ABSTRACT

A lubrication control apparatus for an automatic transmission includes a first
lubrication circuit that supplies lubricating oil to a starting frictional
engagement element to be engaged when a vehicle starts, a second lubrication
circuit that supplies the lubricating oil to a lubricated portion other than
the starting frictional engagement element, and a controller that performs
control to increase a flow rate in the first lubrication circuit while
limiting a flow rate in the second lubrication circuit when a temperature of
the starting frictional engagement element is equal to or higher than a
threshold temperature, and the controller changes the threshold temperature in
accordance with the temperature of the lubricating oil.
