We evaluate the time-reversal invariance violation using previous neutron transmission data with polarized neutrons propagating through a transversely polarized $^{139}$ La. By incorporating precise spin observables and the scattering amplitudes into our analysis, we preliminarily constrained the time-reversal invariance violating cross section.
