  Coulomb effects in the neutron-deuteron and proton-deuteron
polarization-transfer coefficients $K_y^{y'}$, $K_z^{x'}$, $K_y^{x'x'-y'y'}$
and $K_y^{z'z'}$ are studied at energies above the deuteron breakup threshold.
Theoretical predictions for these observables are evaluated in the framework of
the Kohn Variational Principle using correlated basis functions to expand the
three-nucleon scattering wave function. The two-nucleon Argonne $v_{18}$ and
the three-nucleon Urbana IX potentials are considered. In the proton-deuteron
case, the Coulomb interaction between the two protons is included explicitly
and the results are compared to the experimental data available at
$E_{lab}=10,19,22.7$ MeV. In the neutron-deuteron case, a comparison to a
recent measurement of $K_y^{y'}$ by Hempen {\sl et al.} at $E_{lab}=19$ MeV
evidences a contribution of the calculated Coulomb effects opposite to those
extracted from the experiment.
