Claim 0:
1. A lubricating device for controlling lubrication in a stepped transmission comprising a splitter section with an input shaft and a main gear section with an output shaft and a countershaft;
the splitter section comprising:
a first splitter gear set connectable to the input shaft by a first gear shift mechanism;
a second splitter gear set connectable to the input shaft by the first gear shift mechanism and connectable to the output shaft by a second gear shift mechanism; and

wherein:
a lubrication arrangement for the second splitter gear set is controlled by current positions of the first and the second gear shift mechanisms;
the lubrication arrangement is controlled to at least reduce lubrication when the first and the second gear shift mechanisms are simultaneously connected to the second splitter gear set; and
the lubrication arrangement is deactivated when the first and the second gear shift mechanisms are simultaneously connected to the second splitter gear set.
