A vehicle includes an engine, a transmission having a friction clutch and a binary clutch assembly, and a controller. The controller executes a method to detect the requested shift of the transmission to neutral, and when a set of conditions are satisfied during the requested shift, to automatically decrease a pressure command to the friction clutch such that torque capacity of the friction clutch decreases from a full torque capacity and begins to slip. The controller holds the binary clutch assembly at a calibrated pressure while the friction clutch slips, disengages the binary clutch assembly only when the binary clutch assembly is released and not loaded, and increases the pressure command to the friction clutch to restore full torque capacity to the friction clutch and complete the requested shift to neutral.
