**Abstract: **We compute the Euclidean correlators of the stress tensor in pure $SU\left(3\right)$ Yang-Mills theory at finite temperature at zero and finite spatial momenta with lattice simulations. We perform continuum extrapolations using ${N}_{\tau}=10$, 12, 16, 20 lattices with renormalized anisotropy 2. We use these correlators to estimate the shear viscosity of the gluon plasma in the deconfined phase. For $T=1.5{T}_{c}$, we estimate $\eta /s=0.17\left(2\right)$ using an ansatz motivated by hydrodynamics.
