A method for preventing shift hunting in a powertrain including an engine and a transmission having a variator, a first gearset, and a second gearset is disclosed. The method includes operating the engine at a first substantially constant speed, detecting a shift condition, and operating the engine at a second substantially constant speed as a function of detecting the shift condition. The second speed is different than the first speed.
