  We calculated the weak localization correction to the density of the
transmission eigenvalues in the case of chaotic quantum dots in the framework
of Random Matrix Theory including the parametric dependence on the magnetic
field and spin-orbit coupling. The result is interpreted in terms of spin
singlet and triplet Cooperon modes of conventional diagrammatic perturbation
theory. As simple applications, we obtained the weak localization correction to
the conductance, the shot noise power and the third cumulant of the
distribution of the transmitted charge.
