Zusammenfassung:	A method for controlling a transmission assembly includes providing a vehicle having a first power source and a second power source disposed in parallel with the first power source. The first power source includes a prime mover and a transmission assembly. The transmission assembly includes a torque converter coupled to the prime mover. The transmission assembly further includes a clutch that selectively engages the torque converter to a transmission of the transmission assembly. The second power source includes a pump-motor unit, a fluid reservoir and an energy storage unit. A torque value of the second power source is compared to a torque threshold value. The clutch of the transmission assembly is disengaged so that the torque converter of the transmission assembly is disengaged from the transmission of the transmission assembly when the torque value of the second power source is greater than or equal to the torque threshold value.
