Abstract
An automated multi-ratio transmission has a gear-engaging mechanism with a first actuator to move a selector member in a first direction to select a gear ratio, and a second actuator to move the selector member in a second direction to engage the selected gear ratio. The vehicle may be started from stand-still in either a forward or reverse start-up gear ratio, both of which are engaged from an end position of the range of movement of the selector member. In the start-up phase of the vehicle, an automated control means drives the first actuator to the appropriate selector position for either the forward or reverse start-up gear and then drives the second actuator to engage the desired start-up gear.
