Abstract
A control system operates a power train of a work vehicle. The system includes a transmission arrangement which transfers power from an engine to an output shaft of the vehicle to drive the vehicle in a first or second direction according to at least one forward or reverse modes. The arrangement includes a forward directional clutch and a reverse directional clutch, and a controller. The controller is configured to determine if one of the clutches is engaged; evaluate a speed of the engine; and provide a torque command to engage the other of the clutches to slow the speed of the engine when a shuttle shift is initiated, or when the speed of the engine exceeds a predetermined speed threshold.
