A generalized three-modes optomechanical system is presented where two cavity modes driven by two-tone fields are coupled to a mechanical resonator. We find that two input probe lasers can be entirely absorbed by the mechanical resonator without inducing any energy output from any of the cavity modes termed as coherent perfect absorption. Furthermore, the input probe laser will transmit from one cavity to the other cavity without undergoing any energy loss which is termed as coherent perfect transmission under different parameter regimes. The origin and conditions that enable the phenomena to achieve are analysed, and potential applications in quantum information may be realized in all-optical domain based on these phenomena.
