ABSTRACT:
A stator torque transmitting assembly for a vehicle including a stator shaft connected to a stator in a torque converter for the vehicle and arranged to transmit torque from the stator during a torque conversion mode for the torque converter. In some aspects, the assembly includes a first planetary gear set with a first sun gear, a first planetary carrier, and a first ring gear. The first sun gear is rotationally connected to the stator shaft and the first carrier is grounded. A first transmission input shaft is rotationally connected to the first ring gear and to a second carrier in a second planetary gear set in a transmission in the vehicle. A second transmission input shaft, rotationally connected to a turbine in the torque converter, is rotationally connected to a second ring gear in the second planetary gear set.
