Abstract: An electric vehicle transmission, the transmission comprising an input shaft arranged to be driven by an electric motor, an output shaft arranged to transfer drive from the input shaft to driving wheels of the vehicle to which the transmission is fitted, a first clutch for engaging/disengaging a first gear ratio of the transmission, a second clutch for engaging/disengaging a second gear ratio of the transmission, and a fluid pump driven in response to rotation of the output shaft, wherein the first clutch is biased to engage said first gear ratio in the absence of pressure from the fluid pump.

Abstract: A multi-ratio automatic transmission for a vehicle, the transmission having a single planetary gear set, a plurality of friction elements for coupling components of the planetary gear set between an input and an output of the transmission in different configurations so as to achieve a plurality of forward drive ratios, and a control system for selectively engaging/disengaging the friction elements in different combinations to effect selection of the ratios, wherein the friction elements include first and second clutches mounted forward of the planetary gear set, and wherein power flow in each of the forward drive ratios is routed from the input to the planetary gear set through at least one of the first and second clutches.

Abstract: An automotive transmission having a hill hold feature, comprising an input shaft arranged to be driven by an engine, an output shaft arranged to transfer drive from the input shaft to driving wheels of a vehicle to which the transmission is fitted, and a transmission housing within which the input and output shafts rotate, wherein a one-way clutch is coupled to the input shaft and the housing to allow rotation of the input shaft in only one direction relative to the housing, such that when a forward gear of the transmission is engaged the vehicle is prevented from rolling backward.
