Abstract: The method for studying semileptonic neutral kaon decays at CPLEAR is presented together with a preliminary data analysis. For the first time a direct determination of T violation is shown to be possible and low statistics results are given. From the same data the KL-KS mass difference, Δm, the CP violation parameter of KS, epsilon(s), and the parameter x testing the ΔS = ΔQ rule are also obtained.
