Abstract
A fluid level control valve has a base with a precisely controlled aperture formed therein which mounts on a transmission oil reservoir. A cover is pivotably disposed over the aperture and is biased by a thermostatic element in a direction tending to close the aperture. The thermostatic element is an elongated flat strip having each end captured by a bracket formed in each end of the base. A calibration post is precisely positioned on the cover to work with the brackets to place the thermostatic element in the desired position to provide a preselected force on the cover. The base has legs extending from the periphery of the controlled aperture for precisely attaching the valve to the housing of the transmission oil reservoir.
