We study the superconducting transition temperature (Tc) and the Peierls instability temperature (Tp) using Eliashberg type equations for both Tc and Tp self consistently with finite interchain coupling. We show that Tc > Tp below a critical electron-phonon coupling constant which depends on the bare phonon frequency. This determines an upper bound on Tc so that for higher transition temperatures Tp > Tc and superconductivity is unlikely. Higher values of Tc are possible if the interchain coupling is increased above a critical value where the Peierls instability is suppressed.
