Abstract
A device for regulating transmission oil temperature having a heat exchanger through which the oil flows and to which coolant from an internal combustion engine can be supplied through at least one valve controlled by a thermostatic operating element immersed in the oil, the device includes a flow control body attached to a heat exchanger in a flange-like manner, the flow control body containing an oil channel connected to an oil outlet of the heat exchanger into which a housing enclosing the thermostatic operating element projects for the detection of and response to the temperature of the oil exiting the heat exchanger, the thermostatic operating element having a work piston connected to an extension member which is connected to the at least one valve in the flow control body, the valve disposed between at least one coolant inlet and a coolant opening to the heat exchanger.
