  Measurements of the longitudinal spin transfer, $D_{LL}$, and the transverse
spin transfer, $D_{TT}$, of the $\Lambda(\bar{\Lambda}$) hyperon in polarized
$p$+$p$ collisions are expected to be sensitive to the helicity distribution
and transversity distribution of the $s(\bar{s})$ quark in proton and the
corresponding polarized fragmentation functions. This contribution presents the
new preliminary results of the $\Lambda(\bar{\Lambda}$) $D_{LL}$ and $D_{TT}$
using data collected at RHIC-STAR experiment in 2015, with twice larger
statistics than previously published results.
