We consider the lepton-flavor violating(LFV) processes $l_{ i}\to l_{ j}\gamma$ in the framework of topcolor assisted technicolor(TC2) models. We find that the new gauge boson $Z^{ \prime}$ predicted by TC2 models can give significantly contributions to these processes via the flavor changing couplings. The present experimental bound on the LFV process $\mu \to e\gamma$ gives severe constraints on the TC2 models. In the case that the $Z^{ \prime}$ mass $M_{ Z}$ is consistent with other experimental constraints, we obtain constraints on the lepton mixing factors $K_{ \tau\mu}$ and $K_{ \tau e}$. The future LFV experiments will be probe of the TC2 models.
