In accordance with an example embodiment, a transmission may include a first mode in which a low range clutch is engaged and a first synchronizer is in a first engaged condition causing an output shaft to rotate relative to a first range shaft based upon a ratio of a first range gear to a second range gear. The transmission may include a second mode in which a high range clutch is engaged and a second synchronizer is in a first engaged condition causing the output shaft to rotate relative to a second range shaft based upon a ratio of the first range gear to the second range gear. A shift from the first mode to the second mode includes engaging the second synchronizer in the first engaged condition before disengaging the low range clutch and engaging the high range clutch.
