A gear carrier drives a propulsor. Two ring gears engage with respective tooth locations on planet gears. A first gear tooth set on a ring lock selectively engage with a first ring gear and a second gear tooth set on a ring lock selectively engage with a second ring gear. When the first gear tooth set on the ring lock engages the first ring gear, rotation of the first ring gear stops, and the planet gears drive the carrier at a first speed. When the second ring lock gear tooth set engages the second ring gear, rotation of the second ring gear stops and the planet gear drives the carrier at a second speed which is different than the first speed. An aircraft and a method are also disclosed.
