Abstract
A method of changing from a first gear position to a second gear position of a transmission arrangement is disclosed. The arrangement includes a rotatable transmission member, a hydrostatic continuously variable transmission coupled to the transmission member and operable to rotate the transmission member at a first speed, a controller configured to control operation of the hydrostatic continuously variable transmission, and a gear apparatus coupled to the transmission member and configured to be shiftable between at least the first gear position and the second gear position. The method includes controlling the hydrostatic continuously variable transmission, using the controller, to rotate the transmission member at the first speed, and shifting the gear apparatus from the first gear position to the second gear position while the transmission member is rotating at, or converging with, the first speed.
