Abstract

A transmission ratio selector mechanism having an upper manually operable gear lever (120) which is mounted (139, 250) intermediate its ends for pivoting about two perpendicular axes and a lower lever member (134) which is pivoted in a fixed mount (136) at its lower end (135) and is connected at its upper end (137) with the lower end (138) of the gear lever (120). The lower lever (134) is interconnected (133) intermediate its ends with a ratio selector shaft (112) whose longitudinal axis passes through the fixed mount (136). Pivoting of the gear lever (120) about one of the perpendicular axis causes axial displacement (W1, W2) of the selector shaft (112) in a direction parallel to its longitudinal axis and pivoting of the gear lever about the other perpendicular axis causes turning of the selector shaft about its longitudinal axis to move one or more ratio selector forks (101, 102). The gear lever (120) also has a range change position (H/L) which can only be reached when the associated transmission is in a neutral condition. The mounting (400) of the upper lever (120) may also vibrationally isolate the upper lever relative to the lowr lever (134).
