In order to implement a reliable supply of lubricant to gear unit components during emergency or spinning operation of a gear unit, level control is provided in a lubricant sump of the gear unit as a function of the operating state by means of a control unit associated with a lubricant pump. During normal operation the level is adjusted to dry sump level. In contrast, the lubricant pump is switched off in emergency or spinning operation, so that a splash lubrication level is automatically achieved in the lubricant sump.

An oil temperature sensor is externally mounted on a side plate of an oil pan cover that constitutes an external cover for an oil pan apparatus. The oil temperature sensor can output a signal in accordance with the oil temperature prevailing near a thermostat valve apparatus in a second chamber. If the second chamber oil temperature rises immediately after startup of an engine, a CPU judges that an open valve failure has occurred, that is, the thermostat valve apparatus is stuck open. If the oil temperature of the second chamber is not raised when an adequate amount of time has elapsed after the end of a warm-up operation, the CPU judges that a closed valve failure has occurred, that is, the thermostat valve apparatus is stuck closed.
