A powertrain braking system for a vehicle includes an powerplant that can be regulated to provide a desired powerplant torque and a transmission that transfers the desired powerplant torque at one of a plurality of gear ratios to provide a desired axle torque. A control module calculates an axle torque command based on a powertrain braking request and determines a shift command based on the powertrain braking request. The control module controls the powerplant based on the axle torque command and the transmission based on the shift command to achieve a desired vehicle deceleration rate that corresponds with the powertrain braking request.
