Abstract: A transmission oil pan assembly includes an oil pan matable with a transmission case to at least partially define a transmission interior space, and an accessing component for accessing an interior component located inside of the transmission interior space from outside of the transmission interior space. The oil pan is formed with structure adapted to support the accessing component. The oil pan may be formed with an opening adapted to receive the accessing component. A method of selecting an oil pan from an inventory of oil pans with differently disposed accessing components is also provided.

Abstract: A pressure regulating system for a power transmission includes a pressure regulating valve to issue a pressure signal to a load and also a pressure signal to a pressure transducer for feedback to a transmission control module (TCM) which in turn suggests the output pressure of the regulator valve to a desired level in accordance with a pressure command originally issued by the transmission control module. This system provides a closed-loop control for pressure regulation.

Abstract: The present invention provides a pressure control system having a control solenoid with plurality of coils disposed therein, and operable to provide a plurality of pressure gain characteristics to a torque-transmitting mechanism. By selectively energizing the individual coils or a combination thereof, multiple pressure gains may be achieved with a minimum of additional system hardware.
