  Lepton Flavor Universality Violation (LFUV) in $B$ decays in both neutral
$b\rightarrow s l^+ l^-$ and charged $b\rightarrow cl\bar{\nu}_{l}$ processes
observed in the ratios $R_{K^{(*)}}$ and $R_{D^{(*)}}$ is investigated in the
framework of a model based on the extended symmetry gauge $SU(3)_{C}\otimes
SU(3)_{L}\otimes U(1)_{X}$ whose leptonic sector consists of five triplets. It
is shown that in order to explain the experimentally observed deviations from
the Standard Model in these flavor changing transitions, a non-minimal version
of the model has to be considered. We investigate the ability of this model in
accommodating the model-independent scenarios currently favored by global fits.
