Collision experiments with heavy ions at RHIC and CERN help to explore the nature of the deconfined quark-gluon phase. The matter created in such collisions behaves as an almost-perfect fluid indicated by very small dissipative effects. We use the two-flavor NJL model to approximate the QCD physics at high temperatures $T\gtrsim 200\,\text{MeV}$. A large-$N_c$ expansion is applied to include mesonic fluctuations in the fundamental quark sector. We discuss the impact of this expansion to the gap equation and the dynamics leading to a finite shear viscosity of the quarks.
