Summary: Adding the cosmological term, which is assumed to be variable in Brans-Dicke theory we have discussed about a cylindrically symmetric model filled with viscous fluid with free gravitational field of Petrov type-D. The effect of viscosity on various kinematical parameters has been discussed. Finally, this model has been transformed to the original form [\textit{C. Brans} and \textit{R. H. Dicke}, Phys. Rev. (2) 124, 925--935 (1961; Zbl 0103.21402)] of Brans-Dicke theory (including a variable cosmological term).
