Abstract

A system for bypassing a torque converter in a powertrain is provided. The system includes a torque generating device including an output shaft and a transmission assembly. The transmission assembly includes a transmission output shaft and a torque converter, a torque converter bypass shaft. The transmission assembly further includes a disconnect clutch selectively coupling the torque converter with the torque generating device and a torque converter clutch selectively coupling the torque converter bypass shaft with the torque generating device. Engaging the disconnect clutch and disengaging the torque converter clutch enables the torque generating device to transmit torque to the transmission output shaft through the torque converter. Engaging the torque converter clutch and disengaging the disconnect clutch enables the torque generating device to transmit torque to the transmission output shaft through the torque converter bypass shaft.
