I will discuss uses of the Transiting Exoplanet Survey Satellite for transient and extragalactic science. With continuous monitoring of ~2300 square degrees of the sky for a full month (and ~300 square degrees for 1 full year), as well as <1\% photometry at 16th mag, TESS provides a unique opportunity for transient science. We have built a pipeline to interface with the Transient Name Server API that will automatically extract early-time light curves for precovery of astrophysical transients (and in some cases, late-time light curves for follow-up). This has applications for identifying the progenitors of supernovae, and I will discuss potential for this measurement in 5 bright (<18th mag) supernovae light curves from the first two sectors of TESS observations. We will also search bright galaxies for unknown transients (such as tidal disruption events) and low level variability (that might indicate the presence of Active Galactic Nuclei). Finally, I will describe our search for new kinds of variable objects based on pixel level data.
