The ECPC transmission is controlled by the Chassis ECM.Power flows from the engine and through the torque converter and the transmission. The power then goes through the drive shaft and to the differential. The rear axles mechanically connect the differential to the final drives. The final drives are connected to the rear wheels. Power is then sent to the tires.
