%X I give a brief review of the weak coupling theory of frictional drag of the coupled quantum well. I then present a theory of frictional drag based on the Kubo formalism that goes beyond weak coupling. Using the T-matrix approximation, I consider the Maki&#8211;Thompson contribution to the transconductivity and obtain a formal result for strong-coupling frictional drag in clean Fermi liquid systems. I discuss how the strong interlayer coupling could affect the temperature dependence of the drag transresistivity.
