Abstract
A torque-transmitting system for vehicles has a main drive clutch operable by means of a clutch-actuator, a transmission, a shift mechanism for setting the transmission ratio, a selector lever allowing the driver to select between a neutral mode or a drive mode of the transmission, and electronic control means for controlling the clutch actuator and the shift. mechanism. The electronic control means will cause the clutch-actuator to disengage the clutch when the engine is started and to re-engage the clutch if the transmission has been left in neutral mode for a preprogrammed time period while the vehicle is standing still, so as to turn the input shaft of the transmission and thereby warm up the transmission oil.
