  We identify targets in the Kepler field that may be characterized by transit
timing variations (TTVs) and are detectable by the Transiting Exoplanet Survey
Satellite (TESS). Despite the reduced signal-to-noise ratio of TESS transits
compared to Kepler, we recover 48 transits from 13 systems in Sectors 14, 15,
26, 40 and 41. We find strong evidence of a nontransiting perturber orbiting
Kepler-396 (KOI-2672) and explore two possible cases of a third planet in that
system that could explain the measured transit times. We update the ephemerides
and mass constraints where possible at KOI-70 (Kepler-20), KOI-82 (Kepler-102),
KOI-94 (Kepler-89), KOI-137 (Kepler-18), KOI-244 (Kepler-25), KOI-245
(Kepler-37), KOI-282 (Kepler-130), KOI-377 (Kepler-9), KOI-620 (Kepler-51),
KOI-806 (Kepler-30), KOI-1353 (Kepler-289) and KOI-1783 (Kepler-1662).
