Abstract

A motor vehicle has at least one ground running wheel driven by an internal combustion engine (10) via a transmission comprising a clutch (14) and a change-speed gearbox (12). Gearbox (12) has a plurality of mutually exclusively engageable gear ratios any desired one of which can be engaged by pivoting gear lever (16) manually, in direction (A) or (B) accordingly, about pivot (34) so that part of the gear lever (16) above the pivot (34) moves from one side of the gear shift pattern to the other side. Gear lever (16) comprises shaft (32) pivoted at (34) and a hand knob (42) on a tube (40) rockably pivoted at (44) on the shaft (32). When the tube (40) is rocked by manual force in direction (a) or (b) relatively to shaft (32) a signal is sent on line (64) or (66) to clutch control (18, 20) causing automatic dis-engagement of the clutch (14). Continued application of the manual force on the tube (40) causes the latter to push the shaft (32) which pivots in direction (A) or (B) to the opposite side of the gear shift pattern. On control (18, 20) receiving a signal on line (54) that a new gear ratio has been engaged, the control (18, 20) automatically re-engages the clutch (14). Springs (46) act to hold the tube (40) in a central or initial position relative to shaft (32) when no manual force is applied to knob (42). The clutch control (18, 20) includes an initiating device (68) which observes when the new gear ratio has been engaged and prevents a subsequent dis-engagement of the clutch (14) until the tube (40) has first been allowed to return to the initial position relative to the shaft (32).
