1. A motor vehicle, comprising:
a vehicle body;
a plurality of road wheels attached to the vehicle body;
an engine assembly attached to the vehicle body and configured to generate torque;
a power transmission attached to the vehicle body and drivingly connecting the engine assembly to one or more of the road wheels to thereby propel the motor vehicle; and
a torque converter (TC) assembly attached to the vehicle body and drivingly connecting the engine assembly with the power transmission, the TC assembly comprising:
a TC housing defining therein a fluid chamber and drivingly connected to the engine assembly to receive torque output therefrom;
a TC output member rotatable with respect to the TC housing and drivingly connected to the transmission to transfer torque thereto;
a turbine including a turbine shell, turbine blades mounted to the turbine shell and rotatable within the fluid chamber, and an adapter ring projecting radially outward from the turbine shell, the adapter ring defining a slot;
an impeller including impeller blades juxtaposed with the turbine blades and rotatable within the fluid chamber;
a TC clutch operable to lock the TC housing to the TC output member; and
a torsional vibration damper disposed within the fluid chamber adjacent the turbine and the TC clutch, the torsional vibration damper including:
a sun gear attached to the TC output member to rotate in unison therewith;
a ring gear coaxial with the sun gear and attached to the TC clutch to rotate in unison therewith;
a planet carrier with a pinion gear intermeshed with the ring and sun gears; and
a drive plate attached to the planet carrier and including a tab projecting axially from the drive plate into the slot of the adapter ring to thereby drivingly couple the planet carrier to the turbine blades to rotate in unison therewith.
