  In the context of topcolor-assisted techicolor(TC2) models, we study the
contributions of the neutral top-pion $\pi^{0}_{t}$ to the lepton flavor
violating(LFV) processes $l_{i}\to l_{j}\gamma$ and $l_{i}\to l_{j}l_{k}l_{l}$.
We find that the present experimental bound on $\mu\to e\gamma$ gives severe
constraints on the free parameters of $TC2$ models. Taking into account these
constraints, we consider the processes $l_{i}\to l_{j}l_{k}l_{l}$ generated by
top-pion exchange at the tree-level and the one loop level, and obtain
$Br(\mu\to 3e)\simeq 2.87\times 10^{-14}$, $1.1\times 10^{-15}\leq Br(\tau\to
3e)\simeq Br(\tau\to 2e\mu)\leq 4.4 \times 10^{-15} $, $3.1\times 10^{-15} \leq
Br(\tau\to 2\mu e)\simeq Br(\tau\to 3\mu)\leq 1.5 \times 10^{-14}$ in most of
the parameter space.
