A composite cover for a portion of a motor vehicle transmission has an integral, internal heat sink to which an electronic controller is attached. The cover, which may be fabricated of any temperature appropriate plastic or composite, closes off and protects that portion of a motor vehicle transmission having electrical and electronic components such as valves, solenoids, motors and sensors. Spaced from the inside surface of the cover where it is subjected on both sides to flow of transmission fluid is a plate or heat sink. An electronic controller is disposed on the outside of the cover and attached by heat transferring mechanical fasteners such as studs or bolts to the plate inside the cover. Preferably, the housing of the controller also includes a heat sink. |
