Abstract
A method of controlling a machine transmission includes determining a first target torque of the transmission. The first target torque includes a combination of a torque limit associated with a power source of the machine and a virtual retarding torque. The method also includes directing the transmission to generate a first output corresponding to the first target torque. The first output of the transmission increases a speed of the power source from a first power source speed to a second power source speed and decreases a travel speed of the machine from a first travel speed to a second travel speed. The method further includes determining that the first target torque is not equal to the torque limit, and determining a second target torque of the transmission in response. The second target torque is less than the first target torque.
