Method for operating a transmission device, and corresponding transmission device

A transmission device, comprising:

• one or more memory devices;
• one or more timers;
• and
• a control device communicatively coupled to the one or more memory devices and the one or more timers;
• at least one oil chamber, in which is arranged a wheelset of the transmission device, said oil chamber connected to a pump configured to supply oil to the oil chamber based on a determined temperature in the at least one oil chamber, wherein the transmission device is designed to determine the temperature in the at least one oil chamber so as to determine an overall energy level for the at least one oil chamber based on the determined temperature, wherein, in order to determine the temperature in the at least one oil chamber, an initial value is determined for the overall energy level at the start of the operation of the transmission device with the determination of a standardized shutdown time, by the control device, as a function of an external temperature and of the overall energy level that is present at the shutdown preceding the start of the operation of the transmission device, wherein the standardized shutdown time is the span of time after the shutdown at the end of which the temperature in the at least one oil chamber has adjusted to the external temperature,
• determination of a corrected shutdown time, by the control device, as a function of the standardized shutdown time and of a measured shutdown time, and
• determination of an initial value, by the control device, as a function of the corrected shutdown time and of the momentary external temperature.
