After evaluating the $B_c^+ \\to (D_{(s)},D^*_{(s)})$ transition form factors $F_{0,+,T}(q^2)$ and $V(q^2), A_{0,1,2}(q^2), T_{1,2,3}(q^2)$ by employing the perturbative QCD factorization approach, we calculate the branching ratios for all these semileptonic decays. Our predictions for the values of the $B_c^+ \\to D_{(s)}$ and $B_c^+ \\to D^*_{(s)}$ transition form factors are consistent with those obtained by using other methods.
