Beschreibung
Zusammenfassung:	An assembly includes a valve integration unit attached to a transmission oil heater. The valve integration unit includes a valve mechanism and a housing having first to sixth fluid ports for oil input and output. The interior space of the housing has three portions, including a second portion defining a valve chamber and a third portion defining a bypass flow passage between the first and second portions. The valve mechanism has a temperature responsive actuator and first, second and third valve members. The movement of the first and second valve members is actuated by the temperature responsive actuator. The third valve member and the third valve opening are located in the second portion of the interior space. The third valve member is actuatable in response to a pressure differential between the first and second portions of the interior space.
