Abstract
A control unit for an automatic transmission in a motor vehicle includes a housing having an open bottom part with an interior. A carrier is disposed in the housing. Circuit components are disposed on the carrier. Valve coils for electromagnetic hydraulic valves are disposed in the housing and embedded in a flexible compound. A rotational-speed sensor disposed in the interior of the open bottom part is embedded in the flexible compound and thus fixed in its position in the housing. The rotational-speed sensor extends into the vicinity of a gearwheel or of some other rotating component of the transmission and detects or records its rotary motion by induction or the Hall effect.
