Abstract: The invention relates to a method for changing gear stages in a transmission having a hydrostatic transmission and a downstream manual transmission, and a corresponding transmission arrangement. First, a desire to shift is detected within the manual transmission to change the gear stages. The hydrostatic transmission and the downstream manual transmission are activated to change the gear stage of the downstream transmission. Whether the gear stage to be engaged through a gear stage change was successfully engaged is detected by a detection device, which is connected to an electronic control unit of the transmission arrangement. If the engagement of the gear stage to be engaged is not successful, the original gear stage is reengaged. After the engagement of the original gear stage, the downstream transmission is again activated such that the gear stage to be engaged is engaged.

Abstract: The invention concerns a method and a transmission arrangement for changing gears in a transmission with a hydrostatic transmission and a manual gearbox (4) connected downstream from it. First the output torque of a hydrostatic motor (9) is reduced. After the reduction of the output torque of the hydrostatic motor (9), an engaged gear (12, 13) of the manual gearbox (4) which is connected downstream is disengaged. An output rotational speed of the hydrostatic motor (9) corresponding to the gear (13, 12) to be engaged is determined. The gear ratio of the hydrostatic transmission is then adjusted, so that the output rotational speed of the hydrostatic motor (9) is higher than the determined corresponding output rotational speed. After this increased output rotational speed is reached, the gear (13, 12) to be engaged is engaged.
