Abstract

A vehicle transmission arrangement comprising a multi-ratio gearbox (10) is provided. The gearbox drives one or more wheels of the vehicle from an associated engine (12) via a drive disconnection means. A control system (110) is arranged to ensure that, when the vehicle comes to rest (a) the drive disconnect means is set to a condition in which no power is transmitted from the engine to the gearbox, and (b) more than one gear ratio is engaged in the gearbox to lock up the gearbox and hence hold said one or more wheels against rotation thus holding the vehicle at rest.
