A power take-off unit (“PTO”) may include a retarder to reduce noise while the transmission PTO output gear is operating at low torque. The retarder may variably load the PTO based on the PTO output load, while disengaging from the PTO while the PTO is not operational. The retarder may also serve as a primary retarder function to slow a vehicle's speed. The retarder may be controlled by a vehicle operator or by a processor.
