A control system includes a transmission and a controller configured to receive a vehicle stop command; determine a ground speed; compare the ground speed to first and second predetermined speed thresholds; generate, when the ground speed exceeds the second predetermined speed threshold, a downshift command; generate, when the ground speed is greater than the first predetermined speed threshold and less than or equal to the second predetermined speed threshold, a shuttle shift command; determine, when the ground speed is less than or equal to the first predetermined speed threshold, if the transmission is operating in the first or second mode; select, upon determining the operating mode, a four-square clutch; and at least partially engage the selected four-square clutch to slow or stop the work vehicle. 1. A control system for operating a powertrain of a work vehicle having a power source configured to generate power for an output shaft , the control system comprising: at least one forward input clutch configured for engagement when transferring the power in the at least one forward mode,', 'at least one reverse input clutch configured for engagement when transferring the power in the at least one reverse mode,', 'a first output clutch configured for engagement when transferring the power in a first mode of the at least one forward mode or the at least one reverse mode, and', 'a second output clutch configured for engagement when transferring the power in a second mode of the at least one forward mode or the at least one reverse mode; and, 'a transmission positioned operatively between the power source and the output shaft and configured to selectively transfer the power from the power source to drive the output shaft in a first direction according to at least one forward mode and in a second direction according to at least one reverse mode, the transmission including receive or generate a vehicle stop command;', 'determine a ground speed of the work vehicle;', ' ...
