A motor vehicle includes a transmission and a transmission fluid pump for transport of transmission oil to and within the transmission. The transmission fluid pump has a moving element which is coupled to a summation shaft of a planetary gear train. The planetary gear train has a ring gear which is operated by a first drive, and a sun gear which is operated by a second drive. A freewheel mechanism is arranged between the sun gear or a shaft connected to the sun gear and a further element so that the second drive can be switched off, when the first drive operates at high speeds while yet maintaining proper operation of the transmission fluid pump.

A plastic injection overmolded conductor path structure is disclosed, wherein the conductor paths are entirely surrounded, apart from their connections, by a housing made of plastic, said housing comprising first housing sections produced in a first injection molding process (pre-injection overmolding), and second housing sections which directly adjoin the first housing sections via a contact surface, and which are produced in a second injection molding process (main injection overmolding). The housing is provided with at least one recess of a defined shape and size, in the region of the contact surface.
