In this article we calculate the leading order shear viscosity in QCD using the resummed three-particle irreducible effective action. We work to 3-loop order in the effective action. We show that the integral equations that resum the pinch and collinear contributions are produced naturally by the formalism. All leading order terms are included, without the need for any kind of power counting arguments.
