Abstract: The present invention is related to an automatic transmission for a vehicle with an electrohydraulic control. More particularly, the hydraulic control unit and the electronic control unit are mounted adjacent relative to each other on a flange at an end of the transmission.

Abstract: A change-speed transmission in the power train of a motor vehicle has a planetary gearing and coaxial radially inner and outer disc clutches, namely a direct clutch and a reverse clutch. At least that clutch which is engaged (i.e., in use) is cooled by a lubricant for the planetary gearing, and the flow of coolant to the clutches is regulated by the axially movable pressure plate of one of the clutches. A jet pump conveys lubricant from the sump in the transmission case into an axially extending channel of the input shaft of the transmission, and such channel forms part of a system of passages which supply coolant at least to that clutch which is then in use to transmit torque from the input shaft to an output element of the transmission.
