By monitoring the quality factor of a quartz tuning fork oscillator we haveobserved a fluctuation-driven reduction in the viscosity of bulk $^3$He in thenormal state near the superfluid transition temperature, $T_c$. Thesefluctuations, which are only found within $100 \mu$K of $T_c$, play a vitalrole in the theoretical modeling of ordering; they encode details about theFermi liquid parameters, pairing symmetry, and scattering phase shifts. Theywill be of crucial importance for transport probes of the topologicallynontrivial features of superfluid $^3$He under strong confinement. Here wecharacterize the temperature and pressure dependence of the fluctuationsignature, finding data collapse consistent with the predicted theoreticalbehavior.
