Claim of US Patent No. 9,345,139

1. A control module of a transmission control, comprising:
a multi-layer printed circuit board having a first side and a second side;
a first housing part covering the first side and a second housing part covering the second side;
electrical components forming an electrical circuit and situated on the multi-layer printed circuit board; and
one of a casting compound, a molding compound, a foam, and a gel for covering the electrical components of the electrical
circuit, wherein:

the multi-layer printed circuit board connects the electrical components situated in an inner space of at least one of the
first and second housing parts and contact points for contacting at least one further electrical component, the contact points
being situated on the multi-layer printed circuit board outside an area covered by the first and second housing parts,

the multi-layer printed circuit board thermally contacts a cooling element, and
the cooling element is a hydraulic plate of a transmission for a transmission control installed in an automatic transmission.
