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.
