1. A method for operation of an electric driveline system, comprising:
mechanically coupling a power take-off (PTO) to a first electric machine via engagement of a first synchronizer coupled to a PTO input shaft while a second electric machine transfers mechanical power to a transmission; and
mechanically coupling the first electric machine to the transmission via operation of a second synchronizer and a first friction clutch that are coupled to a gear on an output shaft of the first electric machine;
wherein the second electric machine is mechanically coupled to a gear in the transmission; and
wherein the first electric machine is selectively mechanically coupled to the gear in the transmission gearset.
