The invention discloses a special hybrid transmission lubricating pipeline and a working method thereof, and belongs to the technical field of transmissions. The oil outlet ends of the first oil way and the second oil way are communicated with the oil inlet ends of the long planetary gear shaft oil way and the short planetary gear shaft oil way, and bearing oil supply holes are formed in the middle of the long planetary gear shaft oil way and the middle of the short planetary gear shaft oil way. The method comprises the following steps that lubricating oil is supplied to the long planetary gear needle bearing and the short planetary gear needle bearing through the first oil way; lubricating oil is supplied to the long planetary gear needle bearing and the short planetary gear needle bearing through a second oil way. The planetary structure adopts a Ravigneaux type planetary structure, more gears are provided, meanwhile, the structure is more compact, and the problem that the fuel saving rate is reduced under
