Abstract
A lubricating oil supply apparatus for a hydraulically operated vehicular transmission has a lubricating oil passage for supplying oil discharged from a discharge port of a pressure control valve which is provided in a hydraulic control circuit of the transmission to lubricating portions thereof as lubricating oil. The lubricating portions are divided into a plurality of groups depending on a change in a required amount of lubricating oil due to a temperature of the transmission. The lubricating oil passage is branched into a plurality of branches corresponding to the groups. The lubricating oil supply apparatus has a choke type of throttle which is disposed in at least one of the branches of the lubricating oil passage.
