ABSTRACT:
A fluid level of hydraulic fluid circulated in an automatic transmission is regulated while an internal combustion engine is running. When the fluid level is regulated, the hydraulic fluid is cooled, for example, by coolant passing through a radiator. In the cooling of the hydraulic fluid, the degree of cooling of the hydraulic fluid is controlled such that the temperature of the hydraulic fluid falls within an acceptable range. This prevents inaccurate fluid level regulation due to thermal expansion of the hydraulic fluid.
