up' position (52) in which upward range changes can be made in a predetermined sequence (A, B, C, D) and to a 'down' position (53) in which downward range changes can be made in a predetermined sequence, each movement of the selector member to the 'up' or 'down' position being arranged to change the operative range of the transmission either up or down to the next range in the predetermined sequence.
