A powertrain of a vehicle has a drive unit, a transmission and an auxiliary gearbox. Operation of the transmission and the auxiliary gearbox is controlled by a transmission control unit. The transmission control unit controls shifting of the auxiliary gearbox and the transmission while the vehicle is in operation. The auxiliary gearbox may be electronically shifted, independently of activity of the vehicle operator.
