Abstract: A vehicle includes a transmission and a controller. The transmission has clutches and multiple speed ratios that are established during gear upshifts upon torque being transferred from off-going to oncoming clutches. The controller is programmed to, in response to a difference between actual and target times of a desired flare at a transmission input exceeding a threshold during an upshift, adjust the torque of the off-going clutch during a torque transfer phase of a subsequent upshift based on the difference.
