An electronic automatic transmission controller is provided which is adapted to enable electrical control over automatic transmission devices of the type typically used in motor vehicles. The controller employs a manifold having a number of solenoid valve assemblies mounted thereto. The solenoid valve assemblies feature a low stacked height achieved through the configuration of the valves and various improvements in force output for the solenoid valve assemblies. The solenoid valve assemblies are held in an assembled condition through the action of a bracket assembly which has resiliently deflectable arms which bias against the valve assemblies. Preferably, non-removable fasteners are employed to affix the bracket to the manifold to prevent unauthorized attempts at servicing. The solenoid valve assemblies have protruding terminals which enable a circuit board to be laid against the solenoid valve assemblies such that the board is soldered along a surface opposite the valve assemblies. The automatic transmission controller further features a design which permits automated assembly, thus reducing costs of fabrication. In addition, various improvements in solenoid design are described including a dual working gap system and a design which enables control over spring biasing of a solenoid armature and air gap distance.
