A hybrid vehicle has an engine, an electric machine connected to the engine by an upstream clutch, a transmission gearbox connected to the electric machine by a downstream clutch, and a controller. The controller is configured to, in response to a commanded upshift of the gearbox, modulate a pressure of the upstream clutch. A method for controlling a vehicle includes, in response to a commanded upshift of a gearbox, controlling an upstream clutch to a first nonzero speed differential corresponding to a first inertia connected to and upstream of the gearbox to reduce inertia torque during the upshift. A method for controlling a vehicle includes, in response to a commanded upshift of a gearbox when the vehicle is beyond an electrical limit and a fast path torque reduction limit, slipping an upstream clutch and reducing torque outputs of an engine and an electric machine.
